以珠芽黄魔芋(Amorphophallus konjac K.Koch)2个量级球茎为供试材料,采用喷施不同浓度梯度生长素和赤霉素等体积混合溶液,以及光照、自然阴干、花芽分化后和分化前埋入基质中的技术手段,探究人工诱导珠芽黄魔芋开花结子的方法。结果表... 以珠芽黄魔芋(Amorphophallus konjac K.Koch)2个量级球茎为供试材料,采用喷施不同浓度梯度生长素和赤霉素等体积混合溶液,以及光照、自然阴干、花芽分化后和分化前埋入基质中的技术手段,探究人工诱导珠芽黄魔芋开花结子的方法。结果表明,2.0 kg及以上球茎的开花率均要高于1.0~1.5 kg的球茎,最高的开花率达93.33%;2.0 kg及以上球茎在光照处理条件下,生长调节剂浓度配比为1∶1 200,花芽分化后埋入基质中的结子率最高,达81.11%;2.0 kg及以上球茎在自然阴干处理条件下,生长调节剂浓度配比为1∶800,花芽分化后埋入基质中的种子数量最多,达4 442粒,繁殖倍数将近300倍。2.0 kg及以上的球茎,生长调节剂浓度配比为1∶400~1∶1 200,花芽分化后埋入基质中的方法可在生产实践中推广应用。 展开更多

[Objective] The aim was to research annual shoot increments, blooming and fruit-bearing times, and sprouting ratio of man-made Phoebe boumei.[Methed] Phenological observations of Phoebe boumei blooming were conducted as per method of phytocoenology. [Result] Phoebe bournei shot three times per year, and autumn shoots proved the largest, followed by summer shoots and spring sprouts. Sprouts shaped from late April to early May, and bloomed from late April to middle May; young fruits grew from middle May to late May and matured from middle De- cember to late December. Thousand-seed weight of fruits reached 487-503 g, and averaged 496 g; thousand-seed weight of seed was 265-275 g and averaged 269 g; sprouting rate of seed in room was in 84.8%-88.5% and averaged 86.5%; sprouting rate of seeds in fields was in 68.4%-72.6%, and averaged 70.4%. [Conclusion] The research provides references for man-made Phoebe bournei forests. 展开更多
