Effects of Nitrogen on Chlorophyll, Acidity, Ascorbic Acid, and Carbohydrate Fractions of Ananas comosus (L.) Merr.
Well-authenticated information on pineapple plant response to niitrogen constitutes a valuable criterion in commercial fertilizer practices because the amounts and time of their application are determined by the physical appearance of the plants, designated as plant status, as well as by chemical analyses of their tissues. Besides nutrition, physical factors such as light, temperature, and mois...
متن کاملChlorophyll and Protein Interrelationships in Ananas comosus (L.) Merr.
Studies on a quantitative separation and analysis of chloroplastic matter by different investigators have revealed that chlorophyll is held by chemical forces on proteinaceous matter. This matter, named phyllochlorin by MESTRE (17), chloroplastin by STOLL (37), photosynthin by FRENCH (8), and chloroglobin by RABINOWITCH (21), is presumably identical with the substance composing the stroma of ch...
متن کاملEffects of Different Amounts of Potassium on Growth and Ash Constituents of Ananas Comosus (l.) Merr.
The data reported in this paper were obtained from plants grown in nutrient solutions supplied with high or low amounts of potassium, namely 205 or 4 mg. per liter but with equal amounts of either nitrateor ammonium-nitrogen. Tops or crowns (vegetative organs produced at the apex of fruits) of uniform size from a single clone were placed in tap water for one month until they had produced about ...
متن کاملEffects of Potassium on Chlorophyll, Acidity, Ascorbic Acid, and Carbohydrates of Ananas Comosus (l.) Merr.
A study concerned with the effects of iron on chlorophyll, acidity, ascorbic acid, and carbohydrate fractions of Ananas comosus was reported in a previous publication (35). Also, the effects of different amounts of potassium on growth and ash constituents of the same plants were reported in a former paper of this series (36). This study is concerned with the effects of potassium on chlorophyll,...
متن کاملMANGANESE INTERFERENCE IN THE ABSORPTION AND TRANSLOCATION OF RADIOACTIVE IRON (Fe) IN ANANAS COMOSUS (L.) MERR.
The interference of manganese with the availability of iron to pineapple plants has been explained by JOHNSON (7) and KELLEY (9, 10) as due to the oxidation of the latter by the former in soil and leaf tissues. Additional studies by SIDERIS, YOUNG and KRAUSS (14) and SIDERIs and YOUNG (17, 20) revealed that iron may be made unavailable in ample amounts to the leaf tissues after its precipitatio...
