Cucumber Reports
Hisopathology of Cucumber Resistance to Downy Mildew
Cucurbit Genetics Cooperative Report 18:26-28 (article 12) 1995 Qing Ma, Hongwen Cui Department of Plant Protection, Northwestern Agricultural University, Yangling, Shaanxi 712100, P. R. China; Department of Horticulture, Northwestern Agricultural University, Yangling, Shaanxi 712100, P.R. China Downy mildew, Pseudoperonospora cubensis (Berk. et Curt.) Rastow, is the most destructive cucumber disease in China. Breeding for disease […]
Heredity Analysis of Photosynthetic Rate and Chilling Tolerance of Cucumber Seedlings Under Low Temperature
Cucurbit Genetics Cooperative Report 18:23-25 (article 11) 1995 Janguo Li, Hongwen Cui and Meng Zhang Horticulture Department, Northwestern Agricultural University, Yangling, Shaanxi, 712100, P.R. China Increased attention is now being given to cold resistance in cucumber (Cucumis sativus L.). Cold resistance in cucumber includes two aspects: low temperature tolerance (10-15C) and chilling tolerance (0-5C). Although […]
Chilling Sensitivity in Cucumber Seedlings: Ethylene Production
Cucurbit Genetics Cooperative Report 18:21-22 (article 10) 1995 Jianhui Liu and Hongwen Cui Department of Horticulture, Northwestern Agricultural University, Yangling, Shaanxi 712100, P.R. China Chilling injury can occur during cucumber production (2). The most feasible method of increasing the chilling resistance of crop plants is by genetic manipulation. Breeding for chilling resistance requires a method […]
Alteration of Catalase Activity and Ethylene Release during Germination in Newly-Harvested Cucumber Seeds
Cucurbit Genetics Cooperative Report 18:19-29 (article 9) 1995 Mingan Yin and Hongwen Cui Dept. of Horticulture, Northwestern Agricultural University Yangling, Shaanxi 712100, P.R. China In cucumber (Cucumis sativus L.) breeding and seed production, we often want to utilize newly harvested seeds for multiplication. However, the vigor of these seeds is low and their regrowth is […]
Effect of Hot Treatment on the Vigor of Newly-Harvested Cucumber Seeds
Cucurbit Genetics Cooperative Report 18:17-18 (article 8) 1995 Hongwen Cui and Mingan Yin Dept. of Horticulture, Northwestern Agricultural University, Yangling, Shannxi 712100, P.R. China Newly-harvested cucumber (Cucumis sativus L.) seeds pass through a physiological process called “after-ripening” before they are sown in China (2). Newly-harvested seed have low vigor and seedling establishment is often difficult. […]
The Relationship Between Storage Time and Viability of Cucumber Seeds (Cucumis sativus L.)
Cucurbit Genetics Cooperative Report 18:16 (article 7) 1995 Huanwen Meng, Zhihui Cheng, Hongwen Cui and Engrang Zhang Department of Horticulture, Northwestern Agricultural University, Yang Ling, Saanxi 712100, P.R. China Introduction. Although it is well known that plant seeds will lose their vigor and viability during storage, there is a saying in China that the potential […]
Cucumber (Cucumis sativus L.) Induced Mutations: A Female Sterile Mutant and An Independent Long Hypocotyl Mutant
Cucurbit Genetics Cooperative Report 18:13-15 (article 6) 1995 K. Niemirowicz-Szczytt, M. Rucinska, A. Korzeniewska and S. Malepszy Department of Genetics and Hort. Plant Breeding, Warsaw Agricultural University, SGGW, 02-766 Warsaw, Poland As with previously described mutants (2-5), the two mutants reported here belong to our collection developed by Kubicki. Mutants were obtained by ethyleneimine seed […]
Principal Component Analysis for Traits Selection in Cucumber Breeding
Cucurbit Genetics Cooperative Report 18:10-12 (article 5) 1995 Hongwen Cui, Meng Zhang, and Huanwen Meng; Junjun Deng Department of Horticulture, Northwestern Agricultural University, Yangling, Shaanxi, 712100, P.R. China; Xi’an Vegetable Research Institute, Shaanzi, 71200, P.R. China It is not easy to select for numerous traits during crop improvement (3). Principal component analysis (PCA) is a […]
Problems Associated with the Selection of Determinate Cucumber (Cucumis sativus L.) Plant Types in a Multiple Lateral Background
Cucurbit Genetics Cooperative Report 18:7-9 (article 4) 1995 J.E. Staub, Jeff Bacher and Linda Crubaugh Vegetable Crops Research, USDA/ARS, Departments of Horticulture, University of Wisconsin-Madison, WI 53706 USA Introduction. To respond to the need for cultivars suitable for mechanical harvesting our breeding project is manipulating cucumber plant architecture to develop high yielding genotypes. Standard cucumber […]
