Pseudohandelia Tzvel. belongs to the Asteraceae family with only one species. It is endemic to Khorasan Province in Iran. Having partially big and beautiful inflorescences make it a proper choice in urban green space especially in case of mass culture. In this research, to investigate possibility of micro propagation of this plant two separate experiments were designed. To obtain non contaminated explants, seeds were cultured in MS media in February 2009. After about two months a few healthy plants as stock plants for use in later stages produced through subculture. In the first stage, to evaluate amount of callus production, a factorial experiment based on a randomized complete design with two factors conducted. The first factor was 12 different hormone levels (including BAP, IAA, KN and 2,4-D with different concentrations) and second factor was explants type (including leaf, apical and lateral buds as a explants) making 36 treatments in total. In the second stage to induce stem on produced callus a randomized complete design with 34 treatments (including mentioned hormonal treatments, base MS media and different explants) was used. At the end the callus with stems were transplanted to a MS media containing IBA for root production. The results of the first experiment showed callusogenensis response to above hormonal treatments was seen in this plant with the exception of 2,4-D. Significant difference among the means of hormonal treatments for fresh weight of induced callus was observed. The result of the second experiment showed limited treatment could produce stem and most of treatments just produce callus. Also those samples that produced stem, a few could produce root in MS media.

Seedlessness is the most important trait in table grape and raisin industry which has attracted breeders from long ago. Breeding grapes by traditional methods result in low number of seedless progenies and their selection requires long time. Therefore, marker-assisted selection (MAS) can overcome the selection difficulty and would decrease high cost of progeny maintenance for several years. In this study, SCC8 marker was employed to evaluate its efficiency in early discrimination of seedless progenies as well as the status of sdI gene in seedless and seeded important Iranian grape cultivars. To do so, 11 progenies which were realized as seedless by panel test, were evaluated Scar marker Scc8. According to the results, Scar marker Scc8 could identify 10 of them as homozygous seedless and just one as homozygous seedless. This marker could also identified 'Muscat of Hamburg', 'Dastechin', 'Shahani', 'Sahebi', 'Khalili', 'Alibaba', 'Qhezel Ozum', 'Dizmari' and 'Shirazi Qermez' as homozygous seeded cultivars whereas 'Atabake', 'Shahroudi' and 'Toloqhi' were found to be heterozygous seeded ones. It can be concluded that Scar marker SCC8 could discriminate seedless progenies as well as cultivars and their sdI gene status correctly in most cases (87.5%).

Cross pollination in some of apples cultivar exists; also Iran is near the origin of apple trees so, large genetic diversity can be seen between Iranian cultivar. Also very famous apple cultivar is known in Iran for special flavor and taste. The name of this cultivar is Golab. This research was studied in the years 2010 and 2011 in Khorasan Razavi Province on Golab apple ecotypes to evaluate characteristics of Golab apples in Khorasan region, providing keywords for Identification, collect valuable ecotypes, preventing extinction and also use in apple breeding. Ecotypes were including: Golab Torbat Heidariyeh, Golab Sabz Pishras, Golab Kermanshah, Golab Kohanz, Golab Bahareh Shoghan. 31 qualitative and quantitative traits about fruit characteristics in a completely randomized design with 10 replicates to valuate these ecotypes were investigated. Average comparison showed that the greatest variability between cultivars was at the traits like: fruit weight, fruit firmness, fruit skin thickness, pH and TSS. The correlation results showed that the most significant positive correlation exists between fruit weight and stylar end width (0.92±0.06), fruit tail and fruit weight (0.87±0.07), Length to width ratio of fruit with fruit weight (0.85±0.08).

