在烟草生产中,既要重视产量,又要特别注意质量,而烟叶质量与产区的土壤性质、生长期的气温、光照、降水等气候条件关系特别密切。本文运用气候生态的观点探讨气候条件与烤烟生长的关系,试图分析云南烤烟大田生长期的有利和不利气候因素,为我省今后进一步提高烟叶品质提供依据。一、云南烤烟产区的气候条件云南地处低纬度高原,气候温和,光照充足,雨量适中,适合烤烟生长和优质烟叶生产。
In tobacco production, we must pay attention to production, but also pay special attention to quality, and leaf quality and the production area of the soil properties, growth temperature, light, precipitation and other climatic conditions are particularly close. This paper discusses the relationship between climatic conditions and the growth of flue-cured tobacco from the perspective of climatic ecology, trying to analyze the favorable and unfavorable climatic factors during the growing season of flue-cured tobacco in Yunnan Province, and providing the basis for further improving the quality of tobacco in our province. First, Yunnan flue-cured tobacco production areas of climate conditions Yunnan is located in the low latitude plateau, a mild climate, adequate sunshine, moderate rainfall, suitable for tobacco growth and high-quality tobacco production.

种子休眠性是影响大麦麦芽品质的一个重要参数。深度休眠的种子需经过长时间才能萌发,这将消耗大量的时间和贮藏成本;另一方面,不具有休眠性的种子可能导致穗发芽。脱落酸(ABA)是造成种子休眠的重要原因之一。深入了解ABA作用于种子的休眠分子机理对于长期贮存种子、科学破除休眠以及农业生产均有重要的意义。本研究以野生和栽培大麦为材料,筛选获得休眠差异性显著的材料。通过同源比对,获得大麦中ABA受体PYRL家
