The invention provides a method for identifying carnation chromosome number by bud, comprising: obtaining bud anther, ovary wall and corolla tissue, pre-treating ice water mixture, fixing by stationary liquid, dyeing, dissociating with hydrochloric acid, tabletting and microscopic examining. Compared with the traditional method that a root tip tissue is used for chromosome tabletting, the invention solves the disadvantages of few visual filed cells, difficult microscopic examination and poor chromosome dispersion during root tip chromosome tabletting, and overcomes the problems of long rootage period for carnation cutting seedling and time and labor wasting for cutting; compared with stem tip chromosome tabletting, the invention overcomes the interference problem of non-meristematic cell or reserve substance or secretion, chromosome tabletting can be realized only by using buds, which does not damage plant growing state and has convenient material resource; in addition, a plurality of metaphase cells exist, so that the difficulties of small carnation chromosome, huge quantity and hard counting of the chromosome can be solved. Thus, when plants bloom, the effective method is that the bud is used for chromosome tabletting.

The method comprises the following steps that after the dianthus chinensis plants bloom for the first time and are pruned and stumped at the positions away from the ground for designated height in a designated time period; residual branches are cleared, and a designated depth of water is watered; the roots of the dianthus chinensis plants grow out lateral buds again in a first designated maintenance time duration; lateral buds develop mature after a second designated maintenance time duration; lateral buds secondarily bloom after a third designated maintenance time duration. By adopting the method for promoting secondary blooming of the dianthus chinensis plants, it can be ensured that secondary blooming of the dianthus chinensis plants can be promoted without pinching processing after flower withering, and the ornamental value of the plants is embodied again.

The invention discloses a longan gene DlGRAS34, a protein and an application of the longan gene DlGRAS34 and the protein in regulating and controlling flowering of plants. A cDNA nucleotide sequence of the longan gene DlGRAS34 is shown as SEQ ID No.1. The full length of an open reading frame of the longan gene DlGRAS34 is 1578bp, 525 amino acids are encoded, and the longan gene DlGRAS34 has a typical GRAS structural domain and a DELLA structure and belongs to GRAS protein. A qRT-PCR result shows that the gene has tissue expression specificity, has the highest relative expression quantity in pericarp, and has the second relative expression quantity in stem, leaf and flower organs; expression is down-regulated in the early flowering induction stage of 'Sijimi' longan, and expression is up-regulated in the later flowering stage of 'Shixia' longan. A transient expression result of the arabidopsis protoplast shows that a fluorescence signal is mainly concentrated on a cell nucleus. A transgenic arabidopsis thaliana result shows that a DlGRAS34-overexpressed transgenic plant shows a late flowering phenomenon that a wild type plant blooms in about 27 days, and a transgenic line blooms in 32-35 days; and meanwhile, rosette leaves become large, and plants become short. The results show that as a typical transcription factor, the protein coded by the DlGRAS34 is located in a cell nucleus, plant flowering is negatively regulated, and the overexpression of the DlGRAS34 gene can significantly inhibit plant flowering.
