黑龙江省大兴安岭地区属高寒地区,有丰富的强酸性土壤资源,适合栽植矮丛越桔。为筛选适于当地栽培的品种,2005年我们从吉林农业大学引进美登、北春、北陆和北青4个越桔品种,建立2·7 hm2试验园,经3年栽培试验,只有美登品种在我区可安全越冬并丰产,栽后第3年每667 m2产量501·2 kg。(1)园地的选择土壤pH值是影响越桔栽培最重要的因子。适宜矮丛越桔生长的土壤pH值为4·0~5·5,最适值为4·3~4·8。土壤pH值过高易诱发越桔缺铁失绿,并导致钙、钠吸收过量;土壤pH值过低易导致重金属元素铁、锌、铜、锰等吸收过量而中毒。除土壤pH值外,选择栽培… 相似文献

《中国南方果树》2016,(5)
2014年由克莱姆森大学及美国农业部(USDA-ARS)公布了一些越桔属新品种,包括蓝莓新品种33个,具体包括北高丛蓝莓10个、南高丛蓝莓14个、兔眼蓝莓7个,还有2个未知类别的蓝莓新品种;除公布蓝莓新品种外,还公布了1个蔓越桔新品种。从公布的这些数据可以看出,近年来蓝莓的育种趋势多集中于早熟品种和晚熟品种,另外,鲜食品种多于加工品种,以及一些具有其他功能的蓝莓新品种也日益受到重视;蔓越桔品种的育种方向依然是开发大果、高产和抗病性好等优异性状的品种。结果可知,开发具有多种优异性状的南高丛品种是蓝莓育种的大趋势,其次是北高丛蓝莓和兔眼蓝莓,这也为开发出具有我国自主知识产权的蓝莓新品种指引一定的方向。本文主要介绍蓝莓、蔓越桔新品种及其特征。 相似文献

乌饭树嫁接高丛越桔技术研究 总被引：1，自引：0，他引：1
栽培越桔(蓝莓)Vaccinium spp.主要类群有高丛蓝莓(南高丛和北高丛)V.australe L.、矮丛越桔V.angustifolium Ait.和兔眼越桔V.ashei Reade。其中,高丛越桔商品性较好,栽培价值较高,栽培要求也较高;兔眼越桔适应性最强,栽培最容易。我国于20世纪80年代开始引种越桔,但由于品种资源、种苗繁育、土壤条件等多种因素影响,越桔尚未得到较好的发展。越桔繁殖多采用扦插方法,也有采用组织培养的,但不同品种对培养基的要求不同,且生根困难。据报道,与苹果、樱桃相比,高丛越桔在试管内生根较慢且生根率低[1]。为了探究高丛越桔新的良好繁育方法,… 相似文献

越桔对长白山区酸性土壤的适应性 总被引：15，自引：1，他引：14
在长白山区３种类型的酸性土壤上栽培越桔，研究结果表明，｀北空＇、｀美登＇、｀斯卫克＇在暗棕色森林土上生长结果较好，树体营养关系合理；在草甸沼泽土上３个种生长结果均较差，｀北空＇在水湿地潜育土上生长旺盛，但产量低，综合分析认为，矮丛越桔类型品种对我国长白山区酸性土壤条件的适应性较强，半高丛越桔则适应性差，针对长白山不同类型的土壤，以美登最为适宜暗棕色森林土栽培，斯卫克次之；水湿地潜育土可栽培美登品种 相似文献

Abstract Micropropagation techniques are important for clonal multiplication, germplasm improvement, and gene conservation of three commercially cultivated and medicinally important Vaccinium species: cranberries, blueberries, and lingonberries. The in vitro propagation of Vaccinium species using axillary bud proliferation and adventitious shoot regeneration has been investigated in a number of previous studies. The morphogenesis seems to be highly dependent on plant growth regulators and media used for culture, which is again genotype specific. This review presents the progress in-depth of various aspects of Vaccinium propagation in vitro for its commercial production. It also discusses the issues that still need to be addressed to utilize the full potential of plant tissue culture techniques in mass propagation of Vaccinium species. 相似文献

Abstract The F1 allotetraploid Vaccinium uliginosum♂ Vaccinium vitis-idaea♀ was found to be fertile and genetically compatible at different cross levels with taxonomically and geographically remote Vaccinioideae species. This genotype offers a wide application for artificial selection in V. vitis-idaea breeding by the remote hybridization method and for the production of genotypes with predetermined properties adapted to a wide range of growth conditions. 相似文献

ABSTRACT Jam from wild bilberries and from the blueberry culti vars ‘Bluecrop’ and ‘Berkeley’ were analyzed by means of sensory profiling and by instrumental measurement of anthocyanins, color, pH and soluble solids. The study shows that bilberry jam has more “bluish black color,” compared to a more “reddish-blue color” and “glossy” surface of the jam from cultivated blueberries. Bilberry jam was less “smooth” and higher in “viscosity” and “berry density” as well as less distinct in “flavor of flowers and fruits,” while the “blueberry flavor and odor” were more distinct in the bilberry jam than that made of highbush blueberries. Analysis of color by means of sensory hue and instrumental a Hunter lab corresponded well, as did saturation measured by the sensory method and chroma instrumentally measured. 相似文献

AIM: To explore the effect of Vaccinium vitis procyanidin on the growth of glioma cells. METHODS: Glioma C6 cells were cultured and divided into control and 10, 20 and 40 μg/L Vaccinium vitis procyanidin groups. The influence of Vaccinium vitis procyanidin on the growth of C6 cells was measured by MTT assay and the observation under inverted microscope. The apoptotic rate was detected by Annexin V/PI staining. The protein expression of Bcl-2 and Bax was determined by immunocytochemistry. The protein levels of Bcl-2, Bax and caspase-3 were also examined by Western blotting. RESULTS: The growth of C6 glioma cells was inhibited by Vaccinium vitis procyanidin at concentrations of 10, 20 and 40 μg/L. The growth was significantly inhibited in 40 μg/L Vaccinium vitis procyanidin group at 24 h and 48 h, and in 20 and 40 μg/L Vaccinium vitis procyanidin groups at 72 h (P<0.01). The density of the cells was decreased when the concentration of Vaccinium vitis procyanidin increased. The apoptotic rate was increased when the concentration of Vaccinium vitis procyanidin increased either. The expression of Bcl-2 was decreased and Bax was increased after 10, 20 and 40 μg/L Vaccinium vitis procyanidin treatments. The ratio of Bax/Bcl-2 was increased when the dose of Vaccinium vitis procyanidin increased (P<0.05 or P<0.01). The expression of Bcl-2 was decreased (P<0.01), and Bax and caspase-3 were increased after 10, 20 and 40 μg/L Vaccinium vitis procyanidin treatments. The ratio of Bax/Bcl-2 was increased when the dose of Vaccinium vitis procyanidin increased (P<0.01). CONCLUSION: Vaccinium vitis procyanidin inhibits the growth of glioma cells by down-regulating Bcl-2 protein and up-regulating Bax protein to activate caspase-3, thus inducing apoptosis. 相似文献
