Abstract

Nuclear distribution and behaviour during vegetative growth and spore formation in Alternaria tenuis was studied utilising the HC1-Giemsa staining technique. The vegetative mycelium and conidia are predominantly monokaryotic. Anastomoses, followed by nuclear migrations, have been recorded. Intercellular nuclear migrations have only been observed in germinating conidia. Nuclear behaviour during conidial formation indicates that the conidia are homokaryotic. Cytological differences have been found in different monocoidal isolates of A. tenuis.

摘要

利用盐酸-吉姆萨染色技术研究了细交链孢菌营养生长和孢子形成过程中的核分布及行为。营养菌丝体和分生孢子主要为单核。已记录到菌丝融合,随后是核迁移。仅在萌发的分生孢子中观察到细胞间核迁移。分生孢子形成过程中的核行为表明分生孢子是同核的。在细交链孢菌不同的单孢分离株中发现了细胞学差异。
