The study was undertaken to understand the effect of plant growth regulators (PGRs) on cormlet production in Hypoxis hemerocallidea corm cuttings. In the first experiment, conducted in spring and summer, whole corms and corms subjected to chipping into four or eight segments or to scooping were used. These were soaked in 1.0 g L− 1 indole-3-butyric acid (IBA), 0.5 g L− 1 α-naphthalene acetic acid (NAA), a combination of 1.0 g L− 1 IBA and 0.5 g L− 1 NAA, or distilled water (control) for 16 h. In the second experiment, corms cut by chipping into eight segments were soaked in 25, 50, or 100 mg L− 1 of 6-benzyladenine (BA) or gibberellic acid (GA3), as well as their combinations (100 mg L− 1 GA3 + 25 mg L− 1 BA, 100 mg L− 1 BA + 25 mg L− 1 GA3) for either 30, 60, or 120 min. Soaking corm cuttings chipped into equal segments in distilled water significantly increased the number of cormlets compared to soaking in IBA or NAA. Chipping into eight segments and soaking in distilled water resulted in a significantly higher number of cormlets in the summer experiment. There were no significant differences in the number of cormlets when the eight segments of corm cuttings were soaked in BA and GA3. Soaking the corm cuttings for 120 min in GA3 at 25 mg L− 1 resulted in all eight segments of the cuttings producing one cormlet each. This is the first report on vegetative propagation of H. hemerocallidea showing that PGRs' had no positive effect on cormlet production.

植物生长调节剂外源应用对球茎切割和外源施用响应的hypoxis hemerocallidea cormlet生产

该研究旨在了解植物生长调节剂 (PGR) 对 Hypoxis hemerocallidea 球茎插条中球茎生产的影响。在春季和夏季进行的第一个实验中,使用整个球茎和切成四或八段或舀出的球茎。将它们浸泡在 1.0 g L- 1 吲哚-3-丁酸 (IBA)、0.5 g L- 1 α-萘乙酸 (NAA)、1.0 g L- 1 IBA 和 0.5 g L- 1 NAA 的组合中,或蒸馏水(对照)16 小时。在第二个实验中,将切成八段的球茎浸泡在 25、50 或 100 mg L− 1 的 6-苄基腺嘌呤 (BA) 或赤霉酸 (GA3) 以及它们的组合 (100 mg L− 1 GA3 + 25 mg L− 1 BA,100 mg L− 1 BA + 25 mg L− 1 GA3) 30、60 或 120 分钟。与浸泡在 IBA 或 NAA 中相比,浸泡在蒸馏水中切成相等段的球茎切屑显着增加了球茎的数量。在夏季实验中,切成八段并浸泡在蒸馏水中会显着增加 Cormlets 的数量。将8段球茎插条浸泡在BA和GA3中,球茎数无显着差异。将球茎插条在 GA3 中以 25 mg L− 1 浸泡 120 分钟,导致插条的所有八个部分各产生一个小球茎。这是关于 H. hemerocallidea 营养繁殖的第一份报告,表明 PGR 对小球果生产没有积极影响。在夏季实验中,切成八段并浸泡在蒸馏水中会显着增加 Cormlets 的数量。将8段球茎插条浸泡在BA和GA3中,球茎数无显着差异。将球茎插条在 GA3 中以 25 mg L− 1 浸泡 120 分钟,导致插条的所有八个部分各产生一个小球茎。这是关于 H. hemerocallidea 营养繁殖的第一份报告,表明 PGR 对小球果生产没有积极影响。在夏季实验中,切成八段并浸泡在蒸馏水中会显着增加 Cormlets 的数量。将8段球茎插条浸泡在BA和GA3中,球茎数无显着差异。将球茎插条在 GA3 中以 25 mg L− 1 浸泡 120 分钟,导致插条的所有八个部分各产生一个小球茎。这是关于 H. hemerocallidea 营养繁殖的第一份报告,表明 PGR 对小球果生产没有积极影响。将球茎插条在 GA3 中以 25 mg L− 1 浸泡 120 分钟,导致插条的所有八个部分各产生一个小球茎。这是关于 H. hemerocallidea 营养繁殖的第一份报告,表明 PGR 对小球果生产没有积极影响。将球茎插条在 GA3 中以 25 mg L− 1 浸泡 120 分钟,导致插条的所有八个部分各产生一个小球茎。这是关于 H. hemerocallidea 营养繁殖的第一份报告,表明 PGR 对小球果生产没有积极影响。
