Orange leaf disease of rice was first observed in northernThailand in 1960. Since then it has been reported successively inphilippines (1963),India (1967),Malaysia (1969) and Sri Lanka (1970).But there is no report in China. In the fields,the naturally diseased plants showed golden yellowto orange leaves.Later, these discolored leaves gradually rolledinward and dried out beginning from the tip. On inoculated plantsthe defined orange stripes running along the veins appeared on theouter margin or on only one side of the leaf blade near the tip.Later, the colour of leaves rapidly turned from golden yellow toorange and rolled inward. The diseased plants produced fewertillers and poor roots. Death of the plants resulted when infected inearly stages. The disease was transmitted by the zigzag leafhopper (R.dorsalis),but not by Nephotettix cincticeps; N.virescens and N.nigropictus. Therelation period in the insect was 14-18 days at 24.6-25.1℃ andthe incubation period in the inoculated plant was 13 days at 17°±1℃The virus is persistent in the vector.

水稻橙叶病过去在我国没有发生的报道,1978年在云南省西双版纳州景洪等地的稻田中,第一次发现有水稻橙叶病病株。1979年作者对其病状、介体昆虫种类和传毒特性进行了初步观察研究,所获结果与国外有关报道基本一致。

Since the discovery of rice orange leaf disease in Yunnan province. China.1978.some other provinces such as Fujian.Guangdong and Guangxi also have found the same disease recently.Investigations showed that the disease could only be transmitted through the Zig-zag rice leafhopper (Recilia dorsalis),while two other species of rice leafhoppers (Nephotettix cincticeps,N virescens)and three species of planthoppers (Nilaparvata lugens.N bakeri and N muirichina)did not transmit it Besides,it was noncontagious...

Since the discovery of rice orange leaf disease in Yunnan province. China.1978.some other provinces such as Fujian.Guangdong and Guangxi also have found the same disease recently.Investigations showed that the disease could only be transmitted through the Zig-zag rice leafhopper (Recilia dorsalis),while two other species of rice leafhoppers (Nephotettix cincticeps,N virescens)and three species of planthoppers (Nilaparvata lugens.N bakeri and N muirichina)did not transmit it Besides,it was noncontagious from the soil,or even through mechanical means by the sap of diseased plants.The virus incubates and spreads by the insect vector. Recilia dorsalis Electron microscopic examinations of ultrathin sections of the diseased plant tissue revealed that the virus-like particles appeared spherical in shape and measured 15 nm in diameter.Being not sensitive to the treatment with tetracycline antibiotics,we thus concluded that the pathogen in China is not a MLO,but most likely a virus.

水稻橙叶病自1978年在我国云南发现以来,近年在福建,广东和广西的一些地区亦有发生。研究表明,病害只能由电光叶蝉(Recilia dorsalis)传播;两种黑尾叶蝉和三种飞虱不能传播,汁液摩擦和带病土壤也不传病。病毒在电光叶蝉体内属增殖型。病株超薄切片在电镜下见到类似病毒的球状颗粒,直径约15nm,病害对四环素不敏感,因此认为我国水稻橙叶病的病原似应是病毒,而非类菌原体。

Oranges suffering from Zn-deficiency often result in chlo rosis in the intei'-veinal ateas of the leaf, and it can be eliminated by sprinkling zinc fertilizer After studying with an electronic microscope the ultrastructures of the orange leaves Iccking zinc and those sprinkled with zinc fertilizer, we discover. (1) The major characteristics of leaf calls of Zn-deficient plants are that the cytoplasm, the endoplasmic reticulum and the ribosomes are poor, and that there are generally big starch grains in the chloroplasts. (2) After the sprinkling of zinc fertilizer, the structure of leaf cells returns to normal; the [cytoplasm is rich, the amount of chloroplast increases, and a lot of rough endoplasmic rgticulum with various shapes in the cytoplasm can be found. Furthermore, the complented Zinc can promote the photosynthesis of Zn-def icient plants and improve their N-metabolism, so that the yield of the fruit can be increased and the quality improved

柑桔缺锌导致发生叶脉间缺绿症,喷施锌肥后此种症状即可消除。使用电镜研究了缺锌柑桔树叶片及喷施锌肥消除缺绿症后的叶片超微结构,发现缺锌叶细胞的主要特征是细胞质基质、内质网及核糖体稀少及叶绿体中包含有大的淀粉粒。喷施锌肥后可使细胞结构恢复正常,细胞质浓厚,叶绿体数量增加,并出现大量多种形态的粗面内质网,从而可改善氮素代谢,促进光合作用,增加产量,改良品质。
