摘要
【目的】研究不同生长调节剂对西葫芦商品瓜外观性状、产量及品质的影响。【方法】以西葫芦品种迁葫2号为试验材料,采用不同生长调节剂(4、5、6、10 mg/L瓜丰和1 mg/L千手)喷施西葫芦叶片,以清水喷施处理为对照,分析生长调节剂对商品瓜外观性状、产量及品质的影响,并采用灰色关联度法分析各指标与产量的相关性。【结果】1 mg/L千手处理极显著提高西葫芦商品瓜单瓜长、果实横径(P<0.01);单株瓜数低于对照,产量降低。瓜丰处理对西葫芦商品瓜单瓜重、单瓜长和果实横径无显著影响(P>0.05),单株瓜数与对照相当或略有提高,以喷施5 mg/L瓜丰处理下产量最高,为67242.9 kg/hm^(2)。生长调节剂处理下商品瓜畸形率为21.1%~77.8%,均低于对照。灰色关联度分析表明,各指标与产量的关联度依次为:单株瓜数>内源脱落酸(ABA)>畸形率>果实横径>单瓜长>单瓜重>果实肉厚。【结论】使用生长调节剂有利于西葫芦商品瓜发育;采用浓度为5 mg/L瓜丰处理喷施西葫芦叶片,可减少化瓜、提高坐果率、显著增加产量。
【Objective】To study the effects of appearance traits,yield and quality of commercial melons of Cucubita pepo L.under different growth regulators.【Methods】"Qianhu No.2"as the test materials,and the leaves of Cucubita pepo L.were sprayed with different growth regulators(4,5,6,10 mg/L Guafeng and 1 mg/L Qianshou),and spraying water as a control,the effects of growth regulators on the appearance traits,yield and quality of commercial melons were analyzed,and the gray correlation method was used to analyze the correlation between each index and yield.【Results】The 1 mg/L Qianshou treatment significantly increased the single melon length and fruit transverse diameter of commercial melons of Cucubita pepo L.(P<0.01);the number of melons per plant was lower than that of the control,and the yield decreased.Guafeng treatment had no significant effect on the single melon weight,single melon length and fruit transverse diameter of commercial melons of Cucubita pepo L.(P>0.05),and the number of melons per plant was equal to or slightly increased compared to the control.5 mg/L Guafeng treatment had the highest yield(67242.9 kg/hm^(2)).The malformation rate of commercial melon under the treatment of growth regulator was 21.1%-77.8%,which was lower than that of the control.The gray correlation analysis showed that the correlation degree between each index and yield was as follows:the number of melons per plant>endogenous abscisic acid(ABA)>malformation rate>fruit transverse diameter>single melon length>single melon weight>fruit flesh thickness.【Conclusion】The use of growth regulators was beneficial to the development of commercial melons of Cucubita pepo L.;5 mg/L Guafeng treatment could reduce melons,increase fruit setting,and significantly increase yield.
