Résumé partiel
On the basis of studies on introduction and growth of cultivars of Chinese jujube(Zizyphus jujuba)over years,a mumber of varieties suitable for desert area had been selected.The reproduction including tissue culture,cuttage(shoots and roots),grafting etc.,and growth techniques such as fertilization,density,flower and fruit preservation,disease and pest prevention,moisture retention.The results were as follows:1.Selection of cultivarsOn the basis of observations of 216 cultivars collected in a Chinese jujube variety garden set up by Wuwei Forestry Research Institute,70 of the cultivars,which had good characters,had been selected for further observation on their development,economic character,production and so forth.Of the 70,20 had been selected for desert area.Among the 20,the cultivars suit shelter-belt for farmland in desert area were(minly small-typed for dry fruist):Bachizao,Banzao,Shanxibenzao,Linzexiaozao,Shandongtangzao,Shuangbanz ao,(Minqinyuanzao)those for high yielding and dense-planting for desert area encompassed,Shanxilizao,Shupujidanzao ;those for eating and dry fruits referred to Ming shandazao,Kongfusucuizao,Shandonglizao,Junzao,Shandongdacui,Yuanlizao ;those for eating and fun contained:Longzao,Shanxilongzao,Chahuzao,Mopanzaoand those for processing involved:Jinzao.2.Studies on reproduction such as tissue cultureBased on the research into reproduction in vitro of Minqinyuanzao,an explant,which suits most reproduction in vitro—shoots for soilless culture in early spring,had been selected ;the starting substrate was H94+IBAO.1mg/L+NG15mg/L,a solid substrate,with addition of nutrient solution H65.The relay substrate was H66+NG20mg/L+IBAO.1mg/L.The relay culture opan was 30 days with an addition coefficient of 4.The substrate for rooting was H94+NG38mg/L+IABO.1mg/Lwith a rooting ratio of 90%.
