Potted greenhouse-forced `Nellie White' Easter lilies (Lilium longiflorum Thunb.) were irrigated from emergence with water at 2, 5, 8, 11, or 15 °C either onto the shoot apex (overhead) or onto the substrate for a 0, 2-, 4-, 6-, 8-, 10-, or 12-week period. Control treatment was at 18 °C, either overhead or on substrate. When irrigation water was applied overhead for the entire period between emergence and flowering (12 weeks), plant height increased linearly with the temperature of irrigation water (1.75 cm/°C). As the period of application with cold water increased from 0 to 12 weeks, plant height decreased both in a linear and a quadratic manner. Forcing time was negatively correlated with height with the shortest plants delayed by 3 to 6 days. Water temperature did not affect bud abortion or the number of yellow leaves. Irrigation water temperature had no effect on plant parameters when applied directly on the substrate.

Leaf disks of Rhododendron cv. `English Roseum' were vacuum infiltrated with buffered solutions of L- or D-phenylalanine. Controls were infiltrated with buffer. Following a 24 hour period under lights (23°C, 16 hr light: 8 hr dark), the disks were cold shocked at 0°C for one hour, then held under the same light regime for three days. Disks were then subjected to a series of cold treatments, thawed, and analyzed for damage visually and by phenolic leakage. Disks infiltrated with D-phenylalanine consistently showed greater damage at warmer temperatures than did disks infiltrated with the L isomer. We believe the inhibitory action of D-phenylalanine upon phenylalanine ammonia-lyase is responsible for this decrease in cold hardiness.
