不同脱蜡粉类型砧木对嫁接黄瓜生长及硅吸收分配特性的影响
EFFECTS OF DIFFERENT DE-BLOOM ROOTSTOCKS ON GROWTH AND SILICON DISTRIBUTION IN GRAFTED CUCUMBER
摘要
Abstract
To study the physiological mechanism of bloom on fruit surface of cucumber, and provide theory basis for breeding and high quality cultivation, rootstocks with significant different effects on bloom formation of grafted cucumber were used to investigate the influences on plant growth and silicon distribution. The results showed that; At fruiting stage, the plant height, leaf number and early yield of cucumber grafted on light -bloom root-stocks were lower than those grafted on heavy - bloom or medium - bloom rootstocks, but higher than own - root cucumber; There was more silicon in leaves than that stemin and roots of cucumber; the silicon levels in leaves and stem of cucumber grafted on light - bloom rootstocks were lower than that in those grafted on heavy - bloom or medium - bloom rootstocks, as well as on own - root cucumber; the roots of cucumber grafted on Yunnan fi-gleaf gourd'showed the highest silicon content; with the growth of fruits, the silicon content increased first, and then decreased; however, the silicon content in leaves gradually reduced; the silicon contents in fruits of cucumber grafted on light - bloom rootstocks were obviously lower than those grafted on heavy - bloom and medium -bloom rootstocks, as well as on own - root cucumber. Different bloom - type rootstocks affected the formation of fruit bloom, which was partly associated with the absorption and distribution of silicon.关键词
