تأثير الإجهاد المائي و السماد الورقي Foltron في نمو نبات حلق السبع الشجيري Adhatoda vasica (L.)‎ Nees و إنتاجه لفويلد vasicine

Abstract EN

This experiment was conducted in Biology Department - College of Science - University of Al-Qadisiya that included field experiment from the period of 1/4 to 1/8/2013.

The goal of the experiment was to Study the effects of water stress and foliar fertilizer (Foltron) on growth and production alkaloid vasicine of Adhatoda vasica (L.) Nees , Experiment included twenty four transplants (age of one month and 8 cm height) that were transplanted in plastic pots with 10 kg.

soil (one transplant per pot) in 1/4/2013 .

Pots were filled with sandy soil and peatmose 2:1 v/v .

Plants Irrigated with two levels 50 and 25% of field capacity .

Foliar fertilizer was used at three concentrations of 0, 3 and 6 ml/L that sprayed twice on plant shoot till complete wetness during 15/4 and 1/6/2014 The results showed that increasing level of water stress caused a significant decrease in dry weight shoot and root, leaf area, total chlorophyll and the percentage of nitrogen, while the cause of an increase in the concentration of proline from 0.141 to 0.151 mg/gm and alkaloid vasicine in the leaves from 42.59 to 57.88 μgm/gm and in roots from 53.84 to 71.25 μgm/gm .

As for the increase in the concentrations of foliar fertilizer, it is the cause of a significant increase for all studied characters except for a significant decrease proline .
