Effects of seed size on seedling vigourin idigbo (Terminalia ivorensis)

The effects of seed size on seedling vigour of Terminalia ivorensis were investigated. Seeds were collected from plantations of the species located at the Forestry Research Institute of Nigeria, Ibadan, Oyo State , Ore Forest Reserve, Ondo State and Awi Forest Reserve in Cross River State of Nigeria...
