      More Details Abstract Fulltext PDF

      The ontogeny and structure of stomata have been studied in the fruit wall ofBrassica oleracea var.botrytis Linn, andEruca sativa Mill. They are of mesogenous trilabrate type. Ontogeny resembles stomata of vegetative parts. Sometimes, the number of subsidiary cells gets increased due to cell division in spiral of three subsidiaries. Stomata are absent on inner epidermis of pericarp. In both the plants, contiguous and incompletely developed stcmata are also present.

      More Details Abstract Fulltext PDF

      The mature stony endocarp ofRauvolfia serpentina L. Benth. ex Kurz consists different types of monomorphic sclereids; brachysclereids, macrosclereids, fusiform sclereids and filiform sclereids. They vary from each other in cell wall thickness, shape and size. They develop from parenchymatous cells undergoing a series of changes in their shape nearly at the post fertilization till the maturity of the fruit.

      More Details Abstract Fulltext PDF

      Comparative morphological and anatomical investigations on the seed of two major pulsesCicer arietinum L. (Desi Chana) andCajanus cajan (L.) Millsp. var.bicolor DC. (Arhar)—vis-a-vis their common adulterant (Lathyrus sativus L. (Khesari Dal)), have yielded several features of value in pin-pointing adulteration in the market samples. Being basically similar in constitution, the seed coat in all the three taxons-comprises (i) a cuticle, (ii) an epidermis, (iii) a hypodermis, and (iv) a mesophyll. While the cuticle is ‘thick and wavy’ inCicer arietinum and ‘thin and smooth’ inCajanus cajan, it is notably ‘thick and dentate’ inLathyrus sativus. The macrosclereids constituting the epidermis and osteosclereids forming the hypodermis provide a set of contrasting features with regard to their shape, size, thickness and lumen/corrugation thereof.
