Abstract:
In this research, effects of high temperature on plant and effects of simulated shipping during an export process and recovery of bare-root young Phalaenopsis produced in tropical climate were monitored. Several kinds of non-destructive chlorophyll fluorescence devices were used to monitor photosystem II efficiency on Phalaenopsis intact leaves in high temperature exposure, low cost pre-shipping treatment, post-shipping performance, and re-transplanting recovery. Phalaenopsis pot plants were exposed to various temperatures at 28 °C, 35 °C and 47 °C. Photosynthetic quantum yield (ΔF/Fm') was monitored by mini-PAM®. A Fluorcam 700MF® CF imaging system was used to measure maximum photosynthetic yield (Fv/Fm) and ΔF/Fm' before and after temperature treatment, and then at 24 h of recovery. The Phalaenopsis leaves maintained 95% to 100% of Fv/Fm over a wide range of leaf temperatures (25- 42o C). LI-6400® photosynthesis system with LI-6400-40® fluorometer was used to monitor the effects of simulated export processes and the recovery of small bare-rooted Phalaenopsis (18 g FW) produced in uncontrolled tropical greenhouse in Thailand. Hardening did not affect Fv/Fm , but ΔF/Fm' responded to 7 days water loss (-23% FW) in hardening process. Simulated shipping for 30 days in the dark at 25°C and 80% RH reduced Fv/Fm but it was 87% recovered within 7 days and fully recovered 35 days after re-transplanting. ΔF/Fm' recovered 78 % when compared to control in the first 7 days and 83 % after 35 days of re-transplanting. Sensitivity of ΔF/Fm' in this experiment indicate that this parameter can be used as a detector of invisible damage from export process.
