项目摘要

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.

研究了甲基二硫、烯丙基二硫和异硫氰酸烯丙酯打破休眠的最佳浓度。结果表明，1%为最佳。最佳处理温度为20 ℃，处理时间为2-6小时。用这种方法打破休眠比对照提高20-40%。甲基二硫没有诱导植物毒性和开花时间加快。在12月催花较困难的唐菖蒲中，甲基二硫促进了其开花。因此，与未处理的对照相比，切花的总数达到六倍。可能是由于甲基二硫处理使球茎中的贮藏食物迅速转移。这种化学物质促进了樱桃和牡丹的开花，随后促进了发芽。甲基二硫醚处理增强呼吸，发现在乙烯处理。此外，在球茎中的促进剂增加和抑制剂减少的处理。这一现象与促进发芽开花密切相关。因此，二甲基硫醚处理似乎对芽萌发有效，并导致在12月切花装运时促进开花。
