Young apple trees growing in pots of soil were treated with N-15 labelled potassium nitrate or urea at different times of year. Over periods of several months whole trees were harvested and divided into their component tissues for total N and N-15 an

The absorption of nitrate by field bean plants at different times of development was investigated to determine the distribution and subsequent utilization of N up to the maturity of the beans. Nodulated plants were grown in sand culture and pulse-lab

Whole bean plants, ev. Cockfield, grown in pots crowded or well-spaced (50 or 10 plants m2, respectively) were treated with 14CO2 at the pod-fill stage (25 modes) and the radioactivity in each leaf was determined after 30 min. With spaced plants the

Young apple trees growing in pots of soil were treated in October with 15N-labelled urea on the foliage or with K15NO3 via the soil. Whole trees were sampled in the following February and May and the tissues extracted to determine the concentrations

Field bean (Vicia faba L.) cv. Maris Bead seeds were inoculated with Rhizobium Catalogue No. 1001, supplied by Rothamsted Experimental Station and grown in sand culture supplied with 15N-labelled nitrate at two concentrations. Plants were sampled at

When whole plants were exposed to 14CO2, almost the same amount of radioactivity was taken up initially by each leaf regardless of its position on the stem and of the presence of beans at that node. Thus, although developing beans are a powerful sink

Field bean (Vicia faba L.) cv. Maris Bead seeds were inoculated with Rhizobium Catalogue No. 1001, supplied by Rothamsted Experimental Station, and grown in sand culture supplied with a complete nutrient solution which included nitrate at either 1.5

The behaviour of ethylenediaminebis-(o-hydroxyphenylacetic acid) (EDHPA, Chel 138) and its ferric iron chelate (Fe-EDHPA) with activated charcoal and a cation-exchange resin is described and procedures are proposed for the recovery of this chelating

Solutions of amino acids are introduced rapidly into the xylem of short lengths of stem. At sampling the intact stem is first perfused with a salt solution to remove the amino acids still reversibly adsorbed by cation exchange. This fraction of the a
