Root morphological characteristics in relation to growth of four tropical fruit seedlings

Root morphological characteristics and their relationships with growth habits of four tropical fruit seedlings, namely mangosteen (Garcinia mangostana L.), rambutan (Nephelium lappaceum L.), cempedak (Artocarpus champeden L.) and durian (Durio zibethinus Murr.), were studied. Seeds of selected fruit...
