三种油茶幼苗对低温胁迫的生理响应及其抗寒性综合评价
Comprehensive Evaluation of Physiological Responses to Low Temperature Stress and Cold Resistance of Three Species ofCamelliaSeedlings
摘要
Abstract
One-year-old seedlings ofCamellia oleifera,C. drupifera andC. semiserrata were used as experimental materials, and their physiological characteristics were investigated. The results showed that cholrophyll content and relative water content decreased, but the soluble protein content increased over time in threeCamellia species. After treatment for 72 h, the chlorophyll content and soluble protein were extremely significant difference compared to control inC. drupifera, and decreased by 64.67% and increased of 705.67%, respectively. While the chlorophyll content and soluble protein content inC. oleifera compared with the control only decreased of 34.35% and increased of 443.10%, showing stronger cold resistance. According to principal components analysis (PCA), It was described thatC. oleifera had the strongest resistance for cold stress, followed byC. semiserrataand C. drupifera.关键词
