摘要
概述了环线虫对农林植物的为害情况。在环线虫引起的植物病害中 ,小环线虫可引起梨树早衰病 ;半穿刺线虫可引起柑橘慢衰病 ;针线虫、鞘线虫和半轮线虫都可以引起植物的衰退病。简要介绍了此类线虫的防治方法。
WT5BZ]Criconematina is an important plant parasitic nematode.Some kinds of them may injure crops and trees. Criconemelle causes pear tree short life. Tylenchulus is the cause of “slow decline” of citrus. Paratylenchus,Hemicycliophora and Hemicriconemoides may damage wide variety of host plants. Some methods to control them are introduced simply. [WT5HZ]Key words:[WT5BZ]criconematina;plant disease;controlcharacters in creal crops. The results indicated that protein content and absolute contents of four protein fraction were greatly controlled by maternal genetic effects and endosperm genetic effects, little by cytoplasmic effects. Direct and maternal heritability of the five characters were significant, so selection was effective in the early generation.
