摘要
应用湛江师范学院科技开发中心研制的新型植物调节剂,对西瓜进行了初步应用试验研究,结果表明喷施新型植物调节剂具有以下功效:(1)可以提高西瓜的单果重,其中以稀释100倍药剂效果最显著,在盛花期施用该浓度药剂,平均单果重比照提高了6.7%,幼果期1次用药平均单果重比对照提高12.9%,幼果期二用次药平均单果重比对照提高17.9%;幼果期喷药比盛花期喷药对果实单果重的提高更明显;(2)可以提高西瓜的可溶性固形物的百分含量,Tss比对照提高0.4～3.4,改善了果实的品质;(3)可以使西瓜的果柄普遍增粗,增粗幅度在47.8%～86.2%,对营养生长有促进作用;(4)可以促进西瓜不同程度的单性结实。
The plant growth regulator (GLD),which was prepared by Zhanjiang Normal College, was applied to watermelon for yields increasing and quality improving effect. The results showed that: (1) The average weight of per watermelon fruit could be increased by using GLD, and the effect of GLD [1:100] was most evident, treating once increasing by 6.67%.and twice by13.33%; (2) The percentage content of soluble solid substance in the fruit was heightened, treating once with GLD[1:100] increasing by 1.6%, twice by 3.00% .and the fruit quality was improved.(3) The fruit haft was thickened evidently by GLD. (4) The parthenocarpy of watermelon was inducible in some degree by GLD.
