In order to study adaptation ability of 15 commercial olive cultivars, this experiment was carried out using a randomized complete block design with three replication during the period from 2007 to 2009 in dry-warm climate of Sar-pol-e-Zehab Dallaho olive station of Kermanshah province. In this experiment, vegetative and reproductive traits were measured according to I.O.O.C. descriptors. Flora emergence was significantly different over years and among cultivars and flowering period appeared from end March to early May. Korneiki, as the late ripening cultivar, produced the smallest fruits (0.59 gr/fruit) among other cultivars. The highest fruit set, dry matter and content of oil accumulation (12.1%, 12.2%) in fresh matter were recorded in Amphisis and Korneiki cultivars, respectively. Mary was early ripening cultivar and it had the least dry matter and oil in fresh matter (5.2%). Conservalla cultivar had the most fruit weight (4.2 gr/fruit), flesh and yield per hectare (6700 kg/ha). On the other hand, the least percentage of fruit set and yield was obtained in Gorgan1 genotype (720 kg/ha) and Roghani Roodbar cultivar (637 kg/ha). The results indicated that temperature played a major role in delay of flowering by affecting phonological statue and development of flowers. It also oil content in olive affected by environmental condition and genetic background of cultivars. Finally, Olive Table cultivars (Conservalia, Manznilla and Sivillano), Zard-e- ziton (Dual-Purpose) and Oil Amphisis cultivar were better than the others for Sar-e-Pol-e- Zehab weather conditions.

Present study was conducted to consider the effects of different concentrations of 2,4-D and BA on somatic embryogenesis induction, development and maturation of three strawberry cultivars (Kurdistan, Parose and Camarosa). For this purpose, leaf blade, nodal, petiole, stamen and flower bud calli were cultured on Murashige and Skoog (MS) medium supplemented with 2, 4 dichlorophenoxyacetic acid (2,4-D at 0.25, 0.5, 1 and 2 mg/l ) as well as the combination with different concentrations (0.0, 0.25, 0.5, and 1 mg/l) of benzyl adenine (BA). The concentration and kind of growth regulators, cultivar and explant had great importants on strawberry somatic embryogenesis induction, development and maturation. Results obtained from the studies revealed that all explants with the exception of petiole and stamen incubated on medium formed embryonic calli. MS medium supplemented with combination of auxin and cytokinins were evidently higher than those in the single auxin treatments. 1 mg/l 2,4-D + 0.25 mg/l BA yielded the highest percentage of embryonic calli and number of globular embryo stage and 0.5 mg/l 2,4-D + 0.25 mg/l BA yielded the highest number of embryo cotyledonary in all types explants. The leaf explant calli and Parose cultivar were the most responsive to produce to somatic embryogenesis induction, development and maturation.
