摘要

木树(Xylocarpus mekongensis Pierre)是孙德尔本斯地区的重要树种。本研究旨在探讨盐度对绿尾松幼苗存活和生长的影响。研究了幼苗部位氮、磷、钾、钠、碳的分布规律与盐度的关系。在无盐至微盐(0-5 PSU)条件下,幼苗存活率较高(95%),在35 PSU盐度下,存活率降至78%。相对生长率(RGR)在无盐至微盐(0 ~ 5 PSU)条件下高于高盐条件。发现营养物、钠和碳浓度变化显著(p . X. mekongensis具有耐受高盐条件的能力,但它们在无盐到低盐条件下生长良好。

Salt Tolerance of Xylocarpus mekongensis Pierre: Survival and Growth of Seedlings, Nutrients and Carbon Distribution in Seedling Parts
Xylocarpus mekongensis Pierre is the important tree species of the Sundarbans. The present study was conducted to evaluate the effect of salinity on the survival and growth of X. mekongensis seedlings. The distributional patterns of nitrogen, phosphorus, potassium, sodium, and carbon in seedling parts were also examined in relation to salinity. Comparatively higher survival (95%) of seedlings was observed at non-saline to slightly saline conditions (0-5 PSU) and it was decreased to 78% at 35 PSU salinity. The relative growth rate (RGR) was higher at non-saline to slightly saline (0 to 5 PSU) conditions compared to higher salinity. Nutrients, sodium, and carbon concentration are found to vary significantly (p X. mekongensis has the capacity to tolerate higher saline condition but they grow well in non-saline to less saline conditions.
