To study the effects of chilling on dormancy breaking and the increased germination characteristics of Nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. Factor A was the chilling treatment in three levels (control, one-month and two-month ...
In many forage legumes, hard seed coat is the main problem impeding thegermination by preventing water and gases transport in seed. We evaluated theeffects of mechanical scarification, chilling, different seedbeds (peat and sand) andtheir combination on the germination ratio and time of 9 naturally grown legumespecies belonging Lathyrus and Vicia genus. Control seeds showed very lowgermination ...
The effect of chilling on photosystem II (PSII) efficiency was studied in the variegated leaves of Calathea makoyana, in order to gain insight into the causes of chilling-induced photoinhibition. Additionally, a relationship was revealed between (chilling) stress and variation in photosynthesis. Chilling treatments (5 degrees C and 10 degrees C) were performed for different durations (1-7 d) un...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Watermelon fruit from Crimson Tide (CT) and Crisby (CR) grafted onto Ferro, RS841, Argentario, Macis rootstocks ungrafted CT CR were compared for effects of low temperature storage on chilling injury, physical biochemical changes at 0°C 85‒90% relative humidity 21 days. After storage, hold to 21°C 75‒80% 7 days determine shelf life. Quality analyses determined during life a weekly interval. The...
The seeds of two species (Citrulus colocynthis) and (Silybum mrianum) gathered from natural habitat located in the Koohdasht city (Lorestan province) and transferred to Kermanshah Agricultural and Natural Resources Research and Education Center in the summer of 2014. For each species, separate experiments in a completely randomized design with 14 treatments and 4 replications were done. Treat...
Among the chemicals that their effects on reducing chilling injury has recently been studied are salicylates and jasmonates. Therefore, in this study the effects of salicylic acid and methyl jasmonate on increasing the cold tolerance of bell pepper cv. Emily was examined. Experiment was done as a 7×2 factorial in the completely randomized design (CRD) with four replications. The first factor co...

Adaptive neuro-fuzzy inference system (ANFIS) and genetic algorithm–artificial neural network (GA-ANN) were investigated for predicting methyl salicylate (MeSA) effects on chilling injuries and quality changes of pomegranate fruits during storage. Fruits were treated with MeSA at three concentrations(0, 0.01 and 0.1 mM) and stored under chilling temperature for 84 days. ANFIS and GA-ANN models ...
The cabbage butterfly, Pieris melete hibernates and aestivates as a diapausing pupa. We present evidence that the optimum of low temperature and optimal chilling periods for both summer and winter diapause development are based on a similar mechanism. Summer or winter diapausing pupae were exposed to different low temperatures of 1, 5, 10 or 15°C for different chilling periods (ranging from 30 ...
