摘要：室内模拟12个潮汐淹浸时间处理(2、4、6、8、10、12、14、16、18、20、22、24h·d-1)对红树植物白骨壤Avicennia marina小苗生长的影响,测定不同淹水时间处理下白骨壤小苗的叶绿素含量、根活力、生长量、生物量及净光合速率等10项生长信息指标.210d的试验结果表明,叶绿素含量、根活力、生物量及生长量均随淹水时间的延长先升后降,并在16h·d-1处出现骤变分界点,淹水时间超过16h·d-1后,白骨壤小苗的生物量、生长量均显著低于淹水时间<16h·d-1的处理;月均地茎增量、月均叶片增量、单株茎干重、单株根干重及总生物量均在淹水10h·d-1处理下最大.结合主成分分析得出结论,白骨壤小苗在淹水时间<16h·d-1的处理下均能正常生长,最适淹水时间为8～12h·d-1,临界淹水时间为16h·d-1.
A laboratory test on the effects of differents simulated tide-inundated times with 2,4,6,8,10,12,14,16,18,20,22, 24 h·d^-1 on the growth of Avicennia marina seedlings was conducted. The ten growth information indices including chlorophyll,root vigor,growth,biomass and photosynthetic rate were mensurated. The principal components analysis was made combining the ten growth information indices. The 210d experimental results showed that the chlorophyll,root vigor,growth and biomass would rise first and then fall as the extension of the inundate time; and they changed suddenly at the threshold inundate time 16 h·d^-1. The growth and biomass of Avicennia marina seedlings with more than 16 hours tide-inundated time per day were less than them with no more than 16 hours tide-inundated time per day. The maximum value of stem increment each month,leaf blade increment each month,dry weight of stem,dry weight of root and total biomass were under the 10 hours tide-inundated time per day. It concluded that Avicennia marina seedlings would grow adaptively with less than 16 hours tide-inundated time per day,8-12 hours of tide-inundated time per day is the most suitable for the growth of Avicennia marina seedlings,while 16 h·d^-1is a critical tide-inundated time when the plant responded to be obviously inadaptable.
