Cowpeas

Date: 1908
Creator: Nielsen, H. T. (Harold T.)
Description: "The cowpea is the most valuable legume for the Southern States and its use would be much more extensive were it not for the relatively high price of the seed, most of which is still picked by hand. Particular attention is therefore given to the matter of harvesting seed by machinery now in very successful use in several communities. These methods are so far perfected that the cowpea seed crop should receive much greater attention in favorable localities." -- p. 5. This bulletin also discusses the use of cowpeas for hay, seed mixtures of cowpeas and other crops, the nutritional value of cowpeas in animal feeds, growing practices, and the several different varieties of cowpea.

Callus Development and Organogenesis in Cultured Explants of Cowpea (Vigna unguiculata (L.) Walp

Callus Development and Organogenesis in Cultured Explants of Cowpea (Vigna unguiculata (L.) Walp

Date: December 2004
Creator: Omwenga, George Isanda
Description: Cowpea, Vigna unguiculata (L.) Walp is an excellent source of protein, vitamins and minerals and a major food crop many parts of Africa. Optimal production levels are hampered by insect pests and diseases. Biotechnological techniques such as tissue culture and genetic engineering can aid in the development of varieties with resistance to insect pests and diseases. The objective of this study was to investigate conditions necessary for the development of a reproducible tissue culture system that can be applied to regenerate transformed cells from culture. The in vitro manipulation of cowpea using Murashige and Skoog (MS) medium, auxins and cytokinins resulted in the formation of callus and rhizogenesis. Calli that were formed were separated into six classes based on color and texture. Yellowish friable callus, yellowish compact, soft yellowish callus and green and white were composed of largely vacuolated cells and were non-regenerative. Friable green callus was the most prevalent callus type and could form of roots in some hormone combinations. Green spots were formed on hard compact green callus. The green spots became nodular, forming root primordia and ultimately giving rise to roots. None of the six calli types gave rise to the formation of shoots. Embryogenic callus was ...
