摘要

During the two-year period (1993-1994), the following Fusarium species with different frequencies were isolated in soil, maize root and stalk. F. solani, F. equiseti, F. moniliforme, F. oxysporum, F. sybglutinans, F. graminearum, F. culmorum, F. sporotrichioides, F. tricinctum, F. crookwellense and F. proliferation. F proliferation was for the first time isolated in Yugoslavia in 1993. The purpose of this study was to describe in detail this newly discovered Fusarium species, to determine whether itwas saprophytic or parasitic importance for maize and to ascertain whether maize inbred lines were susceptible to the pathogens or not. At the same time, the study also included F. monilifonne, as it is very distributed species of known pathogenicity and similar properties to F. proliferatum. F. proliferatum and F. monilifonne produced microconidia in short chains on polyphialides and long or short chains on monophialides, respectively. The first one formed a little white "tufts" on PDA and CLA media,while the later did not. F. proliferatum frequency was higher in soil, while the frequency of F. monilifonne was higher in maize root and stalk. Both species were more distributed in root than in stalk and were patogenic to maize seedlings, especially isolates of F. moniliforme, causing tissue necrosis of root and hypocotyl growth. The two isolates out of all F. proliferatum isolates, pr23 and pr26, were of the highest and the lowest virulence, respectively. Susceptibility of maize inbred lines to studied fungi and different isolates of one fungus was different. Obtained results point out that F. proliferatum is significant maize pathogenic species and can cause serious necroses and even decay of seedlings.

F增殖是1993年在南斯拉夫首次分离。本研究的目的是详细描述这种新发现的镰刀菌种，以确定其对玉米是腐生性还是寄生性，并确定玉米近交系是否易感。病原与否。同时，该研究还包括F. monilifonne，因为它是分布广泛的物种，具有已知的致病性和与F. proliferatum相似的特性。 F. proliferatum和F. monilifonne分别在多phialides的短链和单phialides的长链或短链中产生了微型分生孢子。第一个在PDA和CLA介质上形成了一个白色的“簇状”，而第二个则没有。土壤中F. proliferatum频率较高，而玉米根和茎中F. monilifonne频率较高。两种植物在根部的分布都比在茎中的分布更广，并且对玉米幼苗，特别是念珠状镰孢的分离株有光生性，导致根部组织坏死和下胚轴生长。在所有F. proliferatum分离株中，pr23和pr26这两个分离株分别具有最高和最低的毒力。玉米自交系对真菌和一种真菌的不同分离物的敏感性不同。获得的结果指出，F。proliferatum是玉米的重要致病物种，可引起严重的坏死甚至幼苗衰变。
