Environmental influences on flowering in protected ornamentals. - HH1324TPC

Description
Improvements in lisiathus crop scheduling are required if UK growers are to maintain and increase market share. Scheduling is difficult because little is known of the physiological responses of the species. Investigations will identify the effects of temperatures imposed during the propagation phase on subsequent growth and flowering of plants grown on under "standard" greenhouse conditions, and will quantify the seperate and interactive effects of temperature, light integral, light quality and photoperiod on flower initiation and development during the production phase, and relate these to quality aspects. A predictive, scheduling model relating the effects of environment to growth and floweing will be developed and validated under semi-commercail growing condtions. The effects on subsequent post-harvest longevity of water stress during the later phases of growth and of anti-ethylene pulsing treaments will be investigated.
Objective
Investigations will identify the effects of temperatures imposed during the propagation phase on subsequent growth and flowering of plants grown on under 'standard' greenhouse conditions, and will quantify the separate and interactive effects of temperature, light integral, light quality and photoperiod on flower initiation and development during the production phase, and relate these to quality aspects of Lisianthus. A predictive, scheduling model relating the effects of environment to growth and flowering will be developed and validated under semi-commercial growing conditions. The effects on subsequent post-harvest longevity of water stress during the later phases of growth and of anti-ethylene pulsing treatments will be investigated.
