Book Description
Greenhouse-grown, September-harvested Lilium longiflorum cv. 'Nellie white' bulbs were used to determine temperature requirements during 5 pre-bloom and 1 post-bloom phases of development each of 1 month's duration. Plantes were subjected to 3 air temperatures(24°day/ 18°C night, 18°/13° and 13°/10°) in combination with soil temperatures at 30°, 24°, and equal to or lower than ambient air temperature during each growth phase and evaluated by growth analysis at the termination of each phase. This study has substantiated that top growth needs high air temperature and daughter scale initiation and filling require high soil temperature. An air and soil temperature of 24°C was required for rapid flowering, leaf unfolding and stem elongation but at the expense of reserves in mother scales. Air temperature approaching 18°/13° during the month prior to anthesis favored maintenance of mother scales. Growth of daughter scales during the pre-bloom period was directly related to soil temperature rather than air temperature with 30° soil temperature being no better than 24°. Soil temperature had no effect on flower bud expansion after buds-visible stage, air temperature being the determining factor thereafter. Growth of the flower bud, leaf unfolding rate or stem elongation were of equal value in monitoring crop growth rate and status. Soil temperatures approaching 24°C. favored scale primordia initiation, regardless of air temperature. Daughter meristem diameter, as well as the rate of scale primordia initiation decreased progressively from daughter bulb appearance toward anthesis of the mother axis. High soil temperatures also reduced daughter bulb apex diameter during early growth phases. Since prevailing air and soil temperatures in the commercial lily growing sites are below those required for maximum growth and development of above- and below-ground organs during the pre-bloom period, it is concluded that air temperatures alone are adequate in monitoring field crop status and predicting ultimate yield potential during this period.
