本试验研究了卡拉布雷斯的生长发育，共进行了四年（1986-1989），每年使用五个品种和一系列的移植日期。通过每周取样和解剖监测作物生长情况，数据用于提供信息，以改进作物规划和预测。移栽至成熟时间与移栽期的关系可用平行二次曲线拟合。这些占76%的方差从移植到成熟的时间，可用于规划连续性时间表。然而，由于作物对天气的反应，拟合线的变化幅度很大，这表明在实践中很难实现连续性。所有品种的穗径对数与穗分化累积有效日度之间的逻辑斯蒂关系可解释穗径变异的96%，个别品种可解释穗径变异的97%。
SummaryExperiments studying calabrese growth and development were conducted in four years (1986-1989), using five cultivars and a range of transplanting dates each year. Crop growth was monitored by weekly sampling and dissection and the data are used to provide information to improve crop planning and prediction. The relationship between the time from transplanting to maturity and the date of transplanting was best described by fitting parallel quadratic curves for each cultivar. These accounted for 76% of the variance in the time from transplanting to maturity and could be used to plan continuity schedules. However, the magnitude of the variation about the fitted lines due to the crops’ responses to weather suggested that in practice continuity would be difficult to achieve. A logistic relationship for all cultivars between the logarithm of head diameter and accumulated effective day-degrees from head initiation accounted for 96% of the variation in head diameter and in individual cultivars up to 97% of...
