双核体

这样的双核体显然不能独立于单倍体阶段而存在。

Such a dikaryon cannot apparently exist independently of the haploid phase .

张家界野生菌株经过原生质体再生双核体分离可得以驯化。

Application of protoplast technique was in Zhangjiajie wild strain for the fruitful cultivation .

夏孢子是双核菌丝体产生的成堆的双核孢子，革质，椭圆形或卵圆形，密生短刺萌发后，一般从气孔侵入寄主。

Urediniospores are piles of dual-core spores produced by dual-core mycelium with leathery , oval-shaped or oval , dense and short thorn , and normally invade host plants from the stomata after germination .

本研究认为锈菌冬孢子可能也会在寄主表面萌发产生一个生长的短芽管，继续萌发产生双核菌丝体形成夏孢子，夏孢子萌发继续反复侵染寄主植物。

This study suggests that in the host surface teliospore may also produce a short germ tube , continue to produce dual-core mycelium which germinated to form urediniospores , then urediniospores germinate and infect host plants repeatedly .

研究了利用珍稀食用菌茶树菇双核菌丝进行原生质体分离和再生，以及原生质体单核菌株的筛选过程。

The preparation of monokaryon protoplasts and the screening of protoplast-derived monokaryon strains are important parts in mushroom research and breeding .

第3阶段，滤泡细胞包围卵母细胞后成为双核的柱状体；

The oocyte is surrounded by the follicular cells which form a single-layer and then the follicular cells become columnar shape with two nucleus .
