查询词典 agar

The trials of adventive bud regeneration directly and callus induction was conducted to select out the optimal explants and formula. The results revealed that double scale can produce 13~16 adventive buds per centimeter in MS medium added 10.0 mg/L 6-BA, 1.0 mg/ L NAA, 40 g/L sugar and 7.5 g/L agar. Scale, leaves, scape and different tissue of flower can be induced to produce callus in appropriate medium, but the filament with anther was the optimized explant.

The minimum inhibitory concentration was determined by serial dilution in the same type of agar, with concentration ranging from 5, 10, 25, 50, 75 and 100 mg/ml.

最低抑菌浓度测定在同一类型的琼脂稀释系列不等，5，10，25，50，75和100毫克/毫升的浓度。

Additionally, the growth of the pathogen was obviously affected by cultural media. The morphological characters such as colony color and diameter, and production of fruit body of the fungus growing on PDA, 10% V8, apple leaves dextrose agar and apple leaves extraction dextrose agar media were different. The fungus formed colonies of about 8mm in diameter and did not produce fruit bodies and aerial hyphae in 1 month incubation on PDA. However it formed the similar size colonies as on PDA and produced fruit bodies and aerial hyphae on 10% V8 and LDA media in the same incubation period. Very small colonies (2mm in diameter) and fruit bodies were found on LEDA media in the same incubation condition. These results indicated that successful isolation of M. coronaria from apple leaves depended on suitable isolation method and cultural media as well as fresh samples.

不同培养基上菌落形态、大小和产孢情况差异也很大，培养1个月（25℃）后PDA上菌落黑褐色隆起，表面蚯蚓粪状，无气生菌丝，无子实体和基内菌丝；10% V8培养基上菌落中央隆起，黑褐色，表面生少量气生菌丝，边缘放射状，基内菌丝深褐色，有子实体；苹果叶片葡萄糖琼脂培养基上菌落平坦，黄褐色，表面生茂密的金黄色气生菌丝，基内菌丝深褐色，有子实体；苹果叶片煎汁葡萄糖琼脂培养基上菌落有明显的不规则隆起，黄褐色至黑褐色，表面生少许气生菌丝，菌落生长缓慢，无基内菌丝，分生孢子盘菌落表面生，菌落直径仅2mm左右，而在其他培养基上的菌落直径可达6－8mm，说明培养基质、分离方法均对苹果盘二孢的分离培养和生长发育有明显的影响。

The strain can normal growth using agar as the sole carbon source medium and after the growth of 4-5 days, agar massive was hydrolysised with the appearance of a great amount of holes.

该菌株在琼脂作为唯一碳源的培养基中能够正常生长，并在4-5天的生长后，琼脂上产生大量的水解坑，在培养15天左右整个琼脂都被液化。