Pomegranate is one of the major horticultural crops in Iran, but studies about this product; especially its pruning is very little. Therefore this study was carried out to assess the effect of pruning and nutrition on pomegranate cultivar “Robab” in Qaemieh, Fars province during 2008-2009. This research was conducted factorial experiment based on randomized complete block design (RCBD) with 5 pruning treatments (P1, P2, P3, P4, P5) and 3 levels of NPK (0, 250 and 500 gr per tree). Our results showed that yield, juice volume, fruit and aril weight had negative correlation with pruning severity, but had positive correlation with NPK fertilization rate, as trees with P3 pruning treatment receiving fertilizer had Yield, juice volume, fruit and aril weight more than other treatments. Fruit skin thickness had negative and positive correlation with nutrition and pruning rate, respectively. Nutrition had no significant effect on total soluble solid (TSS), while all pruning treatments increased fruit total soluble solids. Pruning reduced the amount of citric acid. Also, there was direct relationship between titratable acidity (TA) and ascorbic acid with nutrition.

Tuberose flower (Polianthes tuberosa L.) is an important commercial cut flower in the world, however the short vase life is one of its major problems. So, an experiment was carried out by using five different levels of humic acid (HA) mixed with sucrose and seven different levels of silver nanoparticles (SNP) mixed with sucrose in vase solution on tuberose cut flowers cv." Single". The results indicated that there were significant differences between treatments. The decline of fresh weight in flowers treated with 25, 50 and 75 mg L-1 HA was fewer compared to other levels. Also, the effect of HA on vase life and water uptake index was significantly higher in 25 mg L-1 HA (2.25 days more than control). SNP treatments increased the water uptake, fresh weight, total protein and declined lipid peroxidation amount compared to the control flowers. The results also showed that flowers which were treated with 1 mg L-1 SNP had 2.87 days vase life more than the control flowers. To sum up it can be demonstrated that suitable levels of HA and SNP improved better morphological and physiological properties and eventually increases the vase life of cut tuberose flowers.

In recent years the use of organic and biological modifier as an environmental friendly replacement for chemical fertilizers has been used more. In order to study the effect of different levels of biological fertilizers and mushroom compost on flower yield and characteristics of saffron corms (Crocus sativus L.), a split plot experiment based on RCBD design with three replications was conducted in 2009-2011 growing season in research farm of Ferdowsi University of Mashhad, Iran. Plant growth promoting rhizobacteria (use and non-use of Nitroxin) and spent mushroom compost levels (SMC) (0, 20, 40, 60, 80, 100 t ha-1) were considered as the main and sub factors. The results showed that Nitroxin had positive effect on all studied traits, for example the use of Nitroxin increased number of buds per corm by 12 percent compared to the control. Based on the results, levels of 20, 60, 80 and 100 t ha-1 of mashroom compost increased the total weight of corm without scale by 48, 24, 30 and 29 percent respectively compared to the control. Interaction effect of plant growth promoting rhizobacteria and different levels mushroom compost was significant on flower yield, so that in condition of use and non-use of Nitroxin, levels of 60 and 100 t ha-1 mashroom compost were better than other treatments. According to the results, Nitroxin in combine with 40, 60 and 80 t ha-1 mushroom compost increased stigma yield 77, 66 and 30 percent, compared to the same levels in condition of non-use of Nitroxin. In general, the results showed that it seems use of biological fertilizers and appropriate amount of mushroom compost in addition to the maintaining stability of agroecosystems, can improve quantitative and qualitative characteristics of saffron.

This research was carried out in order to evaluate the influence of different concentrations of ethanol and methanol (0, 4, 6 and 12%) and two pulse treatments (12 and 24 hour) on longevity of cut standard-carnation (Sensi cultivar) in a factorial based on randomized completely design with three replications, at Tehran University, Aboreyhan Pardis, horticulture department, during 2010. The results showed that the effect of alcohol treatments and interaction effect of alcohols and pulse on vase life were significant (at what level?????), whereas solution uptake and relative fresh weight were not affected by mentioned treatments. The highest (17.33 day) and lowest (11 day) amount of carnation vase life were obtained by ethanol 12% at pulse of 12 hours and control treatments, respectively. Ethanol 6% at pulse of 24 hours, ethanol 12% and methanol 6% at pulse of 12 hours were more effective in increasing the longevity of carnation than other pulse, while in other treatments, no significant differences were observed between the pulse times. Moreover, the highest of ethylene production obtained by control, while ethanol 4% and 6% at pulse of 24 hours, ethanol and methanol 12% at pulse of 12 hours and methanol 6% at both time of pulse markedly decreased the production of ethylene and lead to significantly increase in vase life. The relative extension of flowers and relative fresh weight had a positive correlation with vase life, while solution uptake had non correlation or negative correlation with other treats.

