pteris 中文意思是什麼
pteris
解釋
鳳尾蕨屬-
The direct seeding experiments of different pteris vittata genotypes showed that there was significant difference in germination and emergence traits among pteris vittata genotypes collected from different areas in china, with germinating time ranging from 12 - 40 days, duration from germination to emergence varying between 13 - 46 days. as the seeds of pteris vittata are very small, with little stored nutrition, the genotypes, which are quick in germination and emergence, are suitable for direct seeding in the field
不同基因型的蜈蚣草的直接播種試驗研究表明，來自我國不同地區的蜈蚣草基因型在萌發特性有顯著差異，萌發時間變動在12 - 40d之間，萌發到成苗時間變化在13 - 46d 。因為蜈蚣草種子小，貯藏的營養物質少，故具有快速萌發和成苗特性的基因型易於田間直接育苗。 -
