Factors Affecting Root Formation of Phaseolus Vulgaris.
The successful rootingof leafy cuttings inivolves three physiologieally distinct processes: initiation of root primordia; development of true roots from these initials; and mainitenance of the cutting as ani excised organ during the rooting. The first of these, where it does niot take place sponitanieously, cani be brought about in many plants by treatment with auxini. The second (outgrow^th of...
متن کاملFactors Affecting Cotyledonal Cracking during the Germination of Beans (Phaseolus Vulgaris).
Wlhile studying cotyledonal abnormality an unusual type of injury was observed in snap beans which had been carefully hand-picked and handshelled. The injury consisted of one or more transverse breaks which extended partially or completely across the cotyledon, severing the vascular elements, figure 1. Not only was the movement of materials into the seedling impeded by the breaks but the cotyle...
متن کاملGlycosidases of Phaseolus vulgaris
The enzymes, cr-galactosidase, P-galactosidase, a-mannosidase, P-glucosidase, and p-acetylglucosaminidase, have been purified from the germinating seeds of Phaseolus vulgaris. All five enzymes have been simultaneously isolated in a highly active form. The pH optimum, K,,,, and energy of activation of each glycosidase for the reaction of hydrolysis of the appropriate P-nitrophenyl glycoside have...
متن کاملHeat-labile growth-inhibiting factors in beans (Phaseolus vulgaris).
A comparative study in vitro was made of enzyme-inhibiting and hemagg1utinin activities, and the effect on rat growth of 5 varieties of kidney beans (Phaseolus vulgaris). Extracts of 2 bean samp1es were active in agg1utinatingrabbit b100d cells and toxic when .fed to growing rats. Diets prepared with these seeds supp1emented with methionine caused weight 10ss and death when fed to rats a10ne or...
متن کاملOligosaccharide Specificities of Phaseolus vulgaris
The structural determinants required for interaction of oligosaccharides with leukoagglutinating phytohemagglutinin (L-PHA) and erythroagglutinating phytohemagglutinin (E-PHA) from Phaseolus vulgaris have been studied by immobilized lectin affinity chromatography. Homogeneous oligosaccharides of known structure, purified following release from Asn with Nglycanase and reduction with NaBH4, were ...
