ELECTRICAL CONDUCTIVITY AS AM~A~URE OF PLANTING SE~D QUALITY IN COTTON
Keywords:
Electrical conductivity, Measurement, Cotton seed quality.Abstract
Investigations were conducted to relate seed exudates conductance to standard germination so as to develop a
quick and reliable test for measurement of cotton seed quality. Results showed thatcott. \11 cultiv ars differed significantly
in germination percentage and electrical conductivity. Cultivars MNH-93 and C!ivt-l09 had higher germination
percentage and less exudate conductance compared to othcr cultivars. Seeds obtained from first pick were of poor quality
than those of second pick. The exudate conductance was negatively correlated with germination (r = - 0.88**). The loss
of membrane functional integrity sel~IIISresponsible lor lower germination. These data indicate that electrical
conductivity test can provide estimates of seed quality,
