摘要
通过不同低温对台湾引进的珍珠番石榴、无籽番石榴及福建省乡土番石榴的处理 ,测定其在低温胁迫下叶片若干生理生化变化 ,以探求番石榴不同品种的抗寒性与忍受的临界低温。结果表明 ,番石榴忍受的临界低温为 -3～ -4℃ ,因品种和低温持续时间而异。番石榴不同品种间耐寒性差异与叶片束缚水 自由水比值以及可溶性蛋白质、可溶性糖含量相关。乡土番石榴的抗寒性高于从台湾引进的两个品种。
By means of the stress of different low temperatures for the pearl Guava and seedless Guava, both introduced from Taiwan, and the native Guava in Fujian province, several physio-biochemical changes of their leaves have been determined under the low-temperature stress to seek the cold resistance and bearable critical low temperature of different Guava varieties. The results showed that the bearable low temperature of Guava was -3～-4℃, the cold resistance of different varieties was different and the differenc...
