Citrus spp. (un-grafted), known as Citrus Ungrafted (غیر قلمی لیموں), represents traditional citrus plants grown from seed without grafting. These trees generally exhibit strong root systems that adapt well to local soil conditions, offering resilience and natural growth patterns. Ideal for expert growers interested in preservation of genetic diversity and rootstock selection, un-grafted citrus trees provide authentic fruit quality and require attentive cultivation practices to optimize yield and health.
