تبیط الإجهاد الملحي بمنظمات النمو (kinétine و GA3) رشا على نبات القمح الصلب Simito النامي تحت الظروف الملحیة.

Abstract

This research was conducted under the conditions of the greenhouse to study the inhibition of salty exertion with growth regulators (GA3 and kénitine) on the plant of hard wheat type Simito developing under salty conditions where sea water was used of with five levels 10%. 30 %. 50 %. 80 %. 100 % including to witness , in the vegetative phase and the process of maturation. Also, the experience was sprayed with growth regulators (GA3, 50 Ppm) and (kénitine, 20 Ppm) on the vegetative collection of the plant with the category of the studied wheat. The salty exertion has effected clearly , especially in the maturation stage , which led to poor growth presented in the length of the stem , leaf surface , the shortage of the amount of chlorophyll (a , b) and the amount (ARN, ADN) with the accumulation of Proline and melted sugars. Besides the dropping of the weight of the ears and the dry weight of the vegetative and rational collection and therefore, the reduction of thousand grains presented in the yield . The contrasting of saltiness with growth regulators has proved an increase in the resistance to the wheat plant Simito of the salty exertion. And it has appeared in stimulating of the induction of Proline and sugars , and the maintain of the functioning of plant growth at all levels up to the stage of the final maturation , especially in the very high concentrations which is considered to be sometimes dead. In additions, , Gibberellic acid has showed a superiority on the Kentin in the contrasting of saltiness.
