Summary The sensitivity to temperature of the number of flowers per plant including flower buds (NFPP), flower size, position and colour was investigated in cut chrysanthemum (Chrysanthemum morifolium cv. ‘Reagan Improved’). Plants were grown either in a glasshouse at constant 24 h mean temperatures throughout cultivation (17°C or 21°C), or in growth chambers at 32 different temperature combinations (from 15°C to 24°C). The latter temperature combinations were applied by dividing the… 
Variation Between Cut Chrysanthemum Cultivars in Response to Suboptimal Temperature
To breed for more energy-efficient cut chrysanthemum cultivars it is important to know the variation of the temperature response existing in modern cultivars, which shows an optimum response to temperature, with the optimum around 24 °C.
The influence of temperature on growth and development of chrysanthemum cultivars
The effects of temperature, especially in the sub-optimal temperature range, on growth and development of chrysanthemum are reviewed with special emphasis on cultivar differences, especially on leaf unfolding rate and time to flowering.
Influence of temperature and ethephon spraying on the flowering of late July flowering-type small-flowered chrysanthemum (Chrysanthemum morifolium Ramat.) cultivars.
During the development of early-August harvest by spraying ethephon, ‘Michinoku’ turned out to be suitable for early- August harvest because of the small fluctuations of anthesis.
Physiological responses of Chrysanthemum x morifolium to low night temperatures
A greenhouse study was performed in the autumn of 2006 and replicated in the winter of 2007 to study the effect of low night temperature (LNT) on plant growth responses in vegetative Chrysanthemum x
To assess the strength and direction of a relationship between temperature (day, night, daily), light ( PAR) or light (PAR) and biomor- phological features, correlation coefficients were calculated and the temperature exerted a significantly positive effect on the quantity of fresh mass of chrysanthemum, the increments of the main shoot and the relative chlorophyll content in leaves.
High-Temperature Tolerance of Flowers
High-temperature-tolerant cultivars are identified or selected in floricultural and pomological (fruit) crops, and relationships between flower and heat in these various aspects are illustrated.
Genotypic Variation in the Response to Suboptimal Temperature at Different Plant Densities in Cut Chrysanthemum
The combined effect of temperature and plant density on growth and development of four cut chrysanthemum cultivars was investigated, and it was concluded that there are possibilities for breeding for suboptimal temperature-tolerant cultivars.
Changes of nutrient concentration in chrysanthemum leaves under influence of solar radiation
To find the relationship between nutrient concentration in plant tissue and radiation, data were analysed using simple linear regression models and found radiation had an effect on nutrient concentrations in chrysanthemum leaves.
Possibilities for soilless cultivation in cut chrysanthemum: Effect of irrigation frequencies and spacing schedules
Three levels of irrigation frequencies, provided by root misting, combined with three plant densities and two spacing treatments were tested to evaluate the optimum conditions during the first crop
Modelling external quality of cut chrysanthemum: achievements and limitations
This paper provides an overview of the achievements and limitations of modelling external quality of cut chrysanthemum, and develops a photosynthesis-driven growth model, for the prediction of dry mass production in year-round cut ch Chrysanthemums.


Development rate during four phases of chrysanthemum growth as determined by preceding and prevailing temperatures
Time required to complete four developmental phases in chrysanthemum 'Bright Golden Anne' (Dendranthema grand flora Tzvelev.) was determined under greenhouse conditions at constant temperature
Temperature Regime at Various Stages of Production Influences Growth and Flowering of Dendranthema × grandiflorum
For chrysanthemum [Dendranthema × grandiflorum (Ramat.) Kitamura], the hypothesis that a 12-hr 5C or 13C dark treatment could be used in conjunction with a 12-hr 27, 21, 17, or 13C light treatment
Effect of assimilate availability on flower characteristics and plant height of cut chrysanthemum: an integrated study
It is concluded that within a wide range of growth conditions chrysanthemum invests additional assimilates, diverted to the generative organs, in increasing NoF rather than in increasing flower size.
Temperature and photosynthetic photon flux influence chrysanthemum shoot development and flower initiation under short-day conditions
The effects of photosynthetic photon flux (PPF), day temperature (DT) and night temperature (NT) on leaf number, leaf unfolding rate and shoot length were determined for chrysanthemum grown under short day (SD) conditions.
