Proceeding of the Symposium on the Improvement of Breeding and Production Techniques of Legumes, Tea and New Special Crops 2000
本試驗探討不同有益微生物對茶苗生育之影響。Bacillus substilis (BS)原液含菌數為10℃fu/ml，Streptoinyces saracetice (SS)原液含菌數為10℃fu/ml，將菌液稀釋成四種濃度，並以噴水（CK）當為對照，定期噴施於青心烏龍及鐵觀音穴植管苗中，生長一年後調查其生育的情形。青心烏龍茶苗施用BS2000x、1000x、500x及200x之成活率分別為97.8％、90.6％、92.4％及89.7%，施用相同濃度之SS茶苗成活率分別為77.0％、77.0％、76.3％及65.9%，對照組之成活率為77.7%；噴BS各濃度茶苗之株高平均皆達29cm以上，葉數達14葉以上，穗鮮重達5g以上。根鮮重達2.15g以上，茶苗生長明顯的較對照組為佳；青心烏龍噴SS茶苗生育亦與CK生長差異不大，尤其噴SS 2000x對茶苗成活率反而有被抑制的現象。鐵觀音施用四種濃度之BS茶苗成活率在10.7％至5.4％之間與CK之7％差異不顯著；施用SS各濃度之茶苗成活率在43％至26.9%，茶苗株高在26.3至44.3cm，茶苗生育明顯較CK為佳。
Effects of Different biogents on the growth of tea cuttings in dibbling tubes were discussed in this studies. Four concentrations of Bacillis susbtilis (BS) stock solution containing 10cfu!ml, Streptomyces saracetice (SS) stock solution counting lOscfulml and control were sprayed on cultivars Chin-shin Oolong and Tiee-kuan Yin once every ten days. Survival rate, length of shoots, number of leaves, weight of shoots and width of stem were recorded after 360 days cutting. In cv. Chin Shin Oolong, the survival rates of tea cuttings spraying with 2000, 1000, 500 and 200 dilution rates of BS stock solution and check were 97.8%, 90.6%, 924%, 89.7% and 77.7%, respectively. However the survival rates of tea cuttings spraying with 2000, 1000, 500 and 200 dilution rates of SS stock solution and check were 77.0%, 77.0%, 76.3%, 65.9 and 77.7%, respectively. Spraying BS solution had better effects on subsequent growth of tea cuttings than SS solution. Conversely, in cv. Tiee-Kuan Yin, SS solution had better effects on the growth of tea cuttings than BS solution.
