【摘要】 对南方红豆杉扦插苗与实生苗根系、叶片若干生理代谢指标比较研究结果表明,南方红豆杉实生苗长势较扦插苗旺盛,根系活力及呼吸强度、叶片内源吲哚乙酸、绿原酸、N、P、K和粗蛋白质及游离氨基酸含量均高于扦插苗;而叶片吲哚乙酸氧化酶和过氧化物酶活性、脱落酸含量则低于扦插苗。更多还原

【Abstract】 Some indexes of the growth and metabolism of roots and leaves of cutting seedlings and seed seedlings of Taxus chinensis var.mairei were compared.The results show that the vigor and respiratory intensity of roots,the contents of endogenous indoleacetic acid(IAA),chlorogenic acid,nitrogen,phosphorus,potassium,protein and free amino acids of leaves of the seed seedlings are higher than those of the cutting seedlings;but activities of IAA,oxidase and peroxidase(POD)and the content of abscisic acid of leaves of the seedlings are lower than those of the cutting seedlings.The experimental results can provide a theoretical basis for a scale production of the cutting seedlings and the control of their nutrient level.更多还原
