Causes of Gastrodia elata trait degeneration and control methods
Degeneration of Gastrodia elata traits usually manifests as a decline in the yield of arrow gastrodia, with the individuals becoming smaller and slender; the yields of rice gastrodia and white gastrodia drop substantially, the tubers turn ginger-yellow or light brown, stress resistance is poor, and the original yield and traits cannot be fully expressed. The causes are generally as follows: 1. Multiple generations of asexual propagation. Degeneration generally begins to appear after 5 to 6 generations of asexual propagation, but the speed of degeneration differs when cultivated on different soils; degeneration is slower when cultivated on granite soil, followed by yellow-brown earth sandy soil parent material, and the acidic soil formed by the weathering of shale or limestone.

What is Gastrodia elata trait degeneration? Trait degeneration in Gastrodia elata typically manifests as a decline in the yield of arrow tubers, which become smaller and slender; a substantial reduction in the yield of rice tubers and white tubers, which turn ginger-yellow or light brown, with poor stress resistance, so that the original yield and traits cannot be fully expressed.
