SOME QUANTITATIVE OBSERVATIONS ON PODS AND SEEDS OF VACHELLIA NILOTICA (L.) P.J. HURTER & MABB.
The pods and seeds collected from two mature trees of Vachellia nilotica (L.) P.J. Hurter & Mabb. from Karachi were studied for their quantitative characteristics such as their sizes, variation in their weights, inter-seed distances, pericarp and seed yields per pod, brood size and mean single seed weight per pod, pattern of within-pod seed size distribution, mother tree – and pod-related variation of individual seed weight, seed packaging cost and seed number – seed size trade off. The results have been discussed in the context of available ecological literature.
