Abstract

Using artificial sea water (8 g·kg-1 in salinity) as control treatment, the Aegiceras corniculatum seedlings were cultivated in fresh water with constant water level under full sun light for one year in Meizhou city, Guangdong to investigate the effect of fresh water on the growth and development of Aegiceras corniculatum seedlings. The result showed that the stem height, stem diameter, plumular axis diameter of the fresh water groups were significantly lower than those of the artificial sea water group,and the number of leaves of the fresh water groups were extra significantly less than that of the artificial sea water group; whereas no significant difference existed between two groups in such indexes as the plumular axis height, number of stem branches, leaf length, leaf width, ratio of leaf length to width, root length, root diameter and the number of roots cultivation; but the leaf area of the fresh water treatment was 18.11% higher than that of the artificial sea treatment, the differences had reached statistically significant level. At the 180th day, although the dry weight of root, stem and leaf and the total dry weight of fresh water treatment were respectively 12.50%, 18.40%, 16.48% and 16.32% lower than those of the artificial sea treatment, the differences had not reached statistically significant level; and both treatments demonstrated a trend of stem＞leaf＞root in biomass; At the 360th day, although the dry weight of root, stem and leaf and the total dry weight of fresh water treatment were respectively 33.88%,17.48%,28.30% and 26.51% lower than those of the artificial sea treatment, the differences had not reached statistically significcant level; and both treatments demonstrated a trend of leaf>stem>root in biomass. The 1-year-old seedling survival rates of both treatments were above 90%, and the seedlings in both treatments were able to flower, while the flowering date in fresh water treatment was 25 days later than the artificial sea treatment, but the former had 33.82% more flowering plants than that of the artificial treatment. In a conclusion, Aegiceras corniculatum seedlings could normally grow and flower in fresh water, although most of their morphological characteristics were significantly affected by fresh water.
