Effect of inhibitors on root growth of detached embryos supplied with sugars. A, Root length was measured on embryos that had been excised from dry grains and grown in liquid culture with MS medium for 6 d with 500 μm inhibitor or without inhibitor (water) and in the presence or absence (none) of 3% (w/v) sugar. Values are means ± se of measurements on the following numbers of seedlings (left to right for each sugar treatment). None: 10, 6, 4, 4; Glc: 14, 6, 4, 3, 4; Suc: 10, 6, 4, 8, 4; maltose: 14, 6, 3, 4, 4. B, Root lengths for whole seedlings, grown under the same conditions as embryos, in the absence of sugars and in the presence or absence (water) of 500 μm inhibitor. Values are means of measurements on the following numbers of seedlings (left to right): 8, 3, 2, 4, 2. Error bars represent se.
