The spikes of Su-Mai No.3, Xin-Zhong-Chang, Dong-Hai No. 63 and Nong-Ling No.61 were inoculated with spore suspension at flowering stage. The spikes samples at 20, 44 and 96~98 h after inoculation wereimmediatly fixed in F. A. A. Then wax-slices were made and observed with a microscope. The observation results indicated that the fungus of wheat scab penetrated directly external epidermis of anther and internal epidermis of flume.

The spikes of Su-Mai No.3, Xin-Zhong-Chang, Dong-Hai No. 63 and Nong-Ling No.61 were inoculated with spore suspension at flowering stage. The spikes samples at 20, 44 and 96~98 h after inoculation wereimmediatly fixed in F. A. A. Then wax-slices were made and observed with a microscope. The observation results indicated that the fungus of wheat scab penetrated directly external epidermis of anther and internal epidermis of flume. Also the fungus invaded into anther tissues cracked naturally. Observation of 36 spikelets showed in most cases (31 of 36 samples) the anther was infected at first, and then spread to epidermis of flume (horizotal spread) and ovary (vartical spread)which was mainly infection process. Usually, vartical spread was quicker than horizotal one, because the glume inhibit the horizotal development of fungus. Thus, spikelets which were partially infected and partially uninfected were found.

对苏麦三号、新中长、东海63和农林61等4个品种36个接种小穗的石蜡切片,进行显微镜观察。结果指出,小麦赤霉病菌可以菌丝直接侵入颖片或花药表皮,也可以通过花药的自然裂口侵入。最先侵染的部位是花药,其次为颖片内侧壁及小穗基部缝隙内的组织。观察表明,病菌首先侵染花药,然后横向扩展侵染靠近花药的颖片内侧壁,及垂直向下蔓延至子房的侵染方式占31个,是典型的侵染过程。研究结果还指出,病害在小穗内的发展,由于颖片对病茵扩展的阻隔作用,垂直扩展快于横向扩展,造成小穗的半病半健状况。

Using tobacco anther culture and toxin selection, a selecting system of tobacco black shank disease resistant mutant has been set up. The system consists the fallowing steps: (1). Anthers of susceptible varieties are mutagenized with γ-ray 500-2000 rods. (2) Screening toxin tolerant pollen plants in anther culture medium containing 50-80% crude toxin. (3) Disease resistance of the toxin tolerant pollen plants is tested with in vitro leaf-assay method. (4) The resistance of the offsprings of disease...

Using tobacco anther culture and toxin selection, a selecting system of tobacco black shank disease resistant mutant has been set up. The system consists the fallowing steps: (1). Anthers of susceptible varieties are mutagenized with γ-ray 500-2000 rods. (2) Screening toxin tolerant pollen plants in anther culture medium containing 50-80% crude toxin. (3) Disease resistance of the toxin tolerant pollen plants is tested with in vitro leaf-assay method. (4) The resistance of the offsprings of disease resistant plants is retested, and the plants of which resistance can be transmitted through sexual reproduction are considered to be disease resistant mutants. Both the treatment of y-ray and high toxin concentration can give disease resistant pollen plants. About 9-50% of the pollen plants produced by either of the two treatments have shown disease resistance. Some of these plants can produce resistant offsprings white some can not. Using this system, we have got 6 resistant mutants from 2 highly susceptible varieties and 4 resistant lines from 2 F1 hybrids of Res. Var. X Suscept. Var. with stable resistance within 3-4 generations. Resistance of the mutant R-400, selected from a susceptible variety "Small Golden 1025", seems to be controlled by multiple genes with an incomplete dominance.

经实验我们成功地建立了在细胞水平上筛选烟草抗黑胫病突变体的筛选体系。该体系的主要内容为:γ-射线500—2000拉德诱变高度感病品种的花药后用50—80%的黑胫病菌粗毒素为选择压力,筛选出抗毒素花粉植株,用离体叶片法测定选出抗病植株,再从后代鉴定中选出抗病性能够稳定遗传的突变系。γ-射线及高浓度毒素处理均能得到抗病植株。选自感病品种的花粉植株中约有9—50%是真正抗病的。这些抗病植株中有一部分的抗病性能够稳定遗传。用该法已从感病优质品种小黄金1025及乔庄黑苗中选出6个突变系。并自N.C.628(抗)×小黄金1025(感)及N.C.628(抗)×庆胜2号(感)的F_1花粉植株中选出4个抗病系。所有的抗病系经3—4代后均表现出稳定抗性。其中一个突变体(R400)的抗性似由不完全显性多基因控制。

This paper determines the kinds of viruses and their distributions in the main strawberry producing regions of China by means of indicator leaf grafting and proposes the methods for identification and detection of the viruses. We have obtained the virus -free mother plants of 12 strawberry cultivars with anther culture and established the mode of production of virus-free strawberries, which is suitable to Chinese conditions. Virus-free strawberries produced by runner propagation in isolated fields from strawberry growing areas have been cultivated in 17 provinces or cities of China and increased 7.8-45.1% in yield, compared with virus-infected strawberries.
