“…To address the above question, we conducted experiments to clarify a) whether water deficit imposed on a soybean plant prior to flowering caused abortion of the basal flowers on the rachis, which are very likely to develop seed-bearing pods under favorable conditions, and b) whether the abortion, if occurred, was due to the impairment of stamen (pollen) or pistil (ovule) function (Kokubun et al, 2001;Kokubun, 2004). IX93-100 plants were grown for this experiment in controlled environment chambers (30/20ºC day/night temperature, 60 ± 10% relative humidity, 15-h photoperiod at 600 μmol m-2 s -1 PPFD on the plant canopy).…”
