摘要

摘要建立了在AbaraÂn (Murcia)栽培的13个杏品种(Prunus armeniaca L.)开花所需的冷单位(CU)和热单位(HU)。根据花蕾干重的增加来确定休眠期的结束。在208℃下对花蕾施加压力后测量干重的测试结果表明，在检测重新激活阶段的开始方面，比没有施加压力的测试更精确。

COLD AND HEAT REQUIREMENTS OF THE APRICOT TREE (PRUNUS ARMENIACA L.)

SummaryThe cold units (CU) and heat units (HU) required for the flowering of 13 apricot cultivars (Prunus armeniaca L.) cultivated in AbaraÂn (Murcia) have been established. The end of the dormancy period was determined on the basis of the dry-weight increase of the flower buds. The tests in which the dry weight was measured after forcing the flower buds at 208C turned out to be more precise in detecting the beginning of the reactivation phase than those in which they were not forced.

期刊介绍： The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
