A
pot experiment was conducted to evaluate the beneficial effect of
foliar application of glycine betaine (10mM), grain presoaking in
salicylic acid (0.05 M) and their interaction on drought tolerance of
two wheat (Triticum aestivum L.) cultivars (sensitive, Sakha 94 and
resistant, Sakha 93). Water stress decreased wheat yield components
(spike length, number of spikelets / main spike, 100 kernel weight,
grain number / spike, grain yield / spike, grain yield / plant, straw
yield / plant, crop yield / plant, harvest, mobilization and crop
indices) and the biochemical aspects of grains(grain biomass,
carbohydrates, total protein, total phosphorus, ions content and amino
acids) in both wheat cultivars. The applied chemicals appeared to
alleviate the negative effects of water stress on wheat productivity
(particularly the sensitive one) and the biochemical aspects of yielded
grains. The effect was more pronounced with GB+SA treatment. This
improvement would result from the repairing effect of the provided
chemicals on growth and metabolism of wheat plants grown under water
deficit condition. In response to the applied water stress and the used
chemicals, the grain yield of the sensitive and resistant wheat
cultivars was strongly correlated with all the estimated yield
components (shoot length, spike length, plant height, main spike
weight, number of spikelets per main spike, 100 kernel weight, grain
number per spike, grain weight per plant, straw weight per plant, crop
yield per plant, harvest, mobilization and crop indices).
