| 摘 要： | 甜椒在逆境条件下易发生落花，研究结果表明：PCPA与NAA对花粉发育有不良影响，减少落花生理效应不是促进受精，而是调节了生长发育，应用PCPA、NAA后能在逆境条件下保蕾保花，提高座果率；而且气象因子对药剂干扰很明显、因此，只有与改善栽培条件结合，才能较好的发挥PCPA，NAA的实际应用效果。

| Abstract: | The flowers of' sweet pepper (Capsicum annuum Vau grassum send)easily fell down understress conditions. The results of' this experiment showed that PCPA or NAA had adverse effectS on thedevelopment of pollen, The physiological effects of lowering flower were improvin growth anddevelopment rather than improving the fertilization of pollen. The treatments of PCPA and NAA couldincrease rate of fruit setting by keeping buds and flowers under stress colnditions'The meterologicalfactors evidently influenced the effect of treatments. Thus the combining treatments of' PCPA or NAAwith the improving cultural covditions could improve the effectiveness of these agents. |
