摘要：研究了Montmorency cherry （Prunus cerasus L.）果实和树干在果实发育的不同阶段的日扩张和收缩。试验在频繁灌溉和土壤干燥循环条件下进行。处于中期发育阶段的果实通常在上午和下午早些时候收缩，然后从下午晚些时候开始扩大，一直持续到晚上。果实在发育的中期通常比茎缩得多。收缩的开始时间、收缩量和收缩持续时间随果实发育阶段、土壤水分有效性、天气和树木内部水分胁迫程度而变化。土壤含水量较高时，日收缩量、收缩时间和收缩结束与影响蒸腾的条件有关。在发育早期（第一阶段），果实通常在短时间内直径增加，白天不明显缩小，除非在严重的内部水分胁迫下。随着水果的临近……
SummaryDiurnal expansion and contraction of fruits and tree stems of Montmorency cherry (Prunus cerasus L.) were studied during various stages of fruit development. Experiments were performed under conditions of frequent irrigation as well as during soil-drying cycles. Fruits in a mid stage of development often shrank during the morning and early afternoon and expanded, beginning in late afternoon and continuing into the night. Fruits in mid stages of development usually shrank more than stems. The time of beginning, amount, and duration of shrinkage varied with the stage of fruit development, soil moisture availability, weather, and degree of internal water stress in the tree. When soil moisture contents were high the amount, time, and ending of daily shrinkage were correlated with conditions affecting transpiration. During early development (stage I) fruits usually increased in diameter in spurts and did not shrink appreciably during the day, except under severe internal water stress. As fruits approach...
