| 摘 要： | 通过对不同产量类型雷竹林植株及竹笋激素的分析,认为GA3和ABA调控着雷竹鞭侧芽的萌发,也就是影响着竹林的产量,而IAA和CTK对雷竹鞭侧芽的萌发没有明显的调控作用,但影响着竹笋的生长发育;通过对氨基酸含量的分析认为高、中、低雷竹林竹笋的氨基酸含量基本相同,但覆盖雷竹林的春季竹笋氨基酸含量明显下降;通过对竹笋营养成分的分析,得出蛋白质、N、P、K含量从高、中、低产林呈下降趋势,并还认为竹林中适当增施N肥有利于笋产量的提高。

| Abstract: | The content of endogenous hormones of bamboo and bamboo shoots of high,middle and low-yield bamboo forest was analyzed.The results showed that the germination of lateral buds on rhizomes and the yield of bamboo shoots were adjusted and controlled by GA3 and ABA,not by IAA and CTK,but IAA and CTK affected the growth and development of bamboo shoots.The content of amino acid of bamboo shoots from forests with different yield was about same.However,in ground-covered bamboo forest,the content of amino acid of spring bamboo shoots was lower than that of uncovered ones.In terms of the measurement on the nutrition of bamboo shoots,it was found that the content of protein,N,P decreased with the decrease of bamboo shoot yield.In addition,applying nitrogen fertilizer properly was beneficial to the increase of bamboo shoot yield. |
