不同遮阴栽培对金花茶叶片生理和药用品质的影响

    Effects of Different Shade Cultivations on the Physiology and Medicinal Quality of Golden Camellia Leaves

    • 摘要: 通过比较林缘、林间及遮阳网下不同遮阴栽培金花茶叶片的丙二醛(MDA)、脯氨酸(Pro)、可溶性糖(SS)、茶多酚、总黄酮、总皂苷和粗多糖的含量,及超氧化物歧化酶(SOD)、过氧化物酶(POD)的活性差异,探究不同遮阴栽培对其叶片抗逆相关生理和主要药用成分含量的影响。结果表明:林间及遮阳网下栽培有利于金花茶的正常生长,能降低其叶片抗逆生理反应,提高粗多糖含量,但林缘栽培能提高金花茶叶片茶多酚、总黄酮和总皂苷的含量。生产中可根据产品需求采用不同遮阴方式栽培,在保证金花茶正常生长前提下提高目标成分的产量。

       

      Abstract: By comparing the contents of malondialdehyde (MDA), proline (Pro), soluble sugar (SS), tea polyphenol, total flavonoids, total saponins and crude polysaccharide in the leaves of golden camellia at the edge of the forest, in the forest and under the shading nets, as well as the activity differences of superoxide dismutase (SOD) and peroxidase (POD), the effects of different shade cultivations on the stress-resistance physiology and the content of main medicinal components in the leaves were explored. The results showed that the cultivations in the forest and under the shading nets were conducive to the normal growth of golden camellia, which could reduce the stress-resistance physiological response of the leaves and increase the content of crude polysaccharide. However, the cultivation at the edge of the forest could improve the content of tea polyphenol, total flavonoids and total saponins in the leaves of golden camellia. In the production, different shade cultivations could be adopted according to the product demand in order to increase the yield of target compositions under the premise of ensuring the normal growth of golden camellia.
