Trypsin method was used in combination with sevage method while getting rid of the protein, corn smut fungus'thick polysaccharide purification effect was better than the method of sevage method.
Identification of disease and pest resistance was done by Institute of Plant Protection, Hebei Academy of Agricultural Science, and the variety demonstrated resistance to southern blight leaf; mid-resistance to stalk rot, corn Curvularia leaf spot; high resistance to northern blight leaf, corn smut, corn dwarf mosaic; and sensitive to corn borer.

The 30 billions ball shaped nanodiamond prticles not only reduce the friction of metal surfaces, furthermore it will transform the sliding friction into rolling friction, and is the most excellent anti friction metal conditioner and lubricating additive ever.
In other smuts the spores form an uncovered mass of black powder.
Other diseases might be caused by fungus which attacks the plant in the form of a mold or smut or rust.
In the recent years, we extended widely the new methods controlling rice kernel smut disease, of which Kanghei 95 was as the center. As a result, significant social and economic benefits were achieved.
By contrast withthe traditional using methods, the new formulation can reduce the labor intensityeffectively, and enhance the labor productivity greatly, with better controlling effect.
Rice kernel smut is a kind of common disease on hybrid rice which is causedby Neovossia horrida fungus.
Because its damage on rice was not serious inconventional rice, its controlling methods and fungicides about the disease haveseldom been studied.
It was found that the disease seeds and sclerotia, mainly kernel smut and false smut seeds, could account for 3.65% of the total seeds and each gram seeds burthen 1.65×10^5 spores.
Category used in some systems to comprise the two orders Ustilaginales and Uredinales.
More than 20 taxa of airborne fungi have been collected, among which the most common fungi were Uredinales, Ustilaginales, Alternaria, etc. Fungi spores were ralated with the season and weather, the most aboudant period in sring and summer.
14. 结果 经1年的调查，曝片观察到的35 746个真菌孢子和曝皿观察到的1 188个菌落，分属于4个亚门60个种属，常见菌种有黑粉菌、交链孢菌、锈菌、枝孢芽枝菌、芽枝菌、皮思菌、大孢枝孢菌、黑曲菌、杂曲菌和烟曲菌。85例婴幼儿哮喘患儿，39例真菌变应原皮内试验阳性（45.9％），260例儿童哮喘患儿，108例皮试阳性（41.5％），总阳性率42.6％。
Results Observation of 35746 grain of airborne fungi spores and 1188 grain of fungi spores for one year revealed the following species of fungi: Ustilaginales, Aternaria, Uredinales, Clodoporium cladosporioides, Cladosporium, Pithomyces, Cladosporium macrocarpum, Aspergillus niger, Aspergillus versicolor and Aspergillus fumigatus. Thirth-nine of 85 infants and young children with asthma (45.9%) showed positive skin test and 108 of 260 older children with asthma (41.5%) were positive for the skin tests; total positive rate was 42.61%.
objective in order to investigate the variety of the airborne fungi in jingzhou area and study the relationships between airborne fungi and allergic diseases. methods we surveyed the fungi sensitizing of air in jingzhou city from feb.1th, 2007 to jau.31th, 2008 to quantitatively observe the daily airborne fungi and count under microscope through one year. results the fungi spores were present through all year. more than 20 taxa of airborne fungi have been collected, among which the most common fungi were uredinales, ustilaginales, alternaria, etc. fungi spores were ralated with the season and weather, the most aboudant period in sring and summer. conclusion the airborne fungi were seen one year and were mostly allergenic. many of then had seasonal distribution.
Cheap nonconductive oxide is used as a black powder of a black layer.
Since coffee became my addiction, I need the black powder everyday.
18. 茭白(Zizania caduciflora Turcz Hand-Mazz)，为禾本科多年生水生宿根性草本植物，是受一种食用黑粉菌Ustilago esculenta P。
Zizania caduciflora is perennially hydrophytic herb that is a member of the Gramineae family, which is a swelling stalk after parasitized by Ustilago esculenta.
19. 根据引起病害的症状特点，参照相关文献将其鉴定为山药条黑粉菌(Urocystis dioscoreae Syd。·)。
According to morphology of the telispore and telispore balls, the pathogen was identified as Urocystis dioscoreae Syd.
The water extractive water soluble polysaccharide B 1 and the alkali extractive water soluble polysaccharide B 2 were extracted from ustilaginaceae.
