Abstract

<p>オオシラビソの種子に対する水選の有効性を検証し,休眠を打破するために必要な低温湿層処理の期間を調べた。無処理の種子の充実率が28.7%であったのに対し,水選後は74.7~84.7%と有意に増加した。したがって,水を使用した比重選は同種の種子充実率を簡易に向上させることが示された。低温湿層処理を施した場合と無処理との発芽率を水選した種子を用いて比較した結果,前者の発芽率は75.0~84.7%となり,後者の場合(18.3%)に比べて有意に高まった。処理期間の長短で最終発芽率に統計的な違いはなく,30日間の低温湿層処理でも7割以上の種子が発芽した。</p>

<p>We examined the effectiveness of seed selection based on the specific gravity of water and the duration of moist chilling treatment required to break seed dormancy in<i> Abies mariesii</i>. The proportion of filled seeds significantly increased 74.7-84.7% after specific gravity-based selection using water compared to the proportion of untreated seeds (28.7%). Therefore, our study indicates that seed selection using specific gravity of water can easily improve the seed filling rate of <i>Abies mariesii</i>. The germination rate between seeds in the moist chilling treatment and non-treatment were compared. The results showed that the germination rate of the former was 75.0-84.7%, which was significantly higher than the latter (18.3%). The duration of the moist chilling treatment showed no statistical difference in the final germination rate, and more than 70% of the seeds germinated even after 30 days of moist chilling treatment.</p>
