A quality prediction model for spray cut chrysanthemums in a solar greenhouse

Abstract: Based on chrysanthemum quality due to temperature and light differences as well as experiments with different spray cut chrysanthemum cultivars(Mengbai,Qinglu,Cuilian,Hanfen and Lv Fengwo) and planting dates(April,May,and June),a preliminary quality prediction model for solar greenhouse spray cut chrysanthemums with a physiological product of thermal effectiveness and PAR(photosynthetically active radiation) as the measurement scales was developed. The indexes including plant height,leaf number,leaf area of individual plant,stem diameter,flower diameter were observed. The model was then validated with independent data. Simulated results showed that based on a 1 ∶ 1 line,the coefficient of determination (R2) and percent relative prediction error (ERP),respectively,for plant height(0.99,7.2%),leaf number(0.99,6.9%),leaf area (0.94,10.2%),stem diameter (0.87,5.6%),and flower diameter (0.92,18.2%),agreed well with the observed data. This high precision model could supply a theoretical basis for optimizing:1) temperature and light management and 2) a decision support system for production of spray cut chrysanthemums in a solar greenhouse.[Ch,2 fig. 3 tab. 14 ref.]
