تأثيرات تداخل فترات الجفاف و مستويات مختلفة من النتروجين في النمو و محتوى أوراق نبات الحنطة من الكلوروفيل و البرولين و الماء النسبي

Abstract EN

This study was conducted under glasshouse condition to indicate the effects of drought condition (0.0, 24, 48 and 72 hr.

after temporary wilting point) and different levels of nitrogen on growth and some physiological aspects of five wheat cultivars (IPA 970082, VEE (S), IPA 970110, ACSAD 881, and ACSAD 907).

The main results showed that applying nitrogen to the soil as urea has decreased negative effects of drought on plant growth and some physiological aspects.

Treatment of 30 ppm nitrogen result in significant increase in shoot and root system dry weight, plant hight, root system length, chlorophyll content and relative water content of leaves tissue, while proline accumulation had significantly increased in the leaves of plants when nitrogen was applied at the level (60) ppm.
