The Nursing Trials of Heritiera littoralis Seedings ZHENG Zhou-xiang,YE Xin-an,YAN Xiao-qing,LIU De-hao,CHEN Zhi-tao,PENG Yi-sheng 2017, 46(01): 76-82.  DOI: 10.3969/j.issn.1009-7791.2017.01.015 Abstract ( )   PDF (697KB) ( )   The influence of different sowing times, physical treatments of seeds, and interaction between salinity and inundation regime to the germination of Heritiera littoralis was explored. The durations of seed germination sowed in autumn-winter and early spring were longer than those in late spring and summer, while no significant difference of germination duration existed between seedlings sowed in April to June and July to September. Physical treatment on pericarps obviously affected germination time and rate, then affected their growth later. The germination time was shortened by entirely and partially shelled treatment. But germination rate of partially shelled treatment was 88.9%, which was significantly higher than that of entirely shelled as 74.4%. Moreover, the seedlings of entirely shelled treatment grew faster and more robust. Salinity and inundating frequency, also their interaction had strong impacts on seed germination of H. littoralis. Indicating irrigation with freshwater and reduction of inundation frequency may facilitate the germination of H. littoralis. Soluble saccharides and polyphenol were statistically lower in condition of lower salinity and inundating frequency. Since the germination state of H. littoralis were sensitive to temperature, it was recommended to carry out sowing in April to June after collection of mature capsule collected in the last autumn with dry-storing. Such measurement could effectively lower duration and cost of nursing, and reduce germination duration of seeds. References | Related Articles | Metrics
