实践证明,用低剂量γ射线辐射处理一些作物和种子,其增产幅度可达10—20%。而在食用菌生产中作用如何?目前报道甚少。为此,我们对佛罗里达和凤尾菇菌种进行了不同照射剂量的试验,现将结果报告如下:材料和方法(一)试验一:培养料配方为胡豆壳50%、锯木屑40%、玉米粉8%、石膏2%,含水量60%,用聚乙烯塑料袋装料,每袋装料1kg(干重),在1.5kg/cm~2下灭菌1.5小时。再将菌龄28天的佛罗里达麦粒种,用~(?)Co—γ射线照射,剂量分布为1.9、3.8、5.7、7.6、9.5戈瑞(Gy)。照射后立即在严格消毒的接种室接入料袋内,接种量为料干重的4%,设3次重复,18个小区,每小区干料5kg,以未照射的为对照。
Practice has proved that the use of low-dose γ-ray radiation treatment of some crops and seeds, the rate of increase of up to 10-20%. In the production of edible fungus how? There are very few reports. To this end, Florida and Pleurotus ostreatus strains were irradiated at different doses, the results are reported as follows: Materials and methods (a) of a test: training materials formula 50% walnut shell, sawdust 40%, corn Powder 8%, gypsum 2%, water content 60%, with polyethylene plastic bag, each bag charge 1kg (dry weight), 1.5kg / cm ~ 2 sterilization 1.5 hours. The 28-day-old Florida wheat seeds were irradiated with ~ (?) Co-γ rays and the dose distribution was 1.9, 3.8, 5.7, 7.6 and 9.5 Gy. Immediately after irradiation in the strict disinfection of vaccination room access bag, inoculum size of 4% of dry material, set 3 times, 18 cells, dry material per cell 5kg, not irradiated as a control.
