摘要
在四个菜豆品种“沙克沙”、“家雀蛋”、“自来油”、“白大架”上按种菜豆花叶病毒(Bean Common Mosaic Virus(BCMV)V-5],接种后15—25天测定,病毒在植株体内的浓度达到高峰。同时,植高、叶面积,叶绿素总量,光合速率较健康株明显下降,呼吸强度、游离态氨基酸总量上升。接种后30—35天,病毒含量开始下降,光合速率,呼吸强度、株高几乎接近正常水平。叶面积、叶绿素总量,游离态氨基酸总量同健株的差异也大大减少。继病毒侵入后植株生理代谢的失调,温室盆栽条件下,菜豆不同品种的产量损失为40—64％。
Inoculating the Bean common mosie virus (V-5) on four bean cultivars—'Shakesha' 'Jiaqiaodan' 'Zilaiyou' and 'Baidajia', then investigating the plants 15 days later, concentration of virus in bean plants reached top level. Meanwhile, the hight of plant, leaf size, the whole mount of chlorophyll and the photosynthetic rate decrease obviously,on the contrary, respiration and free amino acid increase as compared with the healthy plants.From thirty to thirtyfiev days after inoculating, the amount of virus in plants is getting down, photosynthetic rate, respiration and the hight of plant almost revive to the normal level. The difference between the infected and healthy plant of leaf size and chlorophyll reduces greatly. Following a series of imbalance with physiological metabolism, the list of yield among four cultivars on the condition of greenhouse is 40—64% separately.
