| 摘 要： | 竹类植物开花较罕见 ,对其开花的原因也有不同的学说 ,如病理学说、营养学说、周期学说、个体变异和突变学说、气候学说等 (毛高喜等 ,1996 ;周芳纯 ,1998) ,但有学者认为内源激素对植物的开花有一定的调节作用 (王锋 ,1990 ;梁武元等 ,1986 ;王白坡等 ,1999;马国华等 ,1995 ;王彦清等 ,1998;陆军等 ,1993)。根据植物生长习性 ,开花植物有 2种不同衰老方式。其中一类是一生中只开一次花 ,即在开花结实后整株植株就衰老死亡 ,这类植物称为单稔植物 ,竹类植物就属于这一类植物。植物内源激素是体内十分重要的活性物质 ,它参与并调整植物的新陈…

| Abstract: | The test site was located in Jincheng Town, Lin'an City, Zhejiang Province. The leaves, culms and rhizomes of two-year-old and three-year-old flowering individuals or non_flowering individuals were taken from the same bamboo (Phyllostachys praecox f. prevernalis) forest. The culms and rhizomes of one-year-old flowering or non_flowering were also taken from the same bamboo forest. Based on analysis of the content of endogenous hormones, amino_acid and nutrition in flowering stage of bamboo, the results showed that abscisic acid(ABA) had main effect on accelerating its flowering and the increase of cytokinin(CTK) was also one reason for bringing flower, but indole_3_acetic acid(IAA)antagonized on its flowering. Total amino-acid in the non_flowering bamboo was 23.01% higher than that in flowering bamboo. Aspartic acid (ASP) could delay flowering. Protein, especially protein in leaves had main effect on senescence procedure. Increase of phosphorus content in flowering bamboo could accelerate metabolizing, and therefore promote senescence of bamboo. |
