Experimental Study on Induced Secondary Flowering of the pot-planting apple trees in Kunming Area

The secondary flowering of potted apple can improve the ornamental value and prolong the ornamental period, so as to promote the development of Apple bonsai industry. In this experiment, the morphological differentiation process of apple flower buds was observed microscopically, and the secondary flowering experiment of different varieties of potted apples in Kunming was carried out by means of whole plant defoliation and spraying monocyandiamide solution. The results showed that the flower bud of "Gala" was in the stage of sepal formation in mid August, and that of "Fuji" was in the stage of flower bud differentiation in mid August, the flower buds of "Redlove" were in petal formation stage in mid August, and the flower buds of "Shensha" and "Pinova" were in stamen formation stage in mid August. The flower buds of "Gala" and "Fuji" were in the stamen formation stage in early October, and the flower buds of "Redlove", "Pinova" and "Shensha" were in the pistil formation stage in early October; In early December, the flower buds of five apple varieties entered the pistil formation stage. In early September, "Gala", "Fuji", "Shensha" and "Pinova" successfully achieved secondary flowering through whole plant defoliation and spraying monocyandiamide solution, and "Gala", "Shensha" and "Pinova" successfully hung fruit after secondary flowering.
