中文摘要 | 喜樹果皮厚的角質層和緊密排列的厚壁細胞組織,影響水分進出和種子發芽。未剝除果皮的果實其種子發芽率在播種4 wk後僅為15%,然剝皮能促進發芽,在播種2 wk後發芽率已達95%。剝除部分果皮有助於種子發芽,且以剝除胚根鄰近的果皮效果最佳。喜樹果實4℃層積濕藏3 mo後,無須人為剝皮,其種子發芽率即達80%,而後可維持此發芽率達6 mo,且平均發芽所需時間為14 d以內。低溫4℃層積濕藏不但能保存種子達9 mo之久,且可免除人為剝皮之困擾。喜樹果實低溫乾藏4 mo後仍有27%的發芽率,推測種子的儲藏性質可能為中間型,但有待進一步證實。 |
英文摘要 | The thick cuticle layer, and compact cells and tissues in the pericarp of Camptotheca acuminata Decaisne fruit affected water inflow and seed germination. After a 4-wk incubation, the germination percentage of seeds with pericarp was 15%. However, seed germination increased to 95% within 2 wk after the pericarp had been removed. Partial removal of the pericarp was able to improve the seed germination, and the highest germination was determined when the pericarp near the radicle was removed. Cold stratification of fruit at 4℃ for 3 mo increased seed germination to 80% as compared to fresh fruit, and this method retained seed viability for 9 mo. Because cold stratification caused the pericarp structure to disintegrate, with stratification, there was no need to remove the pericarp, and seed germination was promoted. The mean germination time was drastically shortened to less than 14 d by a 3-mo stratification period. Storing dehydrated fruits of C. acuminata at 4 or -20℃ retained 27% germination, we thus speculated that the seed is probably characterized as having an intermediate storage behavior. However, this needs to be further confirmed. |
