Inhibition of phosphorus and water passage across intact roots by polyethylene glycol and phenylmercuric acetate.
Application of polyethylene glycol or phenylmercuric acetate to intact bean (Phaseolus vulgaris L., cv. Red Wade) roots inhibited passage of phosphorus across the roots to the xylem. The same results occurred for foliar application of phenylmercuric acetate when time was allowed for absorption and distribution of the chemical in the plant. For both chemicals the inhibition of phosphorus was pro...
متن کاملEffects of Foliar Selenite on the Nutrient Components of Turnip (Brassica rapa var. rapa Linn.)
We administered foliar applications of 50, 100, and 200 mg L-1 selenium (Se, selenite) on turnip (Brassica rapa var. rapa Linn.) and detected the changes in the main nutrient components in fleshy roots. Results showed that the foliar application of Se (IV) significantly increased the Se content in turnip, and Se (IV) positively affected the uptake of several mineral elements, including magnesiu...
متن کاملAutoradiography as an Aid in Determining the Gross Absorption and Utilization of Foliar Applied Nutrients.
Favorable growth responses have recently been obtained with some phosphorus compounds applied as foliar sprays to vegetable crops, the objective being to supplement the usual supply of phosphorus absorbed by the roots (3). Preliminary studies utilizing a 25 millimolar solution of phosphoric acid enriched with small quantities of radioactive phosphorus indicated that the nutrient was absorbed by...
متن کاملEffect of application methods of phosphate and zinc sulfate fertilizers on water use efficiency and qualitative characteristics of corn under water deficit stress
To study the effects of phosphate and zinc sulfate fertilizers application methods on water use efficiency and qualitative characteristics of corn underwater stress, an experiment was conducted in split plot factorial arrangement on randomized complete block design with three replications at research farm of the Bu Ali Sina University in 2014. Three levels of irrigation after 60, 90, and 120 mm...
متن کاملFOLIAR FEEDING Another Successful Way of Feeding Plants
Plant nutritionist have traditionally considered the obvious way to feed plants is through the soil, where plant roots are meant to uptake water and nutrients, but in recent years foliar feeding has been developed to supply plants with their nutritional needs. The development of pressurised irrigation equipment such as drip irrigation has promoted the need for water-soluble fertilisers, as clea...
