Abstract:

Experimentation with inoculation of 8 different strains of Aspergillus niger with P solubilisation potential into plants of Piper longum showed drastic variation in growth parameters and development pattern as compared to control plants which is quite evident from the values obtained during the growth period. Aspergillus niger strain 1 inoculated plants showed maximum branching (13.25±2.65) as compared to control showing (8.4±2.77) and also showed highest leaf development with number of leaves (40.75±3.59) whereas control plants showed only (27.63±9.43) number of leaves. On the other hand, the plant height was higher in Aspergillus niger strain 7 treated plants showing (94.5±31.03) cm when compared to control plants with (57.4±16.3) cm and increase in root length was (35±9.2) cm in Aspergillus niger strain 2 which is almost double length of control plants (17.5±3.53) cm along with leaf area which is recorded to be (519.4±46.8) cm2. Most of A. niger strains improved plant growth suggesting that P solubilising strains help in P uptake in plants. Both the strains Aspergillus niger strain 2 and 8 influenced the fresh and dry leaf biomass of the plant. Maximum fruit development was observed in Aspergillus niger strain 5 (7 in 120 days, 14 in 150 days and 32 in 180 days, respectively. Again, maximum Leaf Area Ratio (LAR) is observed in plants inoculated with Aspergillus niger strain 2 having 699.1 cm2/g but maximum Relative Growth Rate (RGR) of 10.45 mg/g/day and Net Assimilation Rate (NAR) of 1.63 g/cm2/day was obtained in plants inoculated with Aspergillus niger strain 4. From the above findings, it is clear that specific strains impart growth as well as development of the plant which needs an elaborate study to confirm the mode of plant-microbe interaction.
