How to tell if the genes of a gentleman s orchid are stable

To determine whether the genes of a strain of Monarch Orchid are stable or not, it takes a long time to observe.

Orchids are heterozygous and have different characteristics at different stages of growth. For example, the leaves that grow in summer are thinner and longer than those in winter, and the leaves that grow with the arrows are wider, thicker, harder, brighter, and ...... veined and convex than other leavesWait.

Generally speaking, there will be more or less changes from the seedling stage to the first flowering of the Junzi Orchid, and from the first flowering to the third flowering of the Junzi Orchid. This change is naturally relatively small in genetically stable Junzi orchid.

Superior mutation refers to the transformation of some excellent recessive genes into dominant genes at different growth stages, and the performance is better than the initial stage. This kind of genetic change is what people expect, and the deterioration is the opposite, and such a change can only be said to be a bad result of crossbreeding.

It takes at least 7 to 8 years to observe whether the genes of a junzi orchid are stable, and it is also necessary to refer to the consistency of its seed and seedling offspring and the consistency of its pollen to pollinate the offspring ......of other flowersWait a minute. It's not easy to get a genetically good and stable orchid, but it's a lot of fun!

How to judge whether the Junzi Lan Cailan gene is stable? Judging from the color of the leaves and the center of the leaf, don't be fooled when you buy it!

The plant shape of the orchid is straight, the leaves are symmetrical, the ants or are neatly arranged, and the four seasons are verdant. The advantages and disadvantages of Junzi orchid varieties are mainly identified from two aspects: leaves and flowers.

1) Identify the advantages and disadvantages of Monarch Orchid from the leaves. Identification of the advantages and disadvantages of young varieties that have not yet flowered: look at the width.

The ratio of leaf length to width below 4 1 is the upper grade, 5 6 is the middle grade, and more than 7 is the general variety. Look at the veins. The veins are obviously raised in the shape of "Tian" or "Day", up to more than millimeters, and its pulse distance is also large, the vision is clear, and the sense of touch is obvious for the top grade.

Look at the thickness. The blade thickness of the best varieties can reach more than 2 mm. Look at the brightness.

The shiny and shiny ones are the top grades, and the dull ones are the medium grades.

role="Figure Orchid identifies the advantages and disadvantages of adult Orchid varieties: The leaf width of more than 10 cm is the famous product, the 8 9 cm is the top grade, and the 6 7 cm is the middle grade. The leaves and the aspect ratio of about 4 1 are famous products, 5 6 1 are top grades, and 7 1 are medium grades.

The leaf color is oily and bright, and the mesophyll between the transverse veins is emerald green, which is the top grade; The mesophyll is grass-green, and the medium grade is medium. The leaf veins are longitudinally raised, the veins are obvious and the intervals are very wide, and the characters of "Tian" are famous; The transverse veins are obvious, the spacing is wide, but the left and right are not neatly staggered; The transverse veins are obvious but the spacing is medium. The leaves are thick (generally more than 2 mm) and leathery, which is the best orange; The thinner blades are of medium grade.

The leaf end is round and blunt, slightly abrupt, and the tip is reversed upwards for the top grade; The leaf end is acute, and the tip is reversed downward. The leaf posture is straight, it stretches straight at an angle of 45 ° to the oblique upward, the length of the upper and lower leaves is the same, and the fan-shaped arrangement is a famous product; The oblique angle is slightly larger, the length of the blades is about the same, and the left and right arrangements are basically in a straight line. The leaf posture is oblique, the vertical arch, and the uneven length of the leaf is of medium grade.

2) Identify the advantages and disadvantages of the varieties of Orchid from the flowers. The arrows are thick and round for the top grade, and the flat and thin ones are for the middle grade. The flowers are large and colorful, resembling a wide funnel-shaped, and the petals are turned outward or spoon-shaped at the tip of the petals.

The flower color is generally vermilion, orange red, and apricot red. The flower shape is small, cylindrical, the tip of the petal is more erect, and the flower color is light red and orange.
