Abstract:
Taking plantlets in vitro of Anoectochilus roxburghii as test materials,the effect of different light intensity on the growth and yield were studied by three factors of survival rate,growth rate of fresh weight and DW/FW.The results showed that,light intensity had significant effect on the three factors,the lower middle light intensity in 2 000-5 000 lx ranges was suitable for normal growth of plantlets to obtain high yield,and an appropriate increase in this range of light intensity was beneficial to the accumulation of dry matter.Low light intensity seriously reduced growth and dry matter accumulation of plantlets,high light intensity seriously reduced the survival rate of plantlets.
