Causes of Gastrodia elata Trait Degradation and Control Methods
Degradation of Gastrodia elata traits often manifests as decreased yield of arrow gastrodia, with individuals becoming smaller and slender; a substantial reduction in the yield of rice gastrodia and white gastrodia, which turn ginger-yellow or light brown, with poor stress resistance, and the original yield and traits cannot be fully expressed. The causes are generally as follows: 1. Multiple generations of asexual reproduction. Generally after 5 to 6 generations of asexual reproduction...

How to prevent garlic clove degradation and leaf regrowth
When garlic grows to a certain stage, the scale buds begin to differentiate, the leaves degenerate, and the scale buds gradually form garlic cloves; the scales outside the degenerated scale buds form the outer skin of the garlic cloves. This is the general pattern of normal garlic growth. At the same time the garlic scape emerges, a ring of small garlic leaves grows around the scape, with 5-7 small leaves growing around the scape. These small leaves are a long new leaf that the outer skin of the new garlic clove sends out along the scape, while the growing point of the new garlic clove has not sprouted. This is called the garlic degenerated leaf regrowth phenomenon, sometimes called secondary
