摘要: 五年生葡萄柚實生苗在花芽分化前採用不同濃度益收(Ethrel)和亞拉(Alar)生長素處理,發現該兩種藥劑對葡萄柚新梢長度及節間長度均有抑制效果。益收1250ppm濃度及亞拉1175ppm濃度液並能增加結果枝數,亞拉1175ppm液並有減少幼果脫落效應,因此該兩種化學藥劑對縮短葡萄柚實生苗幼年期有所幫助。
Vigorous 5-year old grapefruit seedling were treated before flower-bud initiation with ethrel and SADH at different rates. Terminal growth and internode length were reduced effectively at rates of Ethrel 1250 ppm and SADH 1175 ppm. Ethrel at rate of 1175 ppm was effective in controlling young fruit abortion. This research work was helpful in the shortening juvenility on the grapefruit seedling.
