Effect of planting date and plant density in the bio-activity for the leaves and seeds of Flax plant (Linum usitatissimum L.)

Abstract

Two field experiments were conducted in the field of medicinal plants belonging to College of Agriculture, the University of Basra during the agricultural seasons (2015/2016 and 2016/2017) with clay loam soil. The study included six treatments which are the combination between two planting dates (1/11 and 1/12), the cultivating with three plant densities (20, 30, 40 kg.ha-1) and their interactions in the activity of methanolic extract for the leaves and seeds of the flax plant (Linum usitatissimum L.) as Anti-inflammatory and antioxidant. The highest anti-inflammatory effect in vitro for the methanolic extract for the leaves and cultivated seeds of the plant at 1/11 with a plant density of (20 kg.ha-1), which amounted of (97.80, 94.78, 98.0, 96.3), respectively, and anti-oxidant activity amounted to (98.04, 95.67, 66.58, 55.11%), respectively. Treatment with Flavonoids for the leaves or seeds of flax plant had an anti-inflammatory effect in vivo that was close to the activity of Diclofenac drug.
