| Abstract: | Based on the provenance trial of 51 seed sources at seedling stage and 21 provenances on young stands at the age of seven and with the adaptability being the main object, observations were made on the seed character, seedling growth rhythm, and drought resistance of the young stand, variation regularity of growth, etc. The result shows that it can be seen that the tree height of the south provenance is higher than that of the north provenance, with the Nishan provenance being the highest, which is 2.4 times higher than the lowest. Among the population variation of Platycladus orientalis, typical increment increases with the increase of temperature and precipitation. There appears a trend that the southeast provenance is better than the northwest,, while the stabilities and adaptation of the northwest provenance is better than those of the southeast. Therefore, the provenances were classified into seven zones. |
