Gnomoniopsis castaneae (synonym Gnomoniopsis smithogilvyi) is a fungus of the order Diaporthales [2] that is the most important cause of brown chestnut rot, [3] an emerging disease [4] that damages the fruit of chestnuts. It also causes cankers and necrosis on leaves and on chestnut galls caused by the gall wasp, Dryocosmus kuriphilus. [5]
Browning of the chestnut burs at the blossom end may be a first sign in August. At harvest time, blackening of pointed end of the chestnut shell and kernel indicates infection. The extent of blackening can vary. It can range from a barely visible black tip of the kernel to the whole nut being black.
Inocarpus fagifer, commonly known as the Tahitian chestnut or Polynesian chestnut, [1] is a species of flowering plant in the subfamily Faboideae of the legume family, Fabaceae. The tree has a wide range in the tropics of the south-west Pacific and south-east Asian regions, and a history of traditional use by the peoples of Polynesia and ...
Preventing the browning from occurring is essentially an effort to slow down the enzymatic reaction of the fruit, Keathley says. Thus, “finding a method to block the enzyme from working properly ...
The sweet chestnut is naturally self incompatible, meaning that the plant cannot pollinate itself, making cross-pollination necessary. [5] Some cultivars only produce one large seed per cupule, while others produce up to three seeds. [5] The nut itself is composed of two skins: an external, shiny brown part, and an internal skin adhering to the ...
Botanically, a nut is a fruit with a woody pericarp developing from a syncarpous gynoecium.True nuts include, for example, chestnut, hazelnut and filbert.Culinarily, the term 'nut' is used much more widely, and includes examples of drupes (such as pecans and almonds) or seeds (such as pine nuts and peanuts).

Browning Fuji apple - 32 minutes in 16 seconds (video). Browning is the process of food turning brown due to the chemical reactions that take place within. The process of browning is one of the chemical reactions that take place in food chemistry and represents an interesting research topic regarding health, nutrition, and food technology.
