笔者家住广州华南农业大学嵩山区，今年自家后院种植的一株番木瓜所结果实中，有～果未成熟即脱落。摇动该果时，听到内有响声，于是小心地将其切开，结果惊奇地发现果中还有一小果。番木瓜为何出现果中结果现象，这与该果成熟前的脱落是否有关系？希望能得到植物学专家的解释 The author lives in Songshan District, Guangzhou, South China Agricultural University, this year’s own backyard planting a papaya results, there is ~ unripe fruit that is off.
