Effects of Different Cultivation Substrates and Hormones on Growth, Physiology and Biochemistry of Carallia brachiata

The effects of different cultivation substrates and hormones on growth of Carallia brachiata seedlings, physiological and biochemical indexes of leaf were studied. The results showed that it had significant difference in the ground diameter growth of seedlings, chlorophyll b and membrane permeability of leaf between two cultivation substrates. It had highly significant difference in the ground diameters growth and membrane permeability of leaf among different hormones, whereas insignificant difference in seedlings height growth, chlorophyll a, chlorophyll b and total chlorophyll. Taking 60% yellow soil and 40% pond sludge as cultivation medium was beneficial to ground diameters, height growth of C. brachiata seedlings. Taking 30% yellow soil and 30% mushroom residue and 40% pond sludge as cultivation medium was more favorable for chlorophyll and membrane permeability. The seedling height growth was highest by using IBA 100 mg·L-1 dipping the root. While dipping root by IBA 100 mg·L-1+NAA 50 mg·L-1 was beneficial to seedling ground diameter and membrane permeability.
