This study attempts to evaluate the effects of planting date and spraying CCC on some biochemical characteristics and qualitative and quantitative yield of sugar beet. It has conducted an experiment, using a Split factorial based on randomized complete block design with three replications in 2015-2016 growth season in field experiment of university of Abourayhan, Tehran University. The treatments include planting date (2nd of October and 22nd of October) as the main factor and cultivars (Suprima and 9597) and foliar spraying (1000 ppm) / non-application of CCC as sub plots. The results show that the highest percentage of bolting (54.58%) and sodium content (equivalent to 9.16 mEq / 100 g of sugar beet pulp) take place on October 2, while the highest root yield (26.15 ton per hectare) and white sugar yield (equal to 1.44 tons per hectare) happen on October 22. Also, it has been observed that most values of the studied traits (except bolting percentage and sodium content of sugar beet pulp) have occurred through the cultivation of Suprema with CCC spraying. Overall, it can be concluded that the best conditions to determine the best root and sugar yield in the area of research, on 22nd of October, the Suprima and application of 1000 ppm are recommended in order to cultivate sugar beet in the Pakdasht area.

In order to examine the germination response of basil medicinal plant’s seeds (Ocimum basilicum L.) to temperature and determination of cardinal temperatures for germination percentage and rate, a compound decomposition experiment was performed through a fully random design with four reptile and six thermal levels (8, 15, 20, 25, 30, and 35 degree centigrade) in seed technology laboratory of Abou-Reyhan campus in Univerity of Tehran. In this study, 22 Basil masses were evaluated including “Tehran”, Green Shahr-e-Rey”, “Green Birjand”, “Purple Birjand”, “Green Shiraz”, “Green Zabol”, “Zahedan”, “Green Zahedan”, “Kermanshah”, “Green Pishva”, “Purple Pishva”, “Green Malayer”, “Khash”, “Local green Tonekabon”, “Green Isfahan II”, “Purple Isfahan II”, “Green Isfahan III”, “Green Isfahan IV”, “Green Mash’had”, “American green Napolta”, “Italian Genovese”, and “Switzerland” . Based on the results of variance analysis, temperature impact, genotype, and their interaction on germination percent and germination rate was significant at the 5% level. Optimal range of temperature for germination percent and germination rate was obtained as 19.10-27.78 and 20.32-29.89 degrees centigrade, respectively. In most masses, the highest germination rate was observed at 25 degrees centigrade. Among all evaluated masses in current research, Isfahan III was appropriated the highest germination rate in all temperatures. The results of experiment showed that the response of germination percentage and germination rate to temperature was well described through Beta function and segmented function, respectively, and cardinal temperatures can be determined for Basil using these two models.