In order to decreasing drought stress injuries and recognizing red peppers tolerance physiology against drought stress in greenhouse conditions, an experiment with three levels of drought stress (irrigation at 100, 60 and 30% of field capacity) and four concentrations of 5-aminolevolinic acid ((ALA; 0, 0.25, 0.5, and 1 mM)with four replications in an experimental was 3×4 factorial experiments in a randomized completely design was conducted in greenhouse of Agricultural Faculty of Ilam University. In the end of experiments, parameters such as ascorbate peroxidase activity, total antioxidant activity, malondialdehyde content, ascorbic acid, relative water content, plant height and number of lateral buds was evaluated. The results showed that with increasing drought stress severity the growth parameters decreased significantly but ascorbate peroxidase activities, total antioxidant capacity, malondialdehyde and ascorbic acid content increased. Foliar application of AHA reduced malondialdehyde content and improved other evaluated traits. ALA protected cell membranes by reducing malondialdehyde content and lipid peroxidation. In addition, ALA with increasing ascorbate peroxidase activity, total antioxidant capacity and ascorbic acid contents in plants improved physiological traits and drought stress resistance.

The different factors such as harvest time, product handling, temperature and storage duration can be influenced on the different properties of citrus fruits and has considerable economic consequences. Therefore a factorial experiment based on completely randomized design with 3 replications was performed to evaluate the effects of harvest times (start of color change, 50% of color change and full color change of fruits), storage period (0, 25, 50 and 75 days) at 7ºC on total soluble solids, titrable acidity, ascorbic acid, total phenol content, flavonoid, antioxidant capacity, anthocyanin and activity of L-phenylalanin ammonia-lyase. The results showed that the harvest times and storage period had significant effect on the measured properties. So that the after 75 days of storage, peak phenylalanin ammonia-lyase activity and total flavonoid observed concomitantly with the accumulation of anthocyanin in ripe blood orange fruit but decreased antioxidant capacity and total phenol after 25 days of storage. Also, the highest vitamin C content and total soluble solids were measured in full ripening of fruits before storing and decreased after 75 days storage. So, according to changes in all of measured characteristics, the apropriate time of harvesting of Moro blood orange was the stage of commercial maturity of fruits.

To study the effect of foliar application of humic acid on morpho-physiological traits, nutrients uptake and postharvest vase life of cut marigold, an experiment was conducted with five levels of humic acid (0, 250, 500, 750 and 1000 ppm) based on completely randomized design with three replications. Based on the results, in compared with control, leaf number and leaf area, total phenol and aerial and root dry weight significantly influenced by humic acid. Accordingly, the highest flower number in compare with control plants was observed in 250 and 500 ppm concentrations. Also, foliar application of humic acid showed a significant effect on phosphorous and calcium uptake (P

In order to study the different concentrations of gibbererlic Acid and girdling on quantity and quality improvement of grape cv, Askari an experiment was carried out in kashmar region on 2012 as factorial in a complete randomized block design.In this experiment the effect of gibberellin at four concentration in two time of flowering and girdling at four time in four replication were performed. Results showed that, gibberellins and girdling treatments increased the pH level relative to control. Highest pH in gibberellin treatments related to 200 ppm with 3.85 mean and in girdling treatments related to 4 weeks after flowering with 3.575 mean. Also the highes content of titratable acidity in gibberellin and girdling was 200 ppm with mean of (% 0/913) and 4 weeks after flowering with mean of (%0/842) and lowest tss belong to control (%0/6107). The highest tss contents belong to 150 ppm gibberellin treatment and in girdling treatment related to 4 weeks after flowering and lowest contest belong to control (%14/75).based on the results of this study we can ve commended gibberellin and treatment in order to enhance the qualitative and quality features of grape cv. askari
