摘要
通过对扁桃甘肃分布区主栽品种花粉活力的测定和不同品种间的人工授粉试验,结果表明:该区扁桃坐果率低的原因之一是花粉活力低,授粉品种搭配不当;使用不同的化学药剂处理,发现40mg/LNAA能显著地提高扁桃的坐果率。
The pollen vitality of the almond varieties grown i n Gansu province was examined and artificial pollination among them was carried out.Results indicated that low pollen vitality and incompatible pollinators wer e one of the reasons caused the low fruit-set rate of almond.Practice proved t hat spraying40mg/L NAA could significantly promote the fruit-set rate of al mond.
