Abstract

<P>PROBLEM TO BE SOLVED: To provide a flowering plant cultivating method capable of cultivating a flowering plant of a new shape, demanded in a flowering plant market. <P>SOLUTION: This flowering plant cultivating method comprises cultivating a flower which has whole new appearance by controlling the shape of spike axis and promoting growth of flower petals in a process of pinching the growth point of inflorescence axis in a stage between budding of flower buds and blooming. The flowering plant obtained by the method is also provided. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a method for cultivating florets having a new appearance by a simple method and a floret obtained by the cultivation method.

  In recent years, gardening and flower arrangements have become popular. Along with this, the needs of the flower market have also diversified, with unprecedented colors, new types and varieties of appearance, varieties that can be shipped at a high unit price without cracking, varieties with a large number of annual flowers, A wide variety of flower buds such as spray species are required.

Therefore, in order to meet the needs of various markets, breeding has been widely carried out by crossing, etc., and the method of cultivating flowers with different appearances by releasing the constraint on the outermost cocoon of the cocoon Offers new varieties of flower buds.

  In the flower market, diversifying needs are demanding unique colors and new types of flowers.

  Therefore, an object of the present invention is to provide a method for cultivating florets by a new method that has been simple but has never been performed, and a floret obtained by the method.

  The flower cultivating method of the present invention is a new method by controlling the growth of the inflorescence axis and promoting the growth of the petals by the step of pinching the growth point of the inflorescence axis at the stage from just after arrival to the flowering stage. It is characterized by growing into a flower bud with an appearance.

  The florets of the present invention are obtained by the method for cultivating florets according to the present invention.

  Moreover, unless the time of pinching by the said cultivation method is performed at an appropriate time, it will not be possible to obtain a flower floret having an appearance that is acceptable as a product.

  Conventionally, if the inflorescence axis and the flower bud growth point are damaged by insect damage, etc. during the growth stage of the floret, the normal growth of the petals is hindered, and the commercial value of the floret disappears due to the inability to bloom or deformation. It is not discarded.

  The method of cultivating florets of the present invention is to pinch the growth point of the inflorescence axis, which has conventionally been a taboo, by artificially pinching at an appropriate stage immediately after the arrival to the flowering stage, By controlling the growth of the remaining inflorescence axes, it was possible to promote the growth of inflorescence axes and petals of preferred shapes, and to provide florets with a new type of appearance not on the market.

  According to the method of the present invention, the inflorescence axis is shortened, and the petals become large and dense, so that it looks like a flower having a round shape as a whole, and has a completely different appearance from the conventional one.

  By the method of the present invention, it is possible to confirm that the nutrients and energy spent for growth can be turned into flowers, and that the plants have a thick petal and thick floral pattern and become strong flowers due to the healing ability of the plant to recover the damaged part. It was.

  As a result, the effect of extending the longevity can be obtained, the shape of the petals blooming on the inflorescence axis can be confirmed and shipped, and there is no loss in terms of quality control. I was able to get a long flower holding period.

  An example of the subject flower in the present invention is a spike-like flower having an inflorescence axis as shown in FIG. 1, and a large number of flowers 1 are florets that attach almost equally to the inflorescence axis 2.

  2 (a) to (c) are diagrams schematically showing a normal growth process of an inflorescence of spikes, inflorescence axis 2 growing upright, (a) at the time of arrival, (b) ) Represents an initial flowering stage in which the inflorescence grows and buds swell from the lower stage, and (c) represents a stage in which the inflorescence extends and blooms in order from the lower stage, and becomes an elongated flower.

  Specific examples of florets having such a structure include, but are not limited to, the Brassicaceae genus Araceae stock, the buttercup delphinium, the scorpionaceae snapdragon, and the like.

  Moreover, the flower which becomes object by this invention is a flower of an infinite inflorescence, and the form of an inflorescence is not ask | required.

  FIGS. 3 (a) to 3 (b) are diagrams schematically showing the growth process in the case where the process according to the present invention is performed on the flower buds of spikes, and FIG. 3 (a) is a figure that pinches the growth point 5 of the inflorescence. At the time of cocoon, (b) shows the stage where the inflorescence axis 2 can only grow halfway, and the petals have become larger and dense, resulting in a rounded floret in appearance.

  The appropriate time to pinch the growth point of the inflorescence is preferably before the color changes to the wrinkle after arrival, too early to grow the inflorescence, too late to extend the inflorescence too much and the petal Neither is sparse and neither grows into an acceptable appearance as a product.

  In the Examples, comparison is made using a Brassicaceae genus Araceae stock. FIG. 4 shows a stock with a normal commercially available shape, and the inflorescence axis is a long and elongated flower.

  On the other hand, FIG. 5 shows an embodiment of the present invention, which is a round flower having a completely different appearance as compared with a normal elongated flower.

It is the figure which represented typically the structure of the floret of the spike-like inflorescence which has the inflorescence axis 2, and 2 represents the petal which blooms along an inflorescence axis. It is the figure which showed typically the general growth stage after the flower bud differentiation in a spike. It is the figure which showed typically the growth stage after performing the process by this invention. It is the usual commercially available form of Brassicaceae stock. It is the flowered form of the Brassicaceae genus Araceae which implemented this invention.
