How pistachio trees pistachio shell reproduce

Pistachio tree is propagated by grafting. Professional pistachio growers use a tree that combines two different textures, a base or a scion. The base is the lowest part of the pistachio tree and forms the root system.

Base resistance to soil diseases (such as verticillium wilt) is very important. The scion is located 20 to 40 cm above the main stem, the place where the growth and fruiting phase of the tree changes, and of course determines the characteristics of the fruit.

Both the base and the scion must be carefully selected, each of which may lead to poor yield. These scions are grafted on after the roots are planted in pistachio orchards.

In the United States, Kerman cultivar is the most popular female cultivar, which is mostly pollinated by male Randy cultivars. Pioneer Gold 1 and UCB-1 are hybrid hybrid bases that are very popular due to their Verticillium wilt resistance.
