Walnut

A walnut is the edible seed kernel of a tree in the genus Juglans, enclosed in a hard shell and usually surrounded by a fleshy husk.

Juglans: Juglans is a genus of deciduous trees that includes walnuts and butternuts. Walnuts are the edible seeds produced by trees in this genus.
Walnut oil: Walnut oil is edible oil extracted from walnut kernels. It is used in dressings and other dishes where its nutty flavor is valued.
Pollination: Pollination is the transfer of pollen to a plant’s receptive female reproductive structure. Walnut flowers rely chiefly on wind to transfer pollen between trees.
Walnut production in China: Walnut production in China is the cultivation and harvesting of walnuts across Chinese growing regions. China is the world’s largest walnut-producing country.
English walnut: The English walnut is the widely cultivated walnut species Juglans regia. It supplies most commercially sold walnut kernels.
Omega-3 fatty acid: Omega-3 fatty acids are polyunsaturated fats with a carbon–carbon double bond three positions from the methyl end. Walnuts are a notable plant source of the omega-3 fatty acid alpha-linolenic acid.
Dichogamy: Dichogamy is the separation in time of male and female reproductive activity in a plant. Walnut pollen release and female flower receptivity often occur at different times.
Walnut production in California: Walnut production in California is the state’s commercial cultivation of walnuts, concentrated in the Central Valley. California is the leading walnut-producing region in the United States.
Black walnut: Black walnut is the North American tree species Juglans nigra, valued for its strongly flavored nuts and timber. Its thick shell and distinctive flavor contrast with commercial English walnuts.
Alpha-linolenic acid: Alpha-linolenic acid is an essential plant-derived omega-3 fatty acid. It is the main omega-3 fat in walnut kernels.
