Effects of varieties and local rooting hormones on air layering of sweet orange (rus Sinensis (L.) Osbeck) in Ibadan.

Paper Details

Author(s)

Twelve sweet orange (Citus sinensis(L)Osbeck) varieties in the collection block of Citrus orchard at the National Horticultural Research Institute (NIHORT) Ibadan Nigeria were air layered using two growth hormones (Coconut milk and distilled water) to improve the success of the propagation technique. The aim was to produce seedlings of Sweet orange for ornamental. There was gall formation and root differentiation in all Sweet orange varieties. Etinan, Parson brown and Hamlin varieties were best in production of roots, while pineapple, Washington navel and Agege I had the least number of root. Bende variety was best in root diameter, while pineapple, Washington navel and Umudike were the least. Varietal differences and growth media did not have influence on root elongation of marcotted plant. Weaning of the seedlings after cutting from the mother plant showed that Valencia was significantly superior to all other varieties in seedling survival rate. The success recorded in this study revealed the potential of raising citrus through air-layered technique for ornamentals.

Abstract

Twelve sweet orange (Citus sinensis(L)Osbeck) varieties in the collection block of Citrus orchard at the National Horticultural Research Institute (NIHORT) Ibadan Nigeria were air layered using two growth hormones (Coconut milk and distilled water) to improve the success of the propagation technique. The aim was to produce seedlings of Sweet orange for ornamental. There was gall formation and root differentiation in all Sweet orange varieties. Etinan, Parson brown and Hamlin varieties were best in production of roots, while pineapple, Washington navel and Agege I had the least number of root. Bende variety was best in root diameter, while pineapple, Washington navel and Umudike were the least. Varietal differences and growth media did not have influence on root elongation of marcotted plant. Weaning of the seedlings after cutting from the mother plant showed that Valencia was significantly superior to all other varieties in seedling survival rate. The success recorded in this study revealed the potential of raising citrus through air-layered technique for ornamentals.
