冬季自然低温胁迫对茶树抗寒生理指标的影响
Effects of winter low temperature stress on cold resistant physiological indices of Camellia sinensis (L.) O.Kuntze
摘要
Abstract
To study the effects of winter low temperature stress on cold resistant physiological indices, Camellia sinensis cv. Wuniuzao & Shuchazao were selected to determine the relative electric conductivity, MDA content and proline of leaves in the field under natural conditions during winter. The results showed that the average temperature of one day in Hefei fell from 18"C to 2'C during October to December, and then rose from 2°C to 16°C in December to April. The relative electric conductivity became lower at the beginning of stressing and higher later on .The contents of MDA were reduced before January 1st, and then were increased thereafter. But from Januray 20 to March 28th, the values became decreasing. The proline was decreased before December 30th, and then increased slowly with the stress. Almost no significant difference was found between the two tea cultivars. The slow decline in temperature in autumn accelerated the cold acclimation and promoted the cold hardiness resistance in tea plants.关键词
