Ears of uniculm wheat (Triticum aestivum L. cv. Gigas) grown in liquid medium for 11d absorbed more solution when the saccharose concentration was 2 % than when it was 10 %. When the ears were grown in 6 % saccharose solution, the rate of uptake from the solution was between that from the 2 and 10 % saccharose medium. Dry mass per grain increased with the saccharose concentration in the medium and the reduced uptake of solution did not decrease the moisture percentage of the grain. The culture of ears decreased pH of the solution with 2 % saccharose more than with 10 %. Addition of 0.5% chloramphenicol to the culture solution had no adverse effect on grain mass; it prevented contamination of the solution and maintained a higher pH

Keywords: absorption; chloramphenicol; pH
