本研究的目的是确定的物理化学变化，在高度着色品种的李子，可以作为一个指导，以评估最佳收获成熟度。研究了Gulfruby、Beauty、Shire和Rubyred四个品种果实的生长和成熟规律。呼吸速率和乙烯产生，皮肤颜色，硬度，可溶性固形物浓度和可滴定酸的变化记录在坑硬化，直到果实树成熟的时间间隔。为了评价乙烯在成熟过程中的作用，将丙烯施加于采收的果实。CV中的内部乙烯浓度。红宝石红也测量坑硬化后的时间间隔，无论是在收获的水果或水果附着在树上。与成熟相关的生理参数的变化的研究表明，没有一个适合于所有品种的李子收获成熟度的评估。然而，这种分析揭示了两种不同的模式，成熟行为的品种研究。Gulfruby和美丽表现出典型的更年期发展模式，而夏尔和Rubyred表现出抑制更年期表型。这种表型似乎是由于果实不能产生足够数量的乙烯来协调成熟。然而，用丙烯处理表明，显示抑制跃变型表型的果实仍应置于跃变型中。这种抑制跃变型的特征可以被纳入李育种计划，以产生具有改善的储存性能的新品种。(C)1997年Elsevier Science B.V.
The aim of this study was to determine the physicochemical changes in highly coloured cultivars of plums that could be used as a guide to assessing optimum harvest maturity. The patterns of fruit growth and maturation were investigated in the cultivars: Gulfruby, Beauty, Shire and Rubyred. Changes in the rates of respiration and ethylene production, skin colour, firmness, soluble solids concentration and titratable acidity were recorded at intervals from pit-hardening until the fruit were tree ripe. In order to evaluate the role of ethylene in the ripening process, propylene was applied to harvested fruit. Internal ethylene concentrations in the cv. Rubyred were also measured at intervals after pit-hardening either in harvested fruit or fruit attached to the tree. Studies of the changes in the physiological parameters associated with ripening showed that none were suitable for the assessment of harvest maturity in all cultivars of plums. However, this analysis revealed two distinct patterns of ripening behaviour in the cultivars studied. Gulfruby and Beauty showed a typical climacteric pattern of development, whilst Shire and Rubyred exhibited a suppressed-climacteric phenotype. This phenotype appears to result from an inability of the fruit to produce sufficient quantities of ethylene to co-ordinate ripening. However, treatment with propylene showed that fruit displaying the suppressed-climacteric phenotype should still be placed in the climacteric class. This suppressed-climacteric character could be incorporated into plum breeding programs to produce new varieties with improved storage properties. (C) 1997 Elsevier Science B.V.
