1.2.5. Physical characteristics, total soluble solids, acidity and vitamin C determinations Fruit, flesh and seed weight, flesh/seed ratio, fruit length and diameter were recorded independently in each of 25 fruit per replicate at the bisir and the rutab stage.
2.A homogeneous sample was prepared from these 25 fruits per replicate for measuring total soluble solids (TSS), acidity, vitamin C, total phenols and soluble tannins.
