在九成宫基地，定位观察了三株杂交沙棘的新梢生长、叶数、叶重、结果数、落果率、果重等多个参数，研究了在严重水分亏缺胁迫下，沙棘随季节变化这些参数的相关胁变性。结果看到，干旱加重，出现了茎、叶、果的部分脱落，又以新梢脱落最重。新梢脱落的规律是由枝条下部开始，逐渐向上部发展，具有生理脱落的位移应答反应。杂交沙棘对干旱胁迫较敏感，在种植管理中注重在于早年份和干旱季节适时灌溉，减轻干旱胁迫引起的枯梢落叶和落果，是增产的必要和重要措施。

Multiple parameters, like the new shoot growth, amount and weight of leaves, berry numbers, fruit dropping rate, and the weight of berries have been studied in Jiuchenggong seabuckthorn base. The seabuckthorn strains with seasonal changes have been researched under the condition of serious water deficit stress. The results shown that the falling of stems, leaves and fruits are emergence with the drought aggravation, specially for the new shoots. The law of new shoots falling is beginning from lower branches, and up to top with the response of physiological off. The hybrid seabuckthorn is sensitive to drought stress, so the irrigation should be paid attention in dry year and drought season in planting management, alleviating drought stress caused by the falling of leaves and fruit is the important measure for sebuckthorn fruit production.
