Seed production depends on many factors. In this study, two independent experiments were carried out to investigate the effects of pollination time, crossed node spacing, male flower age, number of crossings on each plant and deletion/non-deletion of other fruits in the crossed nodes on the cross-ability and seed production in greenhouse cucumber. In every experiment, three mentioned factors were assayed based on factorial experiment as a randomized complete block design. Crosses were done on 10 plants in every replication of treatments. The results showed that pollination at 8:00‒9:45 AM, led to higher amount of full seed weight in contrast to other times of pollination. Increasing crossed node spacing from 2‒3 to 4‒5 nodes led to an increase in the number of empty seeds, which was ascribed to the reduced seed production. The highest amount of number of seeds per fruit, seed weigh and number of full seeds were obtained when young male flowers were used. Moreover, higher seed production was obtained from five, instead three crossings on each plant, and the non-deletion of fruits on the crossed nodes. Overall, higher percentage of seed production per fruit was obtained when crossing was done with young male flower in early morning and high number of crossing in every plant.

Thirty-four sugar beet drought-tolerant half-sib families were screened in greenhouse experiment under saline (16 dSm−1) and normal conditions, and a subset of 10 tolerant genotypes were selected f...

Two studies were conducted to find the effects of zeolite in soilless cucumber culture. Zeolite was enriched by essential cations (Zcat) for some treatments and with essential cations plus iron sulfate (Zfe) in others. In 2010, various ZFe levels were compared with various amounts of iron in irrigation water and various zeolite levels in two enrichment methods were studied. In 2011, various ZFe levels mixed with Peatlite and also perlite were compared with various amounts of iron in irrigation water. The effects of treatments on iron concentration of leaves were not significant, which could be because iron was supplied by releasing it from zeolite. Using ZFe as iron resource increased the yield and vigor of plants in proportion to iron chelates. Enrichment methods did not have significant effect on measured traits. ZFe had provided iron requirement of plant. Perlite in comparison to Peatlite did not affect iron absorption.

The effect of line, tempering solution, temperature, and soaking time were investigated on water absorption, splitting, and texture of two Iranian red kidney beans including Akhtar and Derakhshan to determine the best line and the best soaking conditions for industrial use. Akhtar line showed higher level of water absorption in comparison to Derakhshan line. Water absorption of unblanched red beans at 2.5 hour soaking was two times greater than water absorption of blanched ones for both lines (p
