Li Tae Nam | Kim Hong Gyu [Inst. of Pomology, Sukchon Dist., Pyongan South Province (Democratic People's Republic of Korea)]
The number of leaves per fruit should be 20 to produce more 200 g than the previous in "Gilju" pear and 25 to produce more 250 g than the previous in "Wonpyong", "Haeju" and "Sinchon" pears. The yield of the fruits per tree by the fruit thinning was greatly reduced in first year as compared with control plot (non-thinning) and gradually increased after several years. But, total yield of fruits was lower than that of control. The differentiation of the fruit buds by the increasement of the fruit thinning in the variety "Gilju" pear was high by little. The weight per fruit and yield of fruits could be increased by the thinning from the end of May to the early of July
