Phaseolus vulgaris, the common bean, is susceptible to many
bacterial, fungal and viral diseases. However, resistance to several
diseases has been identified in related Phaseolus species, P.
coccineus, P. acutifolius and P. lunatus. Thus, interspecific
hybridization could result in transfer of beneficial characteristics.
One of the problems encountered in interspecific...
A critical balance of hormones is necessary for normal plant
development. Therefore, precise mechanisms must exist to maintain
proper levels of cytokinins, a group of hormones regulating cell
division and differentiation. Structural modifications of the naturally
occurring cytokinin, zeatin; including the oxidation, O-glycosylation
and reduction of the N⁶-side chain; may...
In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...
Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the
most troublesome perennial weeds of agricultural lands in tropical and some
temperate regions. This research sought to determine the effects of timing of
herbicides, shading, and soil moisture on plant population growth and tuber
production of purple nutsedge...
Most of the presently grown cultivars of rice (Oryza sativa L.) have poor
competitive ability against weeds if compared with traditional cultivars. Therefore,
effective weed control is an important but often costly and difficult management
practice in rice crop production. If weed competitive ability of rice cultivars could be
improved...
