Abstract:

Under scanning electron microscope, the cell of leaves of five samples of Phyllostachys heterocycla cv.pubescens in different ayes was observed, into the base of whose culms nutrient solution was injeited one year before. It was found that the stomatal density, size and degree of opening had increased greatly as compared with CK. It was useful for transpiration, raising the suction and assimilation of CO₂, enhancing the photosynthesis and respiration, increasing the metabolism and accumulating organic matter. It helped to improve yield of bamboo.
