云南松幼苗水分胁迫下的生理特性述评

云南松是云南特有的造林树种,其分布在云南中心的西南山地带,同时它在云南的社会和环境发展中与其他树种有着重要的地位,且带动着云南的经济发展.众多研究学者对云南松的苗木培育,自身所遗传下来的苗种以及丰收产品所运用的栽培技术和化感作用这些方面上做了许多研究,但是对苗木生长和综合质量上的影响所采取的措施都缺乏理论研究,当前国内对这方面幼苗的研究还没有报道连.所以,以后要对云南松在育苗的需要水的特性和生理指标以及采取的措施和综合的质量上的研究联系起来,为云南松的栽培技术和推广提供理论依据,还对云南松在育苗质量上有所提高,同时还对育苗抗性上有促进意义.

Effects of water Stress on seedling physiological Characteristics in Pinus

Pinus yunnanensis is the main tree species in Yunnan,which is the endemic species on the southwestern mountainous and Yunnan is the distribution center also,Pinus had an important position in Yunnan＇s economic, social and environmental sustainable development that can not be replaced with other species.Previous much research on genetic breeding of Pinus, seedling cultivation, high--yield cultivation techniques and attainment of Allelopathy, especially in seedling cultivation had more research data. However, these studies were restricted to the technical level and lack of theoretical research of breeding measures impact on seedling growth and integrated quality （physiological and morphological characters）. Up to now, the research of water physioLogy at Pinus seedlings had also not been reported at home and abroad. Therefore, combing Pinus seedling cultivation technology with comprehensive quality, water demand characteristics and physiological indicators linked to research, aimed at providing a theoretical basis for the promotion of Pinus and improvement of cultivation techniques, and had great significance on guiding breeding, improving seedling quality and breeding for resistance in future.
