What you need to know about the base and scion of pistachio seedlings! Selection of rootstock is one of the most pistachio shell important issues that should be considered when constructing any pistachio orchard. Although all scion of pistachio cultivars can be grafted on all its species, but in Iran to increase pistachio seedlings from three species of pistachio scion called pistachio Domestic (P.vera) Chatlanqush (PK hinjuk) and pistachio (P.mutica) are used as a base. In most pistachio orchards in Iran, the domestic species P.vera has been used as a base. Its initial growth is high and it is well compatible with scion of different cultivars of pistachio, but it is sensitive to root-forming gland nematodes, gum and verticillium. Coriander root is known as one of the rootstocks resistant to pistachio root tuber and nematode rootstock as a rootstock resistant to drought and dehydration. In the US state of California, the success of pistachio cultivation depends on the selection and cultivation techniques of the rootstocks that ensure the expansion of the pistachio field in that country. So far, five wild pistachio species have been used in the California pistachio industry (P. integrrima), (P. atlantica), (P. terbinthus), and two other two-stemmed intercostal blood vessels (Atlica). ری Enterigma) is obtained.
