控制低温能促使容器内生长的油橄榄(Olea europaea L)在一年内的任何时间开花。最适宜花序产生的控制条件,发生在暴露70—80天后,每日的正弦波温度型最低为-2℃,最高为15℃。虽是同样的温度,但是也要控制一个接一个的意外失败才能使花序形成。经常保持12.5℃的中等温度,也能有效地促使花形成,但是持续7℃的低温或持续15℃以上的高温就会导致花序形成的失败。“阿斯柯拉诺(Ascolano)”花序的生成对温度型的范围宽度低于“蒙扎尼罗(Manzanillo)”。在加利福尼亚的中心山谷,油橄榄的不规则生长习性,并不是由于冬季低温型变化的结果。七年间的冬季低温数据和随后的收获量证明与此无关。严寒甚或冬季温暖在那里都能着生足够的花。
Controlling the cold causes olea europaea L to bloom in the container at any time of the year. The optimum conditions for the production of inflorescence occurred at a daily minimum of -2 ° C and a maximum of 15 ° C after 70-80 days of exposure. Although the same temperature, but also to control one after another accidental failure to inflorescence formation. Regularly maintaining a moderate temperature of 12.5 ° C also effectively promotes flower formation, but a low temperature of 7 ° C or a sustained high temperature of 15 ° C or more results in failure of inflorescence formation. The “Ascolano” inflorescence produces a lower temperature range than the “Manzanillo”. In California’s central valley, the irregular growth habits of olive are not the result of changes in winter’s low temperature. Winter low temperature data for seven years and subsequent harvest proved to be irrelevant. Cold or even winter warm enough to produce enough flowers there.
