After 1 year , the survival rates of seedlings planted in k . candel forest , avicennia marina forest and at bare tidal flat were 54 . 7 % , 13 . 7 % and 76 . 0 % , respectively . insect and crab feeding were the main cause of lower survivorship of k . candel seedlings under a . marina forest . among the surviving k . candel seedlings , seedlings at bare tidal flat grew much better in terms of height , diameter , leaf production and biomass than did under the a . marina forest and k . candel forest 高盐( 30 % 0一50 % 0 )影响桐花树幼苗的萌发; o一30 % 0盐度下桐花树幼苗的净光合速率、蒸腾速率和气孔导度都表现为低盐促进，高盐抑制的变化趋势;无盐条件下幼苗的净光合速率明显低于5 ~加% 0盐度:桐花树胎生繁殖体脱离母树后，在随后的生长发育过程中表现为吸收累积盐分的过程。
The results showed that the net photosynthetic rates of the three hex species under full light were higher than those under 45 % of full light , which were higher than those under 20 % of light , and the diurnal net photosynthetic rates varied in a double - peak curve , which reflected that the three hex species were neutral tree species 结果表明： 3种冬青在全光照下的净光合速率高于透光率45 %下的，透光率45 %的高于透光率20 %的，且全光照处理的净光合速率日变化均为双峰曲线，反映3种冬青均为中性树种。
