University of Guilan Iranian Journal of Seed Sciences and Research 2476-3780 1 2 2014 09 23 The effect of seed biopriming by Piriformospora indica and Trichoderma virens on the growth, morphological and physiological parameters of mung bean (Vigna radiate L.) seedlings The effect of seed biopriming by Piriformospora indica and Trichoderma virens on the growth, morphological and physiological parameters of mung bean (Vigna radiate L.) seedlings 67 78 1327 FA Neda Salimi Tamalla Fahimeh Seraj Hemmatollah Pirdashti Yasser Yaghoubian Journal Article 2015 10 24 Nowadays, the use of biofertilizer is steadily increasing in sustainable agriculture, therefore the present study was aimed to evaluate the effect of seed biopriming by Piriformospora indica and Trichoderma virens on the growth, morphological and physiological parameters of mung bean (Vigna radiate L.). Experiment was conducted as completely randomized design with three replicates in 2014. Treatments were included four levels of biopriming (control, inoculation by P. indica or T. virens and dual inoculation by P. indica and T. virens). Seeds of mung bean were sown in sterile soil and grown for four weeks and then some morphological, growth and photosynthetic pigments parameters were determined. Results showed that seed biopriming by Trichoderma, P. indica and dual inoculation increased plant height (4, 8 and 2 %, respectively) and root length (18, 31 and 13 %, respectively) as compared to the uninoculated control. However, the increase was significant only for P. indica inoculated seeds. Furthermore, shoot fresh and dry weights increased when mung bean seeds inoculated by both fungi. The maximum increase in stem, shoot and plant dry weights (5, 3 and 2 times of control) were recorded when seeds inoculated with P. indica. Also, inoculation of seeds by P. indica improved chlorophyll a, b, a+b contents (nearly 8, 15 and 9 %, respectively). In conclusion, it seems that seed biopriming of mung bean by growth promoting fungi particularly P. indica positively improved the growth attributes in early growth stages.
