【摘要】 为了抑制蜜本南瓜侧蔓的生长,提高果实的商品性,研究了喷施不同浓度萘乙酸(NAA)对蜜本南瓜生长发育的影响。结果表明:萘乙酸处理对蜜本南瓜营养生长有抑制作用,随着喷施浓度的增加,侧蔓数逐渐减少、侧蔓长度和主蔓长度逐渐缩短;在200 mg/L浓度范围内,喷施萘乙酸使蜜本南瓜的单株结果数减少,单果重增加,畸形果数减少,商品果产量提高;处理浓度超过200mg/L时,畸形果数量反而增加,单果重和商品果产量均下降。更多还原

【Abstract】 In order to improve the fructivorous commodity of honey pumpkin by inhibiting the growth of lateral branches,different concentrations of naphthalene acetic acid(NAA)were used to foliar spraying.The results showed that NAA inhibited vegetative growth of the honey pumpkin. The numbers,length and main stem length of lateral branches gradually decreased with increasing concentration of NAA;and that the numbers of fruites per plant,fruit weight increased and the numbers of deformed fruit reduced,commodity production increased when the concentration were less than 200mg/L;but when the concentration were higher than 200mg/L,the numbers of the deformed fruit increased and fruit weight and commodity production are reduced.更多还原
