Effect Of TRIA,VB₁ And KH₂PO₄ On Friutbody Yield And Quality Of Volvariella Volvacea

The experiment in "311-A"opimization combined design was used to study the effect of different combination of TRIA VB1 and KH2PO4 on the growth , friutbody yeild and quality in Volvariella volvacea. The results were as follows:1. The appropriate concentration of TRIA VB1 and KH2PO4 can shorten hypha-inducing ,facilitate the hypha growth and finally increase the yield and quality of Volvariella volvacea with the higher concents of protein and vitamin C .2. The hypha growth and friutbody development of Volvariella volvace were promoted significantly with the appropriate ratio of TRIA VB1 and KH2PO4 reflecting the comprehensive effects of the the three factors .3 .At the stage of hyphae growth ,the combination with 1.00mg.L-1 TRIA, 0.08mg.L-1 VB1 and 1.0% KH2PO4 was the best one. which made hypha grow fastest (the speed of hypha growth was 12.21mm per day).The optimized combination as for the yeild and quality of Volvariella volvace was the 1.00mg/L TRIA , 0.08mg/L VB1, 1.13%KH2PO4, which resulted in the yeild with 128.4g.bag-1 (higher than control by 34.41 g.bag-1), the biologic efficiency with 42.8% (higher than control by 11.4%), the protein content with 39.00% (higher than control by 7.78%) and the vitamin C content with 3.22‰(higher than control by 0.94‰)...
