花生花叶病是我国花生产区近几年来发生的一种比较普遍的病害。余大绂(1939)首先报导了山东的太安、兖州发生该病,周家炽等(1959)报导北京郊区亦曾发生。1975年以来该病害大流行于全国,尤以山东、江苏、辽宁等省花生产区发生较重,近年在北京、河北、河南、安徽等省亦有不同程度的发生为害。花生花叶病的症状:叶片上产生许多不定型的绿色及褪绿部分相嵌而显现出黄绿相间的斑纹,称为花叶。受害轻者,虽对生长发育影响不大,但长势变弱,结果数量减少;受害严重者,整株变矮,叶片变为兔耳状皱缩,而且变厚而色深,结果数明显减少或果形变小,甚至不结果,有时个别的果皮曝裂并露出紫红色的籽仁。
Peanut mosaic disease is a common disease occurred in the flower production area of our country in recent years. Yu Dao (1939) first reported on Tai’an in Shandong Province and Yanzhou on the disease. Zhou Jiachi et al. (1959) reported that Beijing’s suburbs have also occurred. Since 1975, the disease pandemic has occurred in the whole country especially in the flower production areas of Shandong, Jiangsu and Liaoning provinces. In recent years, the epidemic has also taken place in varying degrees in Beijing, Hebei, Henan and Anhui provinces. Peanut Mosaic Symptoms: Many unfixed green and chlorotic parts of the leaves are embedded and appear yellowish green and white stripes, called mosaic. The less affected persons have little effect on the growth and development, but their growth is weakened and the number of the results is reduced. In the severely affected persons, the whole plant becomes shorter and the leaves become rabbit ear-like shrinkage, and the thickening and darkening of color lead to a significant decrease in the number of results Or the fruit becomes smaller, not even fruit, sometimes individual peel and expose the exposed reddish seed kernels.
