Studies on cutting propagation of Taxus chinensis var. maireiⅧ. Comparison of physiological metabolism between the seed seedlings and the cutting seedlings

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.
