Variations in the time course of flowering and in its intensity were recorded for regions in Israel along with variable climatic conditions. Such variations had an effect on pollen release into the air and on pollen counts. Two approaches for forecasting allergenic pollen dispersion were compared: (1) a survey of floral development and flowering intensity and (2) a survey of airborne pollen. There was a positive correlation between the survey of flowering and airborne pollen counts, although pollen was occasionally found after the flowering season. Further, it predicted fairly accurately the beginning of the flowering time of each species in each regio, the expected flowering duration, and intensity. Conducting a survey of flowering is a simple, easy and inexpensive operation. It is highly recommended for regions with variable climates.
针对以色列不同地区，记录了开花时间进程及其强度的变化情况，同时还记录了多变的气候条件。此类变化对花粉向空气中的释放以及花粉计数产生了影响。比较了两种预测致敏花粉扩散情况的方法：（1）花卉发育和开花强度调查；（2）空气中花粉调查。尽管在花期过后偶尔仍能发现花粉，但开花情况调查与空气中花粉计数之间存在正相关关系。此外，它相当准确地预测了每个地区每种植物的开花时间起始点、预期开花持续时间和强度。开展开花情况调查是一项简单、易行且成本低廉的操作。强烈推荐在气候多变的地区采用。
