In this paper, the cutting seedlings of P. kangdingensis, which age of 300-500 years old and diameter at breast height (DBH) was greater than 1m were used as experimental materials, and the anatomical structure of the leaves and stems of seedlings were studied by the method of paraffin section. The pot experiment was conducted by way of weighing to control water content in soil, that was to weigh the pot in every afternoon and supplement the consumption of water to keep it about 60% of the maximum field water capacity, and the control was kept about 80% of that. The water control test lasted for about 3 months and plant tissues had changes in the physiological structure. Then, the samples were collected and measured by paraffin section method. The results showed that, under drought treatment, the thickness of palisade tissue and sponge tissue in the leaves of old P. kangdingensis cutting seedlings increased significantly, while the thickness of upper and lower epidermis, the cuticle, and the leaves thickness increased slightly. Besides, the structure of the transport tissue decreased significantly on the stem, indicating that in a certain degree of drought, the morphological and anatomical structures of P. kangdingensis could be adjust accordingly to adapted to drought and then have strong drought resistance.
