Abstract

Studies made on different leaf characters in Malachra capitata showed that the leaf angle is negatively correlated with the length and width of leaves but positively correlated with the area of leaves. The leaf angles are differentiated into three forms according to the position of leaves on the stem.

Abstract

The present investigation was undertaken in one variety of Tomato, Best of All, to compare the cytogenetic effects of treatments of seeds of tomato with colchicine, diethyl sulphate and triethylamine and also to compare the morphological and physiological effects of these chemicals.

Lowest number of seeds germinated from diethyl sulphate treatment. Plants originating from colchicine, diethyl sulphate and triethylamine treatments showed many variant types. Interesting among these were those showing spotting on leaves originating from diethyl sulphate treatment, dwarf ones originating from colchicine and diethyl sulphate treatments and those with abnormal leaves originating from treatment with all the three chemicals.

Mitotic irregularities included clumped chromosomes and fragments at metaphase and bridges and fragments at anaphase while in meiosis clumped chromosomes, univalents, trivalents and quadrivalents were noted at metaphase I. Anaphase I irregularities included cells with fragments, bridges with or without fragments, lagging chromosomes and unequal separation of chromosomes. In metaphase II cells with aneuploid chromosome numbers and those with fragments were noticed while in anaphase II cells were found with fragments and unequal separation of chromosomes.

The importance of detecting interesting mutants in the M_a generation and the importance of finding translocations and inversions have been pointed out.

Abstract

The specific age at onset of menarche is a characteristic of an ethnic group and also determines the reproductive potential of a girl. Various factors, both genetic and non-genetic are known to have profound effect on the onset of menarche. Being distinct biological isolates due to frequent inter-tribal clashes, the tribal population groups of Arunachal Pradesh are characterized by their individual, cultural, religious and social lineage through which they have been able to maintain their separate entitites as distinct from other population groups and even from their fellow tribesmen.

Abstract

Apart from the nutritional excellence, the adoptability of chicken meat and meat products as an item of a diet, largely depends on its deliciousness and palatability, which in turn are very much interlinked with the qualities of tenderness, juiciness, flavour and texture.

Abstract

During the past decade considerable effort was evident in India towards improvement of indigenous feedsfuffs and rations for feeding poultry. Sathe and Bose, Desai et al, Ogra et al, Rao and coworkers among others have successfully employed a wide range of agricultural and industrial by-products as substitutes to the usual cereals and proteinic feeds in poultry rations. However, none of the earlier studies involved any systematic evaluation of the various feeds other than proximate analysis.
