摘 要 ：将海南琼山、廉江高桥、福建龙海及深圳福田本地的秋茄胚轴 ,培育在深圳福田相同生境中 ,一年以后 ,幼苗的形态生长呈现极显著差异性 ,琼山和福田本地秋茄种源生长最好 ,龙海种源生长最差。生理生态指标值如含水量、叶绿素总量、过氧化氢酶活性、游离脯氨酸含量、电导率等 ,以本地种源最高 ;而植株分枝数、叶片数量及光合速率、蒸腾速率、气孔导度等指标值 ,以琼山种源最高 ,龙海和高桥种源的较低。应用坐标综合评定法 ,初步认为福田本地秋茄是最优种源。

Abstract:Kandelia candel(D.)is a woody mangrove species growing in intertidal of tropical and subtropical region.It naturally distributed in 5 southeastern provinces (Hainan,Guangdong,Guangxi,Taiwan and Fujian) of China.The distribution,however,has been shrinking due to over exploitation of its habitat.Rehabilitating mangrove vegetation underwent in Shenzhen Bay,a place neighboring Hong Kong in Guangdong Province. K.candel propagated through hypocotyls.Replanting efforts demanded proper provenance.Based upon our ex...
