Potential Endophytic Bacteria for Increasing Paddy Var Rojolele Productivity
Paddy var Rojoleleis asuperior paddy come from Klaten that released by Department of Agriculture in 2003. Its superior properties are resistant to pests leaf hoppers, fluffier, and fragrant. To increase the productivity of paddy that are of ten used by farmers is to use chemical-based fertilizers. The use of these chemicals will effect to adisruption of ecosystem balancing, reduction the amount of soil microflora which essential forplants. Endophytic bacteria are symbiotic microorganisms living within plant tissues, and does not cause negative effects on the host plant. Endophytic bacteria have a capability increasing crop productivity by producing growth hormone, contributes to plant health, and as bio-control agents. Some endophytic bacteria which contribute to plant growth are: Pseudomonas sp., Enterobacter sp., Staphylococcus sp., Azotobacter sp., And Azospirilum sp., Whereas endophytic bacteria that contribute to the health and plant protection several of them are: Pseudomonas sp., Serratia sp. ,Clavibacter sp., and Bacillus sp. This study was conducted to investigate potential of endophytic bacteria to increase Paddy var Rojolele productivity based on its ability to produce extracellular enzymes and resistance to multiple types of antibiotics. The method were endophytic bacteria isolation from three Paddy varRojolele plants, extracellular enzymes detection and antibiotic resistance testing to chloramfinekol, ampicillin and kanamycin. As the result, 43isolateswere isolated from Paddy var Rojolele. Four isolatesamong them havethe ability to produce extra cellular enzym esandresistant toampicillin, kanamycin, and chloramfinekol. Extra cellular enzyme production capability and resistance to antibiotics makes endophytic bacteria are potentialto improveplant health and also asbio-control agentwhich then willaffect to the productivity of rice. To further ensure its potential to plant, more research is needed.
