通过对赣1号、宫川、奉新柑和遂川金柑等柑桔品种的叶片解剖特性观察、叶片自由水与束缚水含量和过氧化氢酶活性的测定,以及不同低温下其离体叶片的冻害症状研究,经综合比较分析,结果表明,赣1号的抗寒性比宫川、奉新柑强,但比遂川金柑弱。
The leaf anatomical characteristics of Gan-1, Gong-guan, Feng-xung-hyong and Suichuan-kumquat were observed, and the free and bound water content and catalase activity were measured. The results showed that the cold resistance of Gan-1 was stronger than that of Gong-chuan and Fengxin, but was weaker than that of Suichuan.
