| الملخص: أجريت هذه الدراسة على نبات القمح Triticum aestivum حيث نميت بعض البادرات فى تربة فقط وهذه استخدمت کشاهد, أما فى حالة البادرات النامية فى تربة محسنة بالبوليمرات فقد کانت نسبة البوليمر للتربة50:50% و 25:75%على التوالى.عرضت البادرات النامية لدورتين من الجفاف و ترکت لتنمو. سجل الطول الکلى للنبات ثم أطوال کل من المجموعى الخضري والجذرى کما قدر الوزن الرطب,الجاف, النسبة المئوية للمحتوي المائى و اليخضور. أوضحت نتائج هذه الدراسة أن للبوليمرات دوراً هاماً فى تحفيز نمو بادرات القمح النامية فى ظروف جفافية, بالإضافة الى المحافظة على رطوبة التربة. أظهرت النتائج المتحصل عليها أن اضافة البوليمرات للتربة يحسن من خصائص التربة ونمو النبات . This study carried out on wheat plant Triticum aestivum.Some wheat feeling were germinated in soil (control) while other feeling germinated in improved soil and polymer with percentage 50 :50 and 25 :75 respectively. Growing seedling were exposed to two drought cycles then left to grow. Total plant length and length of shoot and root were recorded. Dry weight, fresh weight, relative water content and total chlorophyll were estimated. the result of this study referred that, water hydro gels had played an important role to improve wheat seedling growth under drought conditions. In addition, maintained soil moisture. The results of this study indicate that application of polyacrylamide improved the physical properties of dry soil and enhanced plant growth. | ||
