研究不同浓度青霉素对板粟花性别分化及其部分形态特征和生理特性的调节效应，结果表明，100mgL’青霉索处理可显著促迸板栗雌花分化和新梢加粗生长，抑制雄花分化和新梢伸长生长，调整雄花雌花数比，提高树体氮代谢水平和光合作用强度。而300和500mgL’青霉素处理虽也具促雌抑雄效应，但同时也刺激新梢伸长生长，对提高树体氮代谢 水平、光合作用强度和新梢加粗生长效应不明显。6—BA和CCC对青霉索有一定的协同或抑制作用。
The effects of different concentrations of penicillin on sexual differentiation and some morphological and physiological characteristics of Populus davidiana were studied. The results showed that 100mgL ’Penicillium sibiricum could significantly promote female flower differentiation and boll growth of chestnut and inhibited male flower differentiation and shoots Elongate growth, adjust male flower number ratio, increase nitrogen metabolism level and photosynthesis intensity. While 300 and 500mgL penicillin treatment also had the effect of male and female, but it also stimulated the elongation of shoots, which had no obvious effect on increasing nitrogen metabolism level, photosynthesis intensity and bolting growth of shoots. 6-BA and CCC Penicillium has some synergy or inhibition.
