红松苗的自身抑制模拟试验证明红松针叶粉及其针叶水浸出物对其光合速率、根系生理活性、菌根生长有很强的抑制作用,因而明显地降低其苗高、白根及全株生物量的生长。从而证明红松纯林下幼苗确实存在着自身抑制作用。对其机理有待进一步研究。
The self-inhibition simulation experiment of Korean pine seedlings proved that the Korean pine needles powder and its coniferous leaves extract had a strong inhibitory effect on its photosynthetic rate, physiological activity of root system and mycorrhizal growth, thus significantly reducing its height, white root and whole plant The growth of biomass. This proves that Pinus koraiensis pure seedlings do exist their own inhibition. The mechanism needs further study.
