  • Promotion of germination of Euonymus oxyphyllus Miq. and E. planipes Koehne seeds by cold stratification and gibberellic acid (GA3) treatment  [in Japanese]

    SHINOZAKI Takaya , FUKUNAGA Kenji

    ニシキギ属の落葉低木類の種子は強い休眠性を持つものが多く,発芽が不揃いになりやすい。そこで,含水率を31.8 %,27.2 %に低下させた同属のツリバナ,オオツリバナ種子に対する低温湿層処理とジベレリン処理の発芽促進効果を検討した。その結果,変温環境下の屋外の発芽試験では,2樹種ともジベレリン未処理のものは発芽ピークまでに50日間要したのに対し,処理を行ったものは20日前後に短縮された。また,ジベ …

    … One time immersion treatment of the adequately thinned flower clusters with 100 ppm GA3 at around full bloom, however, resulted in the formation of large-sized black berries of 8-11 g that stuck together. … However, once the flower cluster thinning was carried out so that the each of the clusters had about 70 flowers, fruit thinning was unnecessary because of ideal fruit set and growth rates after the GA3 treatment of the thinned flower clusters. …

    … Fruit set in non-treated clusters was observed in 78.3% of the hybrids, whereas GA_3 treatment of the clusters resulted in fruit set in all the hybrids. … In almost all hybrids that set fruits without GA_3 treatment, GA_3 treatment to the flower clusters increased not only berry weight but also the berry set rates, especially in those setting small number of berries without GA3 treatment. …
