Zinc Nutrition Of Rice Plants As Influenced By Seed Germinated In Zinc Solutions, Narsimaha R. Kasireddy, Lyell F. Thompson
Zinc Nutrition Of Rice Plants As Influenced By Seed Germinated In Zinc Solutions, Narsimaha R. Kasireddy, Lyell F. Thompson
Journal of the Arkansas Academy of Science
In recent years a physiological disorder of rice (Oryza sativa L.) seedlings growing in soils high in exchangeable calcium has been diagnosed as zinc deficiency. Calculations show that less than 30 g of zinc is needed to satisfy the nutrition of a hectare of 6-8-wk-old rice plants. Rice seed was soaked and germinated in dilute solutions of zinc ethylenediamine tetraacetate, zinc sulfate and zinc lignosulfonate prior to planting in greenhouse pots containing a zinc-deficient soil. The rice plants grown from the zinc-treated seed produced more growth and sorbed more zinc than rice plants grown from untreated seed.
Seed Germination In Ginkgo Biloba L. I. Influences Of Cold Treatment, Gibberellic Acid And Red Light, Michael I. Johnson, James L. Wickliff
Seed Germination In Ginkgo Biloba L. I. Influences Of Cold Treatment, Gibberellic Acid And Red Light, Michael I. Johnson, James L. Wickliff
Journal of the Arkansas Academy of Science
The influences of cold treatment, gibberellic acid and red light treatment on rate of germination of seeds of Ginkgo biloba L. were followed for a 12-wk period. Dispersal units were collected, and the outer fleshy layer was removed soon after harvest. Of water-imbibed, non-cold-treated seeds, 50% of those which germinated did so within 11 wk after planting. A single application of red light accelerated the 50% germination time by 3 wk. Imbibition in GA3 solution did not appear to accelerate germination. With 4-wk cold treatment the 50% germination time was accelerated 6 wk in water-imbibed seeds. Both red light and …
