Sterols of Mulberry Leaves and Small Leaf Curl Disease
      
Free and bound sterols of leaves of five mulberry cultivars differing in their susceptibility to small leaf curl disease have been studied.
      
Three factors contributing to the increase of cocoon output are: the cocoon output per box, the area of mulberry field, and the egg amount raised per unit area of mulberry field.
      
The results showed that the importance of the factors in increasing cocoon output was in the order: egg amount raised per unit area of mulberry field >amp;gt; cocoon output per box >amp;gt; area of mulberry field.

The symptoms of mulberry dwarf in Kwangtung are similar to those reported from EastChina.The rate of the disease incidence in most places is generally below 10%,but in somelocalities may be as high as 50-80%.The yield of leaves of infected plants in weight wasestimated to be about 30% of that of healthy plants.The shape and size of the cocoons pro-duced by the silkworms feeding on infected leaves are not uniform,and the luster is inferior.The results of transmission tests by grafting show:(1) that the disease...

The symptoms of mulberry dwarf in Kwangtung are similar to those reported from EastChina.The rate of the disease incidence in most places is generally below 10%,but in somelocalities may be as high as 50-80%.The yield of leaves of infected plants in weight wasestimated to be about 30% of that of healthy plants.The shape and size of the cocoons pro-duced by the silkworms feeding on infected leaves are not uniform,and the luster is inferior.The results of transmission tests by grafting show:(1) that the disease is graft-trans-missible,confirming the virus nature of the disease and further suggesting its identity withthe mulberry dwarf in East China;(2) that not all the buds (including the portions of woodto which the buds were attached) of the infected twigs are infected with the virus in Springand even in Summer;(3) that the virus is present in only some of the roots and even only ina portion of a root,and that the small lateral roots (smaller than 2.2 mm in diameter) areall completely free from the virus.Two kinds of leaf-hoppers (one of which is Erythroneura mori Matsumura) and mulberrywhite-fly (Bemisia myricae Kuwama) so far tested fail to transmit the disease.All of the 2684 seedlings grown from seeds Collected from infected mulberry treesappeared to be healthy up to six months old.It is thus unlikely that the disease is seed trans-missible.

广东桑树萎缩病的症状与江浙黄化型桑树萎缩病基本相同。主要发病地区为顺德、南海、中山、新会和鹤山等县,发病率一般在10%以下,严重的达50—80%。病株减产达70%,用病叶饲蚕所生产的丝茧缺乏光泽,茧形不整。各种嫁接传病试验结果说明:(1)本病可借嫁接传染,进一步说明本病和江浙黄化型桑树萎缩病可能完全相同;(2)发病初期及中期的枝条,不是每一个芽都含有病毒;(3)病树的根,只部分含有病毒。用桑树上常见的两种浮尘子(其中一种为 Erythroneura mori Matsumura)及一种粉虱(Bemisia myricae Kuwama)分别进行传病试验,未获成功。种籽传病试验结果:病株种籽所长出的2684株桑苗全部没有发病,初步说明种籽传病的可能性不大。

The present list includes 82 species of fruit crop diseases on 14 species of fruit crops.16 species of tea,camellia and mulberry diseases,30 species of tree plant diseases on 12 species of tree plant,which were collected by the author during 1951-1960 in Fuzhou suburbs.Parts of these diseases are new recorded to Fujian province up to date

本文为1959~1960年在福州附近14种果树上发生的病害82种、茶和油茶病害13种、桑树病害3种及12种树木上发生的30种病害名录。其中在我省至今仍是新记载的病害在中文病害名称前有“△”作标记。

In the spring of 1980,a new bacterial disease of mulberry tree was found in Jiangsu Province. The dorment buds of the shoot were killed by the causal organisum and could not grow to form new shoots in the next spring.The causal organisum is identified as Pseudomonas syringae but is different from P.syringae pv.mori in pathogenicity and bacterial characteristics. Whether this is a new pathovar of P,syringae is still under investigation.

根据病害的发生时期、症状和病原菌的生理生化的特性、血清学反应、致病性等方面的比较研究的结果,证明桑细菌性枝枯病的病原细菌也是一种丁香假单孢杆菌(Pseudomonas syringae Van Hall),但它不同于桑细菌性疫病的病原细菌[另一个丁香假单孢杆菌(Pseudomonas syringae pv.mori)]。所以我们认为桑细菌性枝枯病是桑树的一种新病害。
