تأثير الحرارة المرتفعة و رطوبة التربة في إنبات بذور الداتورة Datura innoxia Mill Echinochloa colonum (L.)‎ Link.أبوركبه Cassia italica (Mill.)‎ Lam. Ex Steud و العشرق الأصفر

Abstract EN

Seeds of three common weeds in Yemen: Datura innoxia, Echinochloa colonum and Cassia italica were heated for up to 7 days at 40, 50, 60 and 70 °C in dry (3.15% moisture) and moist (22% moisture) soils, to determine the temperature-time lethal effect on the weed seeds.

The three species tested showed different responses to the effect of temperatures either in the dry or moist soil; however it was noticed that the treatments were more effective in the moist soils.

The temperature-time tolerance of the three species in moist or dry soil followed the order: Cassia italica "Echinochloa colonum" Datura innoxia.
