Combined Use of Two Trichoderma Strains to Promote Growth of Pakchoi (Brassica chinensis L.)

Trichoderma spp., which widely exist in nature, are always used as plant growth-promoting stimulants. However, there is little reporting about the combined use of strains to promote growth plants. We explored two different (Trichoderma atroviride LX-7 and citrinoviride HT-1) a mixture on effects pakchoi. In this study, vitro-promoting traits were determined, six treatments used: T. LX-7, HT-1, mixtures these (1:1, 1:2 2:1) no inoculation seed germination pot experiment. The results showed that T.atroviride HT-1 had ability siderophore indol acetic acid (IAA) production, capacity for potassium solubilization. highest percentage (GP), energy (GE), index (GI), vitality (VI) radicles plumules was observed + (1:1) combination, biomass quality plants (1:2) (followed by single or strain inoculation), while lowest values obtained untreated seeds On basis greater benefits pakchoi, making formulation attractive future field applications.
