Effect of Different Growth Promoters on Seedling Growth of Taxus Chinensis
This study investigated the effects of gibberellin(GA3),indoacetate(IAA)and Brassinolide(BR)on the growth of Taxus seedlings.The results showed that different concentrations of GA3,IAA and BR promoted the growth of Taxus seedlings.Among them,when the GA3 concentration is 100 mg/L,the stem elongation is 12.5cm,at the IAA concentration is 10 mg/L,the root system is the longest,reaching 9.6cm;at the BR concentration is 0.1 mg/L,the chlorophyll content is the highest at 0.35mg/g.Meanwhile,GA3,IAA and BR also had some effects on the seedling biomass and nitrogen,phosphorus and potassium element content of Taxus chinensis.Con-sidering various factors,the yew seedlings grew best at 100 mg/L GA3,10 IAA 10 mg/L and BR 0.1 mg/L.This study provides theoreti-cal and practical guidance to further understand the effects of different growth promoters on seedling growth of R.chinensis.
