| Abstract: | To study the low temperature tolerance of four palm species,the electrical conductivity,the ratio of free water/bound water,the chlorophyll contents and the ratio of chlorophyll a/b of their leaves were measured during winter(from 2004 Oct.to 2005 Jan.)in Xiamen City.The results showed that the low temperature tolerance from high to low are as follows: Phoenix canariensis>Chrysalidocarpus lucubensis>Trachycarpus martianus>Elaeis guineensis.Ch,3 tab.14 tab.] |
