三项比较试验结果表明,甜菜试管苗培养中有支持物比无支持物好,支持物选用聚氨酯海绵小块,不仅降低了成本,而且方便了使用。将20毫升培养液分装在50毫升的三角瓶内,转移培养三周的甜菜试管苗表现良好,平均每日叶片增长数比琼脂培养基提高0.45片。
The results of the three comparative experiments showed that the support of beet in vitro culture was better than that of no support and the support selected polyurethane sponge, which not only reduced the cost but also facilitated the use. The 20 ml culture medium was dispensed in a 50 ml Erlenmeyer flask and the test tube plantlets in the three-week transfer culture performed well. The average number of leaf growth per day was 0.45 piece higher than that of the agar medium.
