BACKGROUND
Trichoderma sp. SL2 has been previously reported to enhance rice germination, vigour, growth and physiological characteristics. The use of Potato Dextrose Agar as carrier of Trichoderma sp. SL2 inoculant is not practical for field application due to its short shelf life and high cost. This study focuses on the use of corn and sugarcane bagasse as potential carriers for Trichoderma sp. SL2 inoculants.
FINDINGS
A completely randomized design was applied for this study. Trichoderma sp. SL2 suspension mixed with corn and sugarcane bagasse were used as treatment mixture in soil. Growth parameters including rice seedling height, root length, wet weight, leaf number and biomass were measured and compared to control. The results showed that Trichoderma sp. SL2 mixed with corn significantly enhanced rice seedlings root length, wet weight and biomass compared to Trichoderma sp. SL2 mixed with sugarcane bagasse and control.
CONCLUSION
Corn can be a potential carrier for Trichoderma spp. inoculants for field application.
背景
先前已有报道称木霉菌株SL2可提高水稻的发芽率、活力、生长及生理特性。由于马铃薯葡萄糖琼脂作为木霉菌株SL2接种剂的载体保质期短且成本高，因此不适合田间应用。本研究着重于使用玉米和甘蔗渣作为木霉菌株SL2接种剂的潜在载体。
研究结果
本研究采用完全随机设计。将木霉菌株SL2悬浮液与玉米和甘蔗渣混合后用作土壤中的处理混合物。测量了包括水稻幼苗高度、根长、湿重、叶片数量和生物量在内的生长参数，并与对照进行比较。结果表明，与木霉菌株SL2与甘蔗渣混合及对照相比，木霉菌株SL2与玉米混合显著提高了水稻幼苗的根长、湿重和生物量。
结论
玉米可作为木霉菌接种剂田间应用的潜在载体。
