Mitochondria isolated from spinach (Spinacia oleracea) leaves oxidized glycine with a stoichiometry of CO2 evolution to O2 uptake of 2 : 1. In the absence of added substrate, the mitochondria exhibited an extremely low endogenous rate of O2 uptake.
نگرانی قابل توجهی در مورد بروز بیماری های ناشی از مصرف سبزی های حاوی نیترات و نیتریت زیاد مانند اسفناج وجود دارد. پژوهش حاضر به منظور بررسی تجمع نیترات و نیتریت در اندام هوایی (برگ و دمبرگ) 44 توده اسفناج (spinacia oleracea l.) بومی ایران که در شرایط مزرعه رشد یافته بودند، انجام گردید. طرح آماری بلوک های کامل تصادفی شامل 44 تیمار (هر ژنوتیپ یک تیمار) و سه تکرار بود. میزان نیترات و نیتریت به روش...
Radish (Raphanus sativus L. cv. Cherriette), lettuce (Lactuca sativa L. cv. Waldmann's Green), and spinach (Spinacea oleracea L. cv. Nordic IV) plants were grown under 660-nm red light-emitting diodes (LEDs) and were compared at equal photosynthetic photon flux (PPF) with either plants grown under cool-white fluorescent lamps (CWF) or red LEDs supplemented with 10% (30 micromoles m-2 s-1) blue ...
Diacylgalactosylglycerol synthesis was a prerequisite for the incorporation of [1-14C]-acetate into linoleate and alpha-linolenate of isolated spinach (Spinacia oleracea) chloroplasts. Oleate at position 1 of diacylgalactosylglycerol was desaturated to linoleate and alpha-linolenate both in the light and in the dark. Some desaturation of palmitate was also observed after prolonged incubations.
HROMOSOME 1 of Spinacia oleracea, the longest of the complement, con'tains the "alleles" X , X", and Y , that effect sex determination (ELLIS and JANICK 1960; SUTO and SUGIYAMA 1961; IIZUKA and JANICK 1962). The genotype X X is pistillate, X"X and X"X" are potentially monoecious (although X"Xm is more highly male), and X Y and X"Y are staminate. The standard chromosome 1 is heterobrachial with ...
Present investigations were carried out during 1998-2000 at Shivri farm of Uttar Pradesh Bhumi Sudhar Nigam, Lucknow, India, to study the effect of vermicompost application in reclaimed sodic soils on the productivity of potato (Solanum tuberosum), spinach (Spinacia oleracea) and turnip (Brassica campestris). The soil quality was monitored during the experiment followed by productivity. The tre...
Male plants of spinach (Spinacea oleracea L.) senesce following flowering. It has been suggested that nutrient drain by male flowers is insufficient to trigger senescence. The partitioning of radiolabelled photosynthate between vegetative and reproductive tissue was compared in male (staminate) versus female (pistillate) plants. After the start of flowering staminate plants senesce 3 weeks earl...
Two proteins which have carbonate dehydratase (carbonic anhydrase, EC 4.2.1.1) activity were shown to be in the chloroplasts and in the cytosol of leaves of Brassica chinensis, Spinacia oleracea, and in variegated leaves of Tradescantia albiflora and Hedera canariensis. The chloroplastic enzyme is smaller than the one in the cytosol, as it runs farther on gradient polyacrylamide gels. It was se...
