摘要
通过叶绿素相对含量、POD酶活性和电导率测定 ,对毛华菊、南京 3、京 11、北林红、红十月 5个小菊品种 (或种 )的耐热性进行了鉴定。结果表明 ,随着热处理时间延长 ,毛华菊叶片叶绿素下降速度最小、电导率上升最慢、POD酶活性表现最高 ,是一最耐热的种类 ;其次是南京 3 ;耐热性最差的是京 11;红十月和北林红的耐热性介于毛华菊与京
Relative chlorophyll content,POD activity and electric conductivity were measured to determine the heat tolerance of five chrysanthemum cultivars or species with small flowers,namely, Ch. vestitum, Ch. morifolium cultivars 'Nanjing 3', 'Jing 11', 'Beilinghong' and 'Hongshiyue'. The results showed that Ch. vestitum is the best heat tolerant chrysanthemum showing least fall in chlorophyll content, highest POD activity and slowest rise in electric conductivity with the prolongation of heat treatment time; 'Jing11' is the worst heat tolerant cultivar, 'Nanjing3', 'Hongshiyue' and 'Beilinghong' are arranged between them in order of heat tolerance.
