Breaking dormancy and promotion of flowering in horticultural plants with volatile sulfur-containing substances in garlic and wasabi.

研究了二硫化甲酯、二硫化烯丙酯和异硫氰酸烯丙酯的最佳浓度。结果表明，1%为最佳。最佳处理温度为20℃，处理时间为2 ~ 6 h。通过这种方法，打破休眠的时间比未处理的对照组提前20-40%。二硫化甲酯对植物无毒，且开花时间加快。在12月前次生花茎开花困难的剑兰中，二硫化甲酯能促进其开花。因此，与未经处理的对照相比，切花总数达到六倍。可能，贮藏在球茎中的食物在二硫化甲处理下被迅速转运。这种化学物质促进了樱桃和牡丹的开花，随后加速发芽。二硫甲基处理增强了呼吸作用，正如乙烯处理中发现的那样。此外，球茎中的启动子增加，抑制子减少。这种现象与促进发芽和开花密切相关。因此，二甲基硫化物处理似乎对芽发芽有效，并导致在12月装运切花时促进开花。

An optimum concentration of methyl disulfide, allyl disufide and allyl isothiocyanate for breaking dormancy was studied. In result, 1% was optimum. Optimum treatment temperature was 20ﾟC and the duration was '2-6 hours. By this method, breaking dormancy was accelerated to 20-40% erlier than untreated control. Methyl disulfide did not induce phytotoxicity and flowering time was accelerated. In gladiolus in which flowering of secondary flower stems is difficult bv December in forcing, methyl disulfide promoted the flowering. Thus, total numbers of cut flowers amounted to sixfold compared to that of untreated control. Probably, storage food in the corms was quickly translocated by the methy disulfide treatment. This chemical promoted flowering of cherry and tree peony, folloewd by acceleration of sprouting. Methyl disulfide treatment enhanced respiration as found in ethylene treatment. Also, promotors in the corms increased and inhibitors decreased by the treatment. This phenomenon closely related to promotion of sprouting and flowering. Thus, dimethyl sulfide treatment seems effective on bud sprouting and resulted in Promotion of flowering in time of December shipping of cut flowers.
