1. Flower primordia were present on plants of Taraxacum kok-saghyz collected from several localities in the central or northern parts of the United States during the late fall or winter months. Photoperiods of 8, 10, 12, 14, 16, and 18 hours did not inhibit the development of these primordia into mature flowers when the plants were transplanted in the greenhouses. 2. Wide variability of leaf pattern was observed in the seedlings, but morphological characteristics of the flowers indicated that… Expand
Temporal diversity of Taraxacum kok-saghyz plants reveals high rubber yield phenotypes
Across all growing conditions and developmental stage, the highest rubber yields per plant were found in plants with large roots combined with a large rosette, and an above average rubber concentration, and rubber concentration was heritable. Expand
Harvest date, post-harvest vernalization and regrowth temperature affect flower bud induction in Russian dandelion (Taraxacum kok-saghyz)
Russian dandelion (Taraxacum kok-sagyz Rodin; TKS) is a promising candidate for introducing natural rubber production into North America; however, a comprehensive analysis of factors that influence flowering is essential for efficient breeding and crop development. Expand
Breeding for Improved Germination Under Water Stress, and Genetic Analyses of Flowering Habit and Male Sterility in Russian Dandelion (Taraxacum kok-saghyz)
It is demonstrated that Russian dandelion has potential to be adapted as a crop for rubber production in North America and can be restored to fertility by a nuclear restorer of fertility gene. Expand
The physiology and biochemistry of rubber formation in plants
It is the purpose of this review to survey the present knowledge concerning the production of rubber by plants, especially the factors, environmental and internal, which influence rubber production,Expand
A review of literature onTaraxacum koksaghyz Rod
A survey of the Russian literature on rubber-bearing plants in general and on kok-saghyz is carried out, restricted to those papers that are to be found in certain American and Canadian Libraries and hence are most readily available to the North American investigator. Expand
