USING OF MOLYBDENUM TO IMPROVE SOME OF ANATOMICAL CHARACTERISTICS AND MITIGATION INDUCED DROUGHT DAMAGE BY PEG-6000 IN MUNG BEAN SEEDLINGS (VIGNARADIATE L.)

Abstract

A laboratory experiment was carried out in seed technology lab in department of field crop sciences/ College of Agriculture-University of Anbar in order to study effect of molybdenum in priming mung bean seeds (cv Local) under effect of induced drought by using PEG-6000. Four Mo concentrations were used 0, 15, 30, 45 mg L-1 while PEG-6000 was also used to get water stress of 0, -0.4, -0.8, -1.2 bar in medium of seed germination. The experiment was laid out RCBD with four replications for each treatments. The important results of the study showed that Mo application with concentration of 45 mg L-1 improved germination and growth of mung bean characteristics including plumule length (5.41 cm) and xylem dimensions in radical (2 mm2), Plumule epidermis (2.5 mm2) and xylem in plumule (3.5 mm2). However, the application of 15 mg L-1 improved radical length (6.47 cm), Radical epidermis (5 mm2), radical xylem dimensions (3.5 mm2) and phloem in plumule (3.5 mm2). It can be concluded from this study that the increase in water stress led to reduction in lab performance of germination and growth of mung bean seedlings, while the application of Mo enhanced it through the activation of some growth characteristics therefore it can be recommended using Mo in order to support growth and production of different crops.
