一种增脂剂对云南松增脂效果及生理活性的影响

Effect of a Tapping Irritant Agent on Oleoresin Yield and Physiological Indexes of Pinus yunnanensis Franch.

本研究将一种营养型增脂剂施用于云南松,检测其增脂效果及其对松针生理指标的影响,结果表明:5~10月份施加增脂剂后,云南松增脂率最高可达41.08%,平均增脂率34.76%。云南松松针鲜质量、干质量、叶绿素总量和可溶性蛋白均有所增加,最高分别可增加11.02%、10.26%、13.03%和40.96%;松针细胞三大保护酶超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性也有所增加,从而增加了云南松的抗逆性;松针中丙二醛(MDA)含量和相对电导率减少,增加了细胞内膜系统的稳定性,提高云南松抵御逆境的能力。

In order to improve the tapping yield of Pinus yunnanensis oleoresin,a nutritional tapping irritant agent was used.The efficiency of the agent and the influence of it to the physiological indexes of P.yunnanensis needles were investigated.The results showed that the maximum tapping yield increase reached to 41.08%with an average increase rate of 34.76%.The wet weight,dry weight,total chlorophyll content and soluble protein content of P.yunnanensis needle increased by 11.02%,10.26%,13.03%and 40.96%,respectively.The contents of superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)in the needle cells of P.yunnanensis also increased,which increased the resistance of P.yunnanensis.The content of malondialdehyde(MDA)and the relative electrical conductivity in pine needles decreased,which increased the stability of endomembrane system and enhanced the ability of P.yunnanensis to resist adversity.
