The water permeability of tissues was investigated by measuring the efflux of (3)HHO from previously loaded (in darkness) etiolated bean buds (Phaseolus vulgaris L. var. Red Kidney), pea epicotyl segments (Pisum sativum L. var. Alaska), and oat coleoptile segments (Avena sativa L. var. Garry). Red light, far red light, or darkness was applied at the time of transfer of tissue from labeled to un...

Alkaline phytase activity, with a pH optimum of 8, was recovered from detergent extracts of dormant seeds of nine varieties of Phaseolus vulgaris L., Pisum sativum L. var. Early Alaska, and Medicago sativa L. This alkaline phytase of legume seeds was activated by calcium and differed from most seed phytases in its relative insensitivity to inhibition by fluoride.

The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), highly prefers to oviposit on yellow rocket, Barbarea vulgaris (R. Br.) (Cruciferae) var. arcuata , despite larvae not being able to survive on it, suggesting it may have potential as a trap crop. In a no-choice greenhouse experiment, P. xylostella laid 28% more eggs on B. vulgaris than on cabbage. Within the B. vulgaris...

I. Nomenclature: A) Cannabis sativa L.; B) marihuana, hemp, Mary Jane; chanvre (Fr.); canamo (Sp.); konopli (Ru); Kanf (Gr.) (Fig. 1); C) synonyms: There are many names for the horticultural variants of Cannabis sativa. Some names have been validly published in accordance with the International Code of Botanical Nomenclature. Names used in the literature (valid and invalid) include: C. ruderali...

As significant differences in cellular physiology, metabolic potential and genetics occur among strains with morphological similarity, the screening of appropriate microalgae species for effective CO2 fixation and biodiesel production is extremely critical. In this study, ten strains of Chlorella were cultivated in municipal wastewater influent (MWI) and their tolerance for MWI, CO2 fixation ef...

Peanut diseases, such as leaf spot and spotted wilt caused by Tomato Spotted Wilt Virus, can significantly reduce yield and quality. Application of marker assisted plant breeding requires the development and validation of different types of DNA molecular markers. Nearly 10,000 SSR-based molecular markers have been identified by various research groups around the world, but less than 14.5% showe...

GOLD, R. E., and K. MENDGEN. 1984. Vegetative development of Uromyces appendiculatus var. appendiculatus in Phaseolus vulgaris. Can. J. Bot. 62: 2003-2010. The morphology of intercellular and intracellular hyphae derived from basidiospores of Uromyces appendiculatus var. appendiculatus is described. Light and electron microscopic observations of the bean tust fungus were made on susceptible lea...
