为研究不同贮藏方式对棕榈种子活力的影响,采用Q2技术,通过测定萌发启动时间(IMT)、萌发氧气消耗速率(OMR)、理论萌发时间(RGT)等的Q2值,研究比较了常温气藏(AS)、4℃低温贮藏(CS)和常温沙藏(SS)3种贮藏条件下棕榈种子的活力。结果表明,3种贮藏方式下种子的活力均有所降低,但CS处理与新鲜种子(FS)的Q2值差异不显著,该处理下的棕榈种子较SS和AS能保持较高的活力,其OMR较快,IMT和RGT均较短,是最佳的贮藏棕榈种子的方法。本研究结果为棕榈工厂化育苗及育苗规范的制定提供了理论依据和技术指导。  相似文献

[Objective] This study was to systematically investigate the cultivated characters of Nandina domestica and to lay a foundation for breeding, cultivating, as well as its application in landscape. [Method] Using N.domestica populations from 13 different areas of Hunan Province as tested samples, the cultivated characters of N.domestica in both the cultivated type and wild type were systematically studied through field experiment and comparative analysis. [Resul] The phenological features of N.domestica from different areas and germplasm resources were basically identical; the growth patterns of cultivated type and wild type were also basically identical, but the cultivated type grew faster than the wild type; both the two types grew quickly at young stage, and either the annual growth of new shoots or the growth pattern of leaves confirmed the fitting curve of the Logistic equation. [Conclusion] This research provided basis for the exploitation and utilization the germplasm resources of N.domestica.  相似文献

[目的]系统研究南天竹栽培性状,为该树种的育苗、栽培与园林应用奠定基础。[方法]以湖南省13个不同地区的南天竹种群为试样,采用田间试验和对比分析的方法,对栽培型与野生型南天竹的栽培性状进行了系统研究。[结果]南天竹各地理种质资源物候特征基本一致;栽培型和野生型生长规律基本一致,但栽培型的生长速度大于野生型;不管是栽培型或是野生型南天竹的高生长在幼龄期都比较迅速,其新梢的年生长、叶片生长规律都遵循Logistic方程的拟合曲线。[结论]该研究可为南天竹种质资源开发利用提供依据。  相似文献
