‘凤丹’在拉萨的引种适应性观测

Observation on Adaptability of‘Fengdan’(Paeonia ostii)in Lhasa

以2011和2014年引种的两批2年生的‘凤丹’苗为研究材料,于2017年观测其开花特性、心皮数、花粉散粉方式、柱头可授性、植株的茎粗、株高、叶片数、新枝长度、芽数等指标,研究结果表明:油用牡丹‘凤丹’能够在拉萨适应且长势一般,都已开始开花结实,但结实率不高,还存在种子不能早熟的现象。‘凤丹’作为油用牡丹在拉萨及其类似生存环境下能够完成整个生活史。

Two batches of two-year-old‘Fengdan’seedlings introduced in 2011 and 2014 were used as research materials.Observed in 2017 its flowering characteristics,carpel number,pollen loosening method,stigma receptivity,plant stem thickness,plant height,leaf number,new branch length,bud number and other indicators.The research results show that(Paeonia ostia)‘Fengdan’can adapt to Lhasa and grows normally,and it has begun to flower and bear fruit,but the seed setting rate is not high,and there is also a phenomenon that the seeds cannot mature early.As Paeonia ostii in Lhasa and its similar living environment,‘Fengdan’as an Paeonia ostii can complete the entire life history in Lhasa and its similar living environment.
