Abstract: Basing on work of papaya (Carlca papaya L.) ln the dry-and-hot river region in Jinshajiang, the authors have been observing for the performance and the analyesing of the fruits physlcs and chemistry ln the last few years (1985～1988). The root system was malnly dlstributen beeween 10 to 70 centlmetres under the soll surface. The helght and trunk area of the plant had only one growth peak every year, and theirs growth rate was dlrectly correlatlve wlth the temperature and relative humldlty, but was not dlrectly correlative with the day hours. The volume of the frult had two growth peaks every year, and its growth rate was not directly correlatlve with the temperature, relative humidlty and day hours. The nutrient compositions in the fruit showed saliently that the water and vitamin C were more and the holding acid soluble solid were less. The welght of one fruit was lighter. There existed much difference on the performance of the varieties or strains.
