Sunscald on Schisandra chinensis fruit is a common physiological disorder that causes certain losses in production every year. With global climate warming, this disease tends to worsen year by year. 1. Disease symptoms Sunscald in Schisandra chinensis mainly affects the fruit. The sunscald sites often appear blistered, with sunken necrotic spots, lignification, hardened lesions, or necrotic spots in the flesh tissue. The surface of affected berries initially turns white (yellow or pink), then becomes black-yellow to brown. When sunscald is severe, sunken necrotic spots appear in the flesh tissue, localized flesh tissue becomes necrotic, and the affected areas are prone to infection by other fruit rot pathogens, causing fruit decay.

Causes of soft rot and nest rot in Gastrodia elata and prevention methods
Soft rot and nest rot in Gastrodia elata is one of the reasons for low and unstable yields in Gastrodia elata cultivation. In the small tubers, white tubers and arrow tubers affected by soft rot, the tuber skin turns yellow and withered, the central tissue decays, and a foul-smelling white milky fluid oozes from the cut surface of the tuber. In the rotting nests of Gastrodia elata and inside the tubers, the rhizomorphs of Armillaria mellea are luxuriant and dense. Gastrodia elata depends on Armillaria mellea for growth, so why does soft rot and nest rot occur, and why is the area beneath the tuber skin filled with Armillaria mellea mycelium? To explore this question, we should start with the nutritional ecology of Gastrodia elata. Gastrodia elata has no roots and no green leaves, its autotrophic organs are degenerated, and it relies on Armillaria mellea
