This article needs a bit of a rewrite to cover animal dormancy, as even the introduction is of a botanical nature only. Fbriere 03:32, 25 Mar 2005 (UTC)
The development of communications have led to a wider cultivation of temperate fruits, cultivars being selected and grown in different environmental conditions. The demand of temperate-zone fruits is very intense in tropical countries but the production in these warm regions is limited by the lack of winter chilling (Subhadrabandhu, S. 1995). This situation has increased the risks derived from the incomplete breaking of dormancy, and encouraged studies concerning the chilling requirements of fruit cultivars for breaking dormancy. In cool regions the period of endodormancy is terminated rather soon but when there is no chilling, the intensity of endodormancy would not decrease, leading to an extreme case of prolonged dormancy. Saure M. C. (1985) in his review of dormancy, described the symptoms of prolonged dormancy in deciduous trees as the following: · Delayed, protracted, and very weak leafing · Formation of unbranched shoots that become increasingly shorter due to shorter internodes · Quickly declining growth vigor and early senescence of the trees · Delayed and protracted flowering season · Poor fruit development and irregular ripening
