- Developing endosperm is of the nucellar type. In late July, mature seeds contain very less endosperm and a big embryo with 2 massive cotyledons,the hypocotyl and the radicle. 胚乳之发育为核型。约在7月下旬,成熟种子只具有非常微量之胚乳,以及两枚子叶、胚轴及胚根。
- The results showed that if it was not long time that seedbed was waterlogged,the germination rate of mature seeds could be up to 71%,and the premature seeds must be abandoned. 结果表明:乐昌含笑在播种繁殖时,完全成熟种子出苗率可达71%25以上,种子切忌掠青,同时,圃地积水时间不宜太长;
- Under microscopic observation, the small cell groups grew into ovules at 43 DAP, and the ovules began elongating.The ovules became mature seeds gradually at 99 DAP. 在显微镜下观察发现,胎座末端的小细胞团分裂生长至受粉后43天具有胚珠的外型,之后胚珠开始延长,在受粉后99天逐渐形成成熟种子。
- PEG could significantly improve the germination energy of alder seed, with its extent relating to the maturity level of seed, no effect of PEG was found on the relative higher maturity seed of alder. PEG能显著提高桤木种子的发芽势,提高发芽率的效用与种子的成熟度有关,对成熟度高的种子影响不显著;
- The results showed that high concentration of 2,4-D was required for callus induction from mature seeds of tall fescue, and combination of 8mg/L 2,4-D with 2mg/L ABA gave best induction effects. 研究表明,高羊茅成熟种子愈伤组织诱导需要较高浓度的2,4-D,以8mg/L 2,4-D与2mg/L ABA配合能获得最佳的诱导效果;
- The concept of critical moisture content is discussed and the safest moisture content for keeping the viability of recalcitrant seeds is that of mature seeds or even higher in moisture content. 我们也探讨了临界含水率之观念,并认为保持成熟种子之含水率甚至更高之含水率是保存异储型种子活力最安全的做法。
