the main objective for plant breeding is to increase genetic diversity. mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. the present research was aimed to compare efficacy of different doses of gamma rays (150, 200, 250, 300 and 350 gy and zero dose control) on the sesame morphological ...

The effects of sodium chloride (NaCl) salinity (control; canal water with 0.4 dS m-1), 2.5 dSm-1, 5.0 dS m-1, 7.5 dS m-1 and 10.0 dS m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (Rosa hybrida L.) cultivars viz. ‘Kardinal’, ‘Angelique’ and ‘Gold Medal’ were studied to achieve better management, quality product...

abstract the quantative and qualitative yield comparison of three cucumber f1 cultivars including' sina, amyral, and negin was evaluated using 3×3×3 factorial experimental design with six replication. three types of pruning treatments were applied; cutting down all branches on main stem (b1), leaving one node and the leaf next to it on all branches (b2), leaving two node and the leaf next to th...

Anecdotal evidence gathered from pruning crew observations indicates that there may be enhanced branch growth at the new crown base in young pruned coastal Douglas-fir (Pseudotsuga menziesii var. menziesii) trees compared to unpruned trees. This has the potential to reduce the quality and value of the stem above the pruned portion of the bole. An analysis of the size of branches in the remainin...

introduction fertilizers are the key components which provide plant nutrients' needs in recent years (omid jangir & sing, 1996; kapoor et al., 2007). in many cases, using chemical fertilizers has different negative environmental effects such as soil, water and air pollution, which increase environmental hazardous and production costs (jangir & sing, 1996; kapoor et al., 2007). biological activi...

one of the most important operations in managed gardens is pruned grapes. for evaluate the effect of pruning short, medium, heavy on yield and yield components of taif grapes, before and after the cold winter, in the years 2012 to 2013, a factorial experiment in a crbd design with five replicates were performed on two factors. the first factor was the number of buds per stem and included the th...
