摘要: 文冠果(Xanthoceras sorbifolia Bunge)是一种很有开发价值的食用油料,也是我国北方生物能源适生树种的代表。它具有极强的抗热、抗寒能力,生命力极强,是固沙防风的好树种,因此具有极高的开发价值。是因为种源不足,在开发过程中受到了一定的影响,所以为了扩大种源,进一步完善文冠果的培养技术。该试验以文冠果幼嫩茎段为外植体材料,经过消毒后接种在不同组合激素水平的MS培养基上诱导小苗。结果表明:①嫩茎在MS+6-BA1.0+NAA0.5培养基上诱导率最高;②在不同配方的继代培养基中,MS+6-BA1.0+NAA0.5培养基的分化系数最高,且苗的长势最好;③在不同浓度的生长素中1/2MS+IBA0.5+NAA0.05培养基生根率最高,且生根时间最短,根系较发达,长势良好;④在移栽试验中,基质(草炭∶蛭石∶珍珠岩)配比为2∶1∶1的移栽苗生根时间短,生根率最高(达到97.2%),且成活率达到80.38%,生长情况良好。

Abstract: Wood of Shinyleaf Yellowhorn is a great development value of edible oil and the representative of bioenergy suitable tree species in north of China.It has a strong ability to heat and cold resistance, strong vitality,It is a good species of sand-fixation wind.With the development of high value.Because lack of provenance and influenced in the development process, In order to expand the provenance and further perfecting Wood of Shinyleaf Yellowhorn cultivation technology.Young stem segment of Wood of Shinyleaf Yellowhorn was used as explant materials in this test,Disinfected after vaccination in different combination hormone levels on the MS culture medium of the induced rootstocks.The result showed: ①Young stem segment had induced the highest rate in MS+6-BA1.0+NAA0.5 medium. ②MS+6-BA1.0+NAA0.5 medium of differentiation coefficient was the highest in different formula transgenerational medium,and growing conditions of seedlings was the best.③rooting rate of 1/2 MS+IBA0.5+NAA0.05 culture medium was the highest in different concentrations of auxin,and the rooting time is shortest,root system was developed,grew well.④In transplanting experiment,matrix (peat,vermiculite,perlite) ratio of 2∶1∶1 transplanting seedlings rooting time was short,to take root the highest rate (97.2%),the survival rate reached 80.38%and growth in good condition.
