摘要：应用生长调节剂对板栗处理的结果表明,BA 1 000 ppm促进了结蓬量、出实率及单株产量而抑制了新梢的粗生长和叶片扩大;青霉素150 ppm和自配的稀土制剂RS 300 ppm都能增加出实率,前者能明显促进雌性成花并对抑制新梢伸长生长有一定作用,后者则加速了新梢的粗生长;自配的生长调节剂MN 500 ppm在雌性成花、结蓬量、出实率和单株产量四个方面具有显著的促进作用,而且无其它方面的不良影响;PP_(333) 500 ppm在一定程度上能提高结实率并减缓新梢伸长生长,同时也抑制了叶片扩大;GA_3200 ppm尽管能增加结实率,但主要表现为加速新梢伸长生长,减少结蓬量,抑制雌性成花,降低雌雄比例,显示出雄性化趋势。对内源激素的分析结果也表明,较高浓度的GA_3更利于雄花分化及发育。
It has been evident from the treatment of PGR to Chinese Chestnut that BA(1000 ppm) promotes fruit bearing number,seed rate and individual tree yield while inhibiting the growth of new shoots the expansion of leaves area; both penicillin and RS(300 ppm,a mixture of chemicals with rare-earth elements) can increase seed rate, but, the former also promotes the formation of female flower and prevents from the stretch of new shoots, the later, on the other hand, has a lot to do in promoting the diameter growth of new shoots; MN(500 ppm, a special combinations of PGRs) has significant effects on promoting the formation of female flower, fruit bearing number, seed rate and individual tree yield; PP333 (500 ppm) can increase seed rate in some extent but retarding the expansion of leaves area; GA3 (200 ppm) though can increase seed rate, it promotes the growth of new shoots greatly as well, thus inhibiting the formation of female flower and reducing female/male flower ratio and fruit bearing number. The results of analysis on internal hormones suggest that higher GA, concentration is more favorable to the development of male flower.
