تأثير تراكيز و مواعيد رش حامض السالسيلك في نمو نبات الكزبرة Coriandrum Sativum L. و محتوى بذوره من الزيت الطيار

Abstract EN

The experiment was carried out in fields of Agricultural Research and Experiments Station (2) affiliated with the College of Agriculture / Al-Muthanna University during growth season 2018-2019 to study the effect of spraying three different concentrations of salicylic acid (0, 100 and 200 mg.

L-1) and spray date it at three different dates (60, 90 and 120 days after planting) on growth of Coriandrum sativum L.

and a volatile oil content in seeds.

The experiment was applied using a randomized complete block design RCBD with three replications.

The results showed that plants treated with salicylic acid (200 mg.

L-1) was significantly outperformed of dry weight shoot, the weight of 100 seeds and seed yield gave (21.76 g.

plant-1, 1.22 g and 7.79 g.

plant-1) respectively.

While, the plants treated with salicylic (100 mg.

L-1) was significantly outperformed and gave highest values of essential oil percentage (0.87% ) and essential oil yield (6.32 μl.

plant-1).

The plants that were sprayed with salicylic after 120 days of cultivation outperformed significantly in the weight of 100 seeds, seed yield and essential oil yield were gave (1.12 gm.

, 7.54 gm.

plant-1 and 5.53 μl.

plant-1).

While, the highest values were recorded in the dry weight of the shoot total (20.51 g.

plant-1) and in essential oil percentage (0.787% ) in plants that were sprayed after 90 days of cultivation.
