| 摘要: |
| 检查陕西中部的小麦种子样品,发现种表附着真菌孢子40种,大致属于19个真属。分离14个县(市)30份样品的1500粒种子,得到种内寄藏真菌500多株。除20％左右在供试条件下未产孢外,其余分属于18属33个种。其中链格孢菌出现机率最高,仅细链格孢即占23.7％,其次为离蠕孢菌,仅麦根腐离蠕孢即占13.1％。文中对少见种,特别是10个国内新纪录种,作了简要描述和图示。 |

| Abstract: |
| 40 kinds of fungal spore types as parts of 19 genera were found from the surface of 800wheat grains of 8 samples.Over 500 colonies of fungi Were obtained from inside of 1500 wheat grains of 30 samples (26 cultivars) , in which were collected from 14 counties (municipalities) in the middle part of Shaanxi Province, by culturing the surface sterilized grains on PDA plates. The spore producing ones were identified belonging to 33 species of 18 genera. Besides, there are about 20% of the colonies remaining sterile. Among the identified fungiAiternarta spp. rank the first proportion, e.,g. A. tenuts alone makes up of 23.7%of the spore producing colonies; Bipclaris spp. take the second, e.g. B.sorokintana alone accounts for 13.1% of the colonies. Also, the paper briefly described and illustrated some rare species, particularly with 10 new Chinese records. |
