摘要: 为探究百合茎尖培养及鳞茎繁育的影响因素,以百合罗宾娜组培苗为试验材料,进行了茎尖培养和瓶内养球研究。结果表明:茎尖大小是影响茎尖成活率的关键因素,1.0 mm茎尖成活率比0.5 mm茎尖成活率提高5%左右;提高植物生长调节剂和香蕉粉的含量可以提高茎尖成活率;光培养(12 h·d-1)比暗培养更有利于鳞茎增殖和生长,20 ℃和25 ℃对鳞茎生长的影响无明显差异;在25 ℃时,与暗培养相比,光培养获得的鳞茎数量、直径、鲜重、干重分别提高36.36%、15.33%、59.91%和44.74%。百合罗宾娜茎尖培养可选择1/2 MS(基本培养基)+0.5 mg·L-16-BA(6-苄基腺嘌呤)+0.2 mg·L-1 NAA(萘乙酸)+5.0 g·L-1香蕉粉培养基接种茎尖,直接光培养;鳞茎的培养条件可选择25 ℃,光培养。

Abstract:

In order to explore the influencing factors on stem tip culture and bulb propagation of lily, the tissue culture seedlings of lily Robina were selected as experimental materials, and the study was conducted through stem tip culture and culture of bulbs in bottles. The results showed that the size of the stem tip is a key factor affecting the survival rate of the stem tip. The survival rate of the 1.0 mm stem tip was about 5 percentage points higher than that of the 0.5 mm stem tip. Increasing the content of plant growth regulators and banana powder can improve the survival rate of the stem tip. Light culture (12 h·d-1) was more conducive to bulb proliferation and growth than dark culture, and there was almost no obvious difference in the effect of 20 ℃ and 25 ℃ on bulb growth. Compared with dark culture, the number, diameter, fresh weight, and dry weight of bulbs obtained under light culture at 25 ℃ increased by 36.36%,15.33%,59.91% and 44.74%, respectively. The stem tip culture of lily Robina can be carried out by inoculating the stem tips with 1/2 MS+0.5 mg·L-1 6-BA+0.2 mg·L-1 NAA+5.0 g·L-1 banana powder medium and directly culturing under light, and the cultivation conditions for bulbs can be selected as 25 ℃ and light cultivation.
