摘要:

研究不同油茶品种果皮花青素含量、糖含量和PAL酶活性与油茶炭疽病抗性关系。结果表明:花青素含量与油茶炭疽病的抗病性呈显著的正相关关系;可溶性总糖含量和PAL酶活性与油茶炭疽病发病率呈显著的负相关关系;花青素与可溶性总糖含量、PAL酶活性呈显著线性正相关关系。在油茶抗炭疽病品种选育中,果皮颜色(花青素含量)、可溶性总糖含量和PAL酶活性可作为抗性参考指标。

Abstract:

The relationship of anthocyanidin content, sugar content, PAL activity in oil-tea tree peel and the resistance to Colletotrichum gloeosporioides were studied in this paper. The results showed that anthocyanidin content are positive related with the disease resistance; the total soluble sugar content and PAL activity are negatively related with the incidence of C.gloeosporioides, The color of peel (content of anthocyanidin),total soluble sugar and PAL activity can be taken as an index of resistance to C.gloeosporioides for the seed selection and breeding in future.

Key words: Camellia oleifera, Colletotrichum gloeosporioides, anthocyanidin, PAL, total soluble sugar
