Growth promotion persistence of Alamo in greenhouse by PsJN inoculation. The seedlings were inoculated with PsJN and grown in vitro for one month, then transferred to 4-gallon pot with 5 plants/pot and grown in greenhouse for two months. Dry weight was determined after samples were dried in oven at 65°C for one day. Sample number was 25, and ** means significant difference at 0.01 level between PsJN and control using student T-test.
