Effect of Daminozide and NAA on Ca Uptake and Accumulation in ‘McIntosh’ Apple Seedlings1

Year: 1976

Type: article

Abstract: Leaves from succinic acid-2,2-dimethylhydrazide (daminozide)-treated seedlings of ‘McIntosh’ apple ( Malus domestica Borkh) accumulated significantly more 45 Ca than those from 1-napthaleneacetic acid (NAA)-treated seedlings. Stem sections from daminozide-treated seedlings accumulated significantly more 45 Ca than stems from control seedlings. Total 45 Ca content in daminozide-treated seedlings was significantly greater than in either controls or NAA-treated seedlings. The expected reduction in total shoot length by treatment with daminozide, NAA + daminozide and NAA was noted. The increases in 45 Ca content in all treatments appear to be due in part to the concentration effect of reduced shoot growth and in part to an effect of daminozide on rate of uptake.
