Provenance Selection of Aleurites montana Based on Endogenous Hormone
The seeds of 11 Aleurites Montana provenances in Fujian Province were collected and applied to the field experiments by randomized block designs in Jiaoxi Forestry Farm,Jianyang,Fujian.12 blocks with 11 sample plots in each block were designed and 25 stocks were planted in each sample plot which covered 100 m2.The stock height and root collar diameter of 2-year-old seedlings were measured.GA3,ZR,IAA,ABA in the foliage of the provenances were determined by ELISA and provenance selection was conducted based on projected values of the endogenous hormone by the modified projection pursuit method.The results showed that in terms of the integrated effects of endogenous hormone,Putian and Zhenghe provenances dominated,followed by Zhouning,Youxi,Jianyang,Pingnan,Shaxian,Fuding,Zherong,Jiaocheng and Fu'an provenances.The combination of endogenous hormone with seedling growth provided some theoretical and practical references for the early selection of provenances.
