To investigative the effect of benzyladenine and eliminate of irrigation in winter on vegetative growthparameters and chemical composition of tree and nut quantitative characteristics of pistachio trees cv.Kaleh-Ghoochi, an experiment was done in 2010 to 2012 years. In this study, the effect of two irrigationregimes includes irrigation and non-irrigation in winter combined with three levels of benzyladenine (0,20 and 40 mg L-1) was investigated. The experiment design was randomized complete block design withthree replications. The data obtained from both experiment analyzed as the combined analysis. Irrigationtreatment was done as similar as common irrigation program in orchard, and in non- irrigation treatment,there wasn’t irrigation from January to April in both years. Application of benzyladenine treatment wasdone at inflorescence buds swollen time. The results showed, 40 mg L-1 benzyladenine had the mosteffective on vegetative growth of trees compared with the other treatments. Also benzyladeninetreatments compared with the control had significant increase in the ecophysiological parameters; leavesbiochemical compounds contents, leaves nutrient elements concentration and caused reducing inpercentage of early splitting fruit and bud abscission significantly. Also, results showed that eliminationof irrigation in winter had no significant effect on the mentioned parameters. Thus, based on the results ofthis study it seems that elimination of winter irrigation doesn’t have any effect on vegetative growth anddevelopment of pistachio tree, but application of BA in late winter has positive effects.

To investigate the effects of salinity stress on some germination and vegetative growth indices of lentil (Lens culinaris Medic) genotypes, two separate experiments were conducted at glasshouse and laboratory of College of Agriculture, Vali-e-Asr University of Rafsanjan. In the first one, three electrical conductivities (including one, three and seven dS.m-1) were applied on germinating seeds of seven accessions and two cultivars of lentil and germination indices were investigated. In the second experiment, same salinities were applied on soils of pots on the same genotypes. After four weeks, dry mass and leaf areas were measured. Results showed that germination percentage, radical to plumule ratio, leaf area and dry matter per plant reduced with increasing in salinity levels; however there was no significant difference between EC= 4 and 7, except for germination percentage. On the other hand, considerable genotypic variation was observed in response to salinity in both stages but there was no significant correlation between tolerance to salinity in germination and vegetative growth phases. In the situation of this study, it seems that damage to growth at germination and vegetative phase induced by EC= 7 was relatively higher than EC=4.
