ThesisItem Open Access Flower bud differentiation in clove, Eugenia caryophyllus (Sprengel) Bullock & Harrison(Faculty of Agriculture, Department of Horticulture, College of Agriculture, Vellayani, Trivandrum, 1989) Pauline Lina, Edwin; KAU; Vasanthakumar, KInvestigations on flower bud differentiation in clove were carried out at College of Agriculture, Vellayani from August, 1936 to December, 1987. Bearing clove trees (seven years old) at the Instructional Farm attached to the college were utilized for the study. The plant specimens were stored in FAA (Formalin-acetoalcohol) and then dehydrated through tertiary butyl alcohol - iso propyl alcohol series. The specimens were Infiltrated and embedded In paraffin wax (m.p. 58-60'C) and sectioned In a rotary microtone. The sections were then de-waxed, stained and examined for the anatomical features and photoalerogra- phed. The weather parameters and the nutritional factors recorded daring the period of study and those during sixteen fortnights prior to differentiation, were correlated with the data on flower bud differentiation. Significant positive correlation was obtained between the maximum temperature during the sixth to tenth fortnights before differentiation and the percentage of flower buds differentiated. Sunshine hours during ninth to twelfth fort night prior to differentiation showed a positive correlation with the percentage of flower bud differentiation.ThesisItem Open Access Influence of different levels of calcium and phosphorus on the growth, yield and composition of two high yielding varieties of rice, padma and jaya(Division of agricultural Chemistry, Agricultural College & Research institute Vellayani, Trivandrum, 1970) Sivan Nayar, P N; KAU; Koshi, M MThesisItem Open Access Studies on the lack of response of phosphatic fertilizers to rice in the laterite soils of Kerala(Division of agricultural Chemistry, Agricultural College & Research institute Vellayani, Trivandrum, 1970) Akbar, A; KAU; Subramoney, NThesisItem Open Access Inheritance studies on the F2 generation of intervarietal crosses in rice(Division of Agricultural Botany, Agricultural college & research institute , Vellayani Trivandrum, 1970) Abdurahiman, P V; KAU; Namboodiri, K M NThesisItem Open Access Studies on the intervarietal hybrids of Solanum melongena, L.(Division of Agricultural Botany, Agricultural college & research institute , Vellayani Trivandrum, 1969) Vijaya Gopal, P D; KAU; Sethumadavan, PThesisItem Open Access Cation exchange studies in Kerala soils(Division of agricultural Chemistry, Agricultural College & Research institute Vellayani, Trivandrum, 1969) Venugopal, V K; KAU; Joshy, M MThesisItem Open Access F2 studies on the manifestation of hybrid vigour and inheritance of quantitative characters in two inter varietal crosses in brinjal (Solanum melongena Linn.)(Division of Agricultural Botany, Agricultural college & research institute , Vellayani Trivandrum, 1968) Easwai Amma, C S; KAU; Sreenivasan, KThesisItem Open Access Studies on the formulation of selection index for yield in chillies (Capscicum annum, L)(Division of agricultural botany, Agricultural College & Research Institute Vellayani, Trivandrum, 1967) Sankara Narayana Pillai, R; KAU; Kumara Pillai, PThesisItem Open Access Studies on inter-varietal hybrids of rice (Oryza sative Linn.) with special reference to hybrid sterility and heterosis(Division of agricultural botany, Agricultural College & Research Institute Vellayani, Trivandrum, 1967) Narayanan Unnithan, K; KAU; Kumara Pillai, P
