在食用真菌的生理和遗传育种研究过程中,常需用显微镜来观察菌丝的形态及锁状联合的有无。用水作浸液制片,菌丝细胞易收缩变形。用乳酸石炭酸液作浸液制片,具有细胞不易变形、能杀菌防腐和不易干燥等特点,但在显微镜下,由于菌体与背影反差不大,因而也不易看清。我们在工作中发 In the process of edible fungi physiological and genetic breeding, it is often necessary to observe the morphology of the hyphae and the presence or absence of the lock-like union with a microscope. Water for immersion tablets, mycelium cells easily shrink deformation. Lactic acid carbolic acid solution for the infusion film, with the cells are not easy to deformation, sterilization and anti-corrosion and easy to dry and so on, but under the microscope, due to bacteria and back contrast is not easy, so it is not easy to see. We are at work
