How to choose flower seeds

Many people like to plant some flowers and plants in their spare time, which becomes that problem in planting. I will share it with you below.

I. several principles to be followed in the selection of flower seeds

First, the variety of choice should be suitable for the local aesthetic habits. There are different views on the aesthetics of flowers in different places, including flower color, flower size and some special customs. Second, the selected varieties should correspond to the seasons. Some varieties have strong seasonality, such as kale, daisy, marigold, pansy, etc., which are suitable for sowing in autumn; pansy, cockscomb, Catharanthus roseus, thousand-day red and so on are suitable for sowing in spring and summer; while a string of red, four seasons begonia, marigold, hundred-day grass, petunia and so on can be sown in four seasons as long as the conditions are suitable. Third, it is necessary to select seeds according to their own production conditions and technical level. For example, the conditions for raising seedlings of herbaceous flowers in the first generation of hybrids (that is, F1 generation) are higher, and generally need to be raised in protected areas. Especially in off-season cultivation, more attention should be paid to the control of temperature, humidity and light conditions. Begonia, Petunia and so on, their seeds are small, without skilled sowing techniques and suitable seedling conditions, it is difficult to achieve the ideal effect.

Second, to select flower seeds, you should first determine the selection period.

In flower cultivation, it should be combined with different types of flowers and the actual needs of cultivation, can be selected in the following periods, in order to abandon the inferior and select the best. One is the choice of seedling stage. When transplanting or planting, we should make a selection according to the correlation of plant characters, retain the plants with excellent typical characters, and eliminate those plants whose excellent characters are not obvious or have segregation and variation. The second is the choice of early flowering stage. The breeding of grass flower varieties should take advantage of this period to remove impurities and disadvantages, so as to effectively maintain the excellent characters of early flowering. The third is the choice of flowering period. The full flowering stage is the selection period for determining the typical characters of flowers. the method of mixed selection is generally adopted, that is, according to the ornamental and economic characters of the cultivated flowers, the plants with high quality flower color or excellent characters are selected from a primitive mixed population or variety, and compared with the standard varieties the following year, so that after one or more selection, the plants with good characters that the offspring are no longer separated can be selected.

On the other hand, some herbaceous flowers, such as cockscomb, goldfish grass, melon and leaf chrysanthemum, pansy, carnation and so on, are prone to natural hybridization among varieties, resulting in confusion and degradation among varieties. When selecting the seeds of this kind of flowers, special attention should be paid to the isolation measures among varieties to prevent powder stringing and make future generations mutate. For some chrysanthemum grass flowers, such as Persian chrysanthemum, melon-leaf chrysanthemum, etc., the flowers are composed of ligulate flowers and tubular flowers. When selecting a single plant of this kind of flowers, special attention should be paid to the color of unconspicuous tubular flowers. if a single plant is kept solely according to the color of the eye-catching tongue flower, it will often lead to the gradual degradation of fine flower color.

Third, choose the parts that should be selected for flower seeds

From the point of view of seed selection, the seeds produced by inflorescences or florets in different parts of the same plant have different degrees of typicality of retained varieties. The general rule is that flowers blooming on plants can produce better seed offspring than late flowers, such as early flowering, large flowers, colorful flowers, and so on. Take cockscomb as an example: the seeds produced in the middle and lower part of the central inflorescence are the best. The seed setting rate of the middle and lower part of the raceme is high. There are also hundred-day grass, thousand-day red, Scutellaria barbata, purple jasmine and so on.

For some flower varieties that grow on the main branches and side branches, such as Persian chrysanthemum, petunia, goldfish grass, etc., the seed weight in each fruit generally decreases from the bottom up, and the germination rate decreases from the bottom up. Their offspring also have significant differences in growth, so it is necessary to choose the seeds produced by the lower flowers. Even if the seeds in different positions of the same inflorescence, the degree of retention of variety typicality in their offspring is also different. Such as chrysanthemum, marigold, cornflower and other chrysanthemum flowers, the seeds planted on the edge of the disk can maintain their excellent characters. The seeds formed in the center of the disk are not strong and the fine characters are not ideal, so it is not suitable to leave seeds for use.
