The Impact of the Plant Growth Regulator on the Growth of Seedlings of Camellia reticulate 'Xiaomi'
In order to research the impact of the plant growth regulator on the growth of seedlings of Camellia reticu-late'Xiaomi'and optimal dosage.This paper discussed plant growth regulator study which is wider application in C.reticulate'Xiaomi',use 3×3 regression of GA3 and IAA two factors.Choose a different concentration of GA3,IAA and its combination to alpine of C.reticulate'Xiaomi'grafting seedlings.Exclude the impact of the initial value after the data obtained through the covariance analysis prove:(1)Optimal concentrations of very significant promoting effect on the height of 5 mg/L GA3 and 5 mg/L IAA in 9 different combinations,34.4%higher of its handling than the non-application of plant growth regulators.(2)Ground diameter very significant promoting effect concentration combina-tion of 10 mg/L GA3 and 5 mg/L IAA is 24.6%higher than the control.(3)In 9 kinds of portfolio,all processing has very significant promoting effect on the crown,the optimal concentration combination is 0 mg/L GA3 and IAA 5 mg/L,26.1%higher than the control.The results show that,Application of GA3(10 mg/L)and IAA(0 mg/L or 5 mg/L)can promote Yunnan alpine C.reticulate'Xiaomi'grafted seedlings'height,ground diameter and crown growth.
