Phytohormone-like activity of Volvariella volvacea (Bull. Ex Fr.) Singer

Results revealed the potential hormonelike activities of V. volvacea crude and hot water extracts influencing the growth and development of rice, corn and radish. The effect of V. volvacea (9.87) in the number of roots initiated in rice is comparable to those treated with auxin (11.23) and gibberellin (12.40) while in corn, V. volvacea (9.77) was statistically similar to gibberellin (9.03). In addition, the length of corn roots treated with V. volvacea crude extract (98.07mm) and V. volvacea hot water extract (93.65mm) exhibited auxin (87.74mm) and gibberellin (100.08mm) like activity. Meanwhile, auxin like activity was observed in rice treated with V. volvacea crude extracts with the length of second leaf of 109.39mm and 98.29mm, respectively. Whereas for the secondary leaf of corn, the effect of V. volvacea crude extract (87.89mm) and hot water extracts(84.17mm) were comparable to the effect of gibberellin (82.95mm). Cytokinin like activity was observed in V. volvacea hot water and crude extracts through rice coleoptile and biomass of radish assay with 16.88mm coleoptile length and cucumber cotyledon biomass of 0.164g. Lastly, the observed total chlorophyll content ranged from 65.12% to 192.67% which indicated the greening effect of V. volvacea extracts.
