Flower disease and its etiology

Flower disease:

1. The base of the tongue petal of the flower turns red.

Etiology: hypothermia injury.

two。 Flower tongue petals turn red or abnormally red, prematurely withered.

Cause: the flower has been pollinated or the flower has fallen off.

3. The outer edge of the tongue petal of the flower changed color and dried up, and some of the flowers were deformed.

Cause: flowers are exposed to bright light for too long.

4. The flowers wither before maturity and the ovary turns yellow or pink.

Cause: ethylene pollution.

5. The calyx first withered and changed color, and the petal veins became thinner obviously.

Cause: ethylene pollution.

6. Flowers are occasionally deformed.

Etiology: drug damage during flower bud differentiation, too large temperature difference or too much dosage of "budding hormone".

7. The flowers that bloom every time are equally deformed.

Etiology: it may be genetic. If the deformity is beautiful, then "scarcity is precious". (Xue Congxian)
