Effects 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 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 کاملOdor-active constituents in fresh pineapple (Ananas comosus [L.] Merr.) by quantitative and sensory evaluation.
By application of aroma extract dilution analysis (AEDA) to an aroma distillate prepared from fresh pineapple using solvent-assisted flavor evaporation (SAFE), 29 odor-active compounds were detected in the flavor dilution (FD) factor range of 2 to 4,096. Quantitative measurements performed by stable isotope dilution assays (SIDA) and a calculation of odor activity values (OAVs) of 12 selected o...
متن کاملEffects 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...
