Self-incompatibility, low yield and fruit set represent important factors influencing the pear production in Iran. Some compounds such as polyamines and the mixture of some mineral elements like SICS could be suitable to decrease above concerns. The trail included putrescine (Put) (0.1, 0.25 mM), both spermine (Spm) and spermidine (Spd) (0.05, 0.25 mM) and SICS (1, 2 mg/L) in (self and open) pollination and control. Spd (0.25 mM) in open pollination mode showed the highest yield per branch and fruit set in comparison with control. Spermidine (0.25 mM) in self-pollination mode was the best treatment for fruit length and diameter. In self-pollination mode, Spd (0.05 mM), Spm (0.25 mM) and SICS at 2 mg.L showed the significantly increase in irregular fruit shape. Spd and Put (0.25 mM) in self-pollination showed the best fruit volume among all of the treatments at both of pollination mode

自交不亲和控制物质对梨梨(Pyrus communis L. Cultivar'Williams)产量和水果生长特性的影响

自交不亲和,低产和坐果是影响伊朗梨产量的重要因素。一些化合物(如多胺)和某些矿物质元素(如SICS)的混合物可能适合降低上述担忧。试验结果包括在(自体和开放式)授粉和对照中腐胺(Put)(0.1,0.25 mM),精胺(Spm)和亚精胺(Spd)(0.05,0.25 mM)和SICS(1、2 mg / L)。与对照相比,开放授粉模式下的Spd(0.25 mM)显示每枝和坐果的最高产量。自花授粉模式下的亚精胺(0.25 mM)是处理果实长度和直径的最佳方法。在自花授粉模式下,2 mg.L的Spd(0.05 mM),Spm(0.25 mM)和SICS显示出不规则果实形状的显着增加。Spd和Put(0。
