In the development of agricultural science in the erstwhile Soviet Russia the academician T.D. Lysenko is regarded as a pillar. This great scientist of the bygone days was deeply concerned with the agricultural problems particularly associated with the then USSR and took up researches in that country to find practical solutions. Bringing forward the concept of growth and development in plants he could be able to establish clearly the specific environmental need in these physiological processes. Development of the practical procedure to shorten the time of flowering in winter type of cereal crops grown in that country by artificial exposure to cold otherwise termed in plant physiology as vernalization is a notable achievement of him. Among other versatile researches taken up by him in the area of agricultural science mention may be made to his study of genetics and plant breeding from a critical angle. In the present voluminous title authored by him the said scientist has brought to light the pertinence of his researchers and conclusions while citation of the related studies that had been undertaken by the contemporary and earlier scientists. 636 pp. N� de r�f. du vendeur 57362
