Changes in Nitrogen and Protein Content of Cowpea (Vigna unguiculata) due to Geminivirus Infection
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
Cowpea, Vigna unguiculata is an important legume crop cultivated worldwide as vegetable and pulse crop Cowpea is susceptible to many virus diseases amongst which geminivirus infection is more prevalent in northern India. Yellow mosaic caused by geminivirus for which whitefly acts as a vector reduces yield from 40-80% area. Virus infection generally results in the drastic bio-chemical and physiological changes in the host plants. For the estimation of protein and nitrogen, stem and leaf samples were collected separately from healthy and infected cowpea plants at various intervals. In the present study it was observed that the infection had increased the total nitrogen and protein content of the host plant. The higher nitrogen content in the infected plant nitrogen content was found to be maximum in leaves. infected leaves and stem had higher protein and nitrogen contents than their healthy counterparts although protein and nitrogen contents of the plants also increased with time.
