前言大多数商业栽培的芒果品种,特别是在印度北部有大小年结果的现象。这个令人迷惑的问题,多年来引起了科学工作者们的注意,但出乎意外,至今还没有人确切地阐明过造成大小年现象的原因。试图从实践的观点出发来解决这个问题,也没有得到满意的结果。在小年期间应用植物生长抑制剂诱导开花,获得了一些有价值的资料。但其效果各地不同。因此,认为某些植物生长抑制剂 Preface Most commercial cultivated mango varieties, especially in northern India, have year-to-year results. This puzzling question has drawn the attention of scientists for years. To my surprise, so far no one has elucidated precisely the reasons for the size-year-old phenomenon. Attempting to solve this problem from a practical point of view has not yielded satisfactory results. Plant growth inhibitors were used to induce flowering during the first year of the year, and some valuable data were obtained. But its effect is different everywhere. Therefore, consider some plant growth inhibitors
