Catalase, Peroxidase, and Polyphenoloxidase Activities during Rice Leaf Senescence.
The activities of catalase, peroxidase, and polyphenoloxidase were studied in attached and detached rice (Oryza sativa L. cv. Ratna) leaves. Catalase activity decreased while peroxidase andExpand
Catalase Activity in Leaves and Cotyledons During Plant Development and Senescence1)1) Part X of the series "Studies on Leaf Senescence". Supported in part by a Grant from the Council of Scientific
Catalase activity was studied as a function of the level of leaf insertion in eight monocotyledonous and eight dicotyledonous plants. Catalase activity was higher in the mature leaves than in theExpand
Nickel in plant growth and metabolism
SummaryThe relationship of nickel to plants in regard to absorption, translocation and accumulation and its estimation in plant material has been presented. Nickel is usually absorbed in the ionicExpand
Pyrophosphatase, Peroxidase and Polyphenoloxidase Activities during Leaf Development and Senescence.
Inorganic pyrophosphatase, peroxidase, and polyphenoloxidase activities were studied as the function of leaf insertion level in eight monocotyledonous and eight dicotyledonous species. AlkalineExpand
Nickel Nutrition of Plants: I. Effect of Nickel on some Oxidase Activities During Rice (Oryza sativa L.) Seed Germination
Summary Effect of different concentrations of nickel chloride (10 -6 M to 10 -1 M) on the germination rate and root-shoot length of rice ( Ozyza sativa L. cv. Ratna) seeds are studied. GerminationExpand
Inorganic pyrophosphatase activity during rice leaf senescence
The activities of the acid and alkaline inorganic pyrophosphatases (EC. 3.6.1.1) were determined in attached and detached senescing rice leaves. The acid inorganic pyrophosphatase had the pH optimumExpand
Effect of benzimidazole and nickel ions in the control of Oryza sativa leaf senescence by red and far-red light
Abstract Changes in the levels of chlorophyll and protein were determined in detached rice leaves floated on water, benzimidazole (mM) and nickel chloride (mM) under continuous dark, red (R) andExpand
Effect of benzimidazole and kinetin on the nicotinamide nucleotide content of senescing wheat leaves.
Assays of nicotinamide nucleotides were made on detached leaves of wheat, Triticum dicoccum var. Khapli, immediately after excision and at the end of a 16-h photoperiod and 8-h dark period at 1, 3,...
Regulation of senescence in detached rice leaves by light, benzimidazole and kinetin.
Abstract The senescence of excised leaves of Oryza sativa Var. BBS 873 was followed by measuring the net breakdown of chlorophyll and protein with respect to the time of detachment. Kinetin wasExpand
