Morphological responses of a high yielding groundnut cultivar (Arachis hypogaea L. cv. K-134 ) under water stress

K.V. Madhusudhan, C Sudhakar


The present study was undertaken to ascertain the morphological responses of a groundnut
cultivar K-134, under different water stress regimes characterized as control, mild, moderate
and severe stress represented by 100, 75, 50 and 25% soil moisture levels respectively for
eight days. Root length increased over control at mild, moderate stress treatments and
inhibited at severe stress conditions on all days of sampling. Severe stress treatments had
caused significant inhibition in shoot growth on day-4 and 8. The fresh and dry weights of
roots and leaves and leaf area decreased over control in all stress treatments except under mild
stress on day-4. The changes in theses parameters were dependent on stress severity and
