In order to determinate the self–incompatibility and the most suitable pollinizer for Esfahan commercial quince cultivar, the effects of four different pollinizer treatments ((KM1, PK2, Kvd2, NB4), as self pollination and open pollination) on fruit set and quantitative and qualitative characteristics of commercial quince fruits of Isfahan were studied in a randomized complete block design with 4 replications in quince orchards of Felavarjan region during 3 years. The results of fruit set percentage showed that the mean comparison test had a significant difference between different pollination treatments, except (KVD2, NB4). The maximum fruit set percentage was 23.42 which were related to KM1 genotype, and the minimum percentage was 8.4 which were related to the self pollinated treatment. The mean comparison of self pollinated treatments on fruit weight had a significant difference between KM1 and other treatments. The investigation of quality and quantity characteristics of fruit results showed that there was a significant difference between the Total Soluble Solids (TSS) and firmness. The KM1 genotype (Isfahan sour quince) with 80% of overlap flowering period with 23.42 % of fruit set during three years is chosen and introduced as the best pollinizer for the Isfahan quince cultivar.

A study of two years was carried out on apples, red delicious cv. in Comeh of Semirom region. The objective of this research was to assess the effect of pre-harvest calcium phosphate (Seniphos) spraying and summer pruning on the skin color and quality characteristics of the fruit. Study was carried out using a complete randomized block design with 3 replications. Trees were subjected to pre-harvest spraying of 0.8, 1% and 1.2% seniphos (calcium phosphate) and pruning on 6 and 21 of august. A control test also was carried out. Each block contained 3 trees. 15 kilo of fruit was harvested randomly from each block. Firmness, skin color, acidity, TSS, overall acceptability, bitter rot, rotting and farinaceous texture of fruit were assessed after 2 and 4 month storage at 4 ºc and 95% of humidity. ANOVA test based on 2 year study data indicated significant effect of applied treatments (α=1%) on all studied parameters. Skin redness increased significantly comparing to the control sample. The highest redness was observed in the 1.2% seniphos spraying treatment. After 2 months of storage, firmness farinaceous texture, bitter rot and overall acceptability of fruit in seniphos and summer pruning treatments changed significantly comparing to those of control sample. After 4 months of storage, there was significant difference between 1.2% seniphos treatment and other treatments including the control in view point of firmness, rotting, farinaceous texture and bitter rot of the fruit. The acceptable firmness and overall acceptability were obtained by using 1% and 1.2% seniphos spraying treatments.
