A Rapid and Non-Destructive Technique for Measuring the Area of Cucumber Leaves.

Cucurbit Genetics Cooperative Report 9:33-36 (article 9) 1986 D.L. Visser Institute for Horticultural Plant Breeding (IVT), P.O. Box 16, 6700 AA Wageningen, The Netherlands Leaf area measurements are an essential part of growth analyses. For most measurements, plants need to be defoliated so that leaf area can be measured with a photo-electrical area meter. Growth […]

Malate Dehydrogenase Variation in African Cucumis species: A Testable Genetic Hypothesis

Cucurbit Genetics Cooperative Report 9:18-23 (article 6) 1986 J.E. Staub USDA, ARS, Department of Horticulture, University of Wisconsin, Madison, WI 53706 Electrophoretic, cucurbitacin and flavonoid variation; chromosome homology; and plant morphology have been studied to determine taxonomic relationships among cross-compatible species of Cucumis (1, 2, 4, 7, 8, 10, 11, 12, 15). These studies have […]

Leaf Area Prediction Model For Field Grown Cucumbers

Cucurbit Genetics Cooperative Report 9:15-17 (article 5) 1986 N.S. Robbins and D.M. Pharr Department of Horticultural Science, North Carolina State University, Raleigh, N.C. 27695-7609 Several recent studies have suggested that fruit yield in cucumber might be limited by photoassimilate supply (1, 2). Changes in potential for photoassimilate production are related to photosynthetic rate per unit […]
