canola genotypes reaction to stopping irrigation was surveyed. this experiment was carried out as a split plot randomized block design whit three replications in the safiabad argicultural research center for two years. main plot was considered of different levels of stopping irrigation (stopping irrigation at the ending flowering, poding, 10% and 30% ripening of pods in main stem ) and sub pl...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
A research was conducted in Southern Italy to study the changes in seed yield, oil content andfatty acids composition, in response to irrigation at different stages of growing season (at sowing,Dry; from sowing to beginning of flowering, S-BF; from visible bud to 75% flowering, VB-FF;from beginning of flowering to seed ripening, BF-M; from sowing to seed ripening, Full), in astandard sunflower ...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Climate is one of the main factors that affect plant behavior. The phenology of Guarea macrophylla Vahl, which is a small tree used for reforestation of degraded areas, was monitored for 18 months in a riparian forest at the Schmidt Stream, Campo Bom, in the state of Rio Grande do Sul, southern Brazil. Vegetative (leaf fall and leaf flushing) and reproductive events were observed, with the latt...
Regarding the sensitivity of citrus fruit to low temperatures and the conjunction of the fruit harvest season with cold days of the year necessisates more research on physiological effects of cold-stress damages. In this study, five citrus cultivars including Sanguinelli blood orange, Local lemon, Valencia orange, Unshiu mandarin and Local orange were stored under various cold treatments (3, 0,...
Peach (Prunus persica L. Batsch.) is produced in most areas of Iran, where flowering is hindered by temperature. Using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. The objective of this study was to determine the effects of methyl jasmonate (MJ) and salicylic acid (SA) on peach bloom delay and yield. This study evaluated the applications of MJ 0 (contro...
Among the single treatments tested under in vivo addition of well decomposed FYM 20 tons per hectare as soil amendment recorded minimum wilt incidence of 3.75, 24.76 and 48.25 % at flowering, fruit formation and ripening stages of chilli crop, respectively, with 61.31 q ha fruit yield as compared to check (42.50 q ha). Dual application of Trichoderma viride 0.16 t ha + FYM 20 t ha recorded mini...
