Abstract
The seeds, seed covers and leaves, taken after 17, 27, 37, and 47 days after tagging of flowers of soybean, were analysed quantitatively for their contents of different phosphorus fractions. Total phosphorus content increased in seed cover and leaves, there was a gradual decrease during ripening. All the phosphorus fractions i.e. acid soluble—P, lipid—P, nucleic acid—P, and protein—P were found to increase with maturity in seeds whereas in case of seed covers the content of acid soluble—P, nucleic acid—P and protein—P decreased but a marked increase was observed in lipid—P. In leaves during ripening, all the phosphorus fractions decreased except protein—P which was found to be almost constant. In lipid—P an increase was observed during later stages of maturity.
Abstract
Byly prováděny analýsy na obsah fosforu v několika základních frakcích v semenech, osemení a v listech odebraných 17, 27, 37 a 47 dnů po odkvětu. Celkový obsah fosforu v semenech se během zrání zvyšoval, zatím co v osemení a listech se postupně snižoval. Ve všech frakeích, tj. v kyselinorozpustné frakei, lipidické frakei, frakei fosforu nukleových kyselin a ve frakei fosforu proteinů se v semenech během zrání obsah fosforu zvyšoval. V osemení se obsah fosforu snižoval ve frakeích fosforu rozpustného v kyseliních, fosforu nukleových kyselin a proteinů, zatím co výrazné zvyšování obsahu fosforu bylo pozorováno ve frakei lipidní. V listech se obsah fosforu postupně snižoval ve všech frakeích vyjma frakce fosforu proteinů, kde obsah fosforu zůstával na téměř stejné úrovni. Ve frakei fosforu lipidů bylo pozorováno zvýšení obsahu fosforu v pozdějších fázích zrání.
