M.A. HAQUE AND
E.M. ENGLEEMAN
Abstract
Immature protophloem sieve elements
present in the embryo of phaseolus mungo mature about the time of germination . the sieve elements differentiate both acropetally and basipatally. There are numerous protophloem sieve tubes in the uppe hypocotyl. These are connected by anastomosis to four sieve tube, in the root . the protophloem sieve tubes are accompanied by hyperchromatic phloem parenchyma. Hyperchromaticity is the greatest near the differentiating end in the root vascular bundles in the cotyledon are amphicribral . thin deposis of callose are present in some sieve plates but absent in others.
