Research paper thumbnail of Response of Spring Wheat (Triticum aestivum L.) to Induced Water Stress at Critical Growth Stages

Sarhad Journal of Agriculture, Mar 18, 2015

Th extent of yield reduction with water defiit depends not only on the magnitude of water defiit... more Th extent of yield reduction with water defiit depends not only on the magnitude of
water defiit but also on the stage of plant growth at which it develops. A pot study was conducted
during 2011-12 at College of Agriculture, Dera Ghazi Khan, to assess the effct of induced water
stress on performance of diffrent wheat varieties at critical growth stages. Thee wheat varieties viz.
Faisalabad-2008, Lasani-2008 and Kohistan-97 were manually sown in polythene lined pots. Five
water stress treatments were created by withholding the irrigation for specifid time at critical growth
stages viz. tillering, booting, anthesis and milking (grain filing), whereas a well-watered treatment
was also included during whole plant growth and development period. Th results showed that water
stress signifiantly reduced plant height, number of total tillers per plant, number of fertile tillers per
plant, number of nodes per plant, spikelet per spike, number of grains per spike, 100-grain weight
and dry matter per plant as compared with control. Wheat genotype Faisal-2008 exhibited comparatively more drought tolerance with less decrease in growth rate (18.70%); total dry matter (26.94%),
100-grain weight (23.45%) and grain yield (21.50%) as compared with all other treatments. It was
concluded that water stress induced at grain filing stage showed a signifiant impact on wheat growth
as compared with other growth stage stresses. Regarding genotypes, Faisal-2008 was least affcted by
water stress than other varieties.
