Effects of watering following a drought period on nitrogen metabolism of cut Iris germanica flowers


, : Effects of watering following a drought period on nitrogen metabolism of cut Iris germanica flowers. Acta Horticulturae (41): 13-21

Flag iris flowers, cut when the terminal flower had reached the "open bud" stage, were given all or part of the following treatments: immersion of stems for 1 h in a 3H-leucine solution, followed by dry storage at 23 deg C + 40% RH for 24 h, followed by 2 h in a 14C-leucine solution, then immersion in water for 22 h at either 1 deg or 23 deg C. The period of water stress resulted in a fall in the protein content.

Feeding glucose to cut flowers of I. germanica slowed down the degradation of existing protein and promoted de novo protein synthesis. Cycloheximide treatment stopped flower growth almost completely, and slowed down protein and amino acid synthesi...
