Southern blot suggested that the genome of malus xiaojinensis cheng et jiang has these genes Southern杂交结果表明：小金海棠基因组中存在该两家族基因。
Influences of nitrogen ratio and carbon sources on adventitious shoots regeneration of malus zumi leaves in vitro 氮源比例和不同碳源对珠美海棠离体叶片再生不定芽的影响
Studies on the pod activities in pearleaf crabapple malus zumi leaves damaged by plum spider mite tetranychus viennensis 暗条件下万寿菊根氯仿提取物对山楂叶螨酯酶的抑制作用
The most widespread species is malus hupehensis ( pamp . ) rehd . , whose distribution covers 17 provinces , municoplalities and autonomous regions 在所有种类中，分布最广的种是湖北海棠，达18个省、市和自治区。
In addition , m . toringoides has complex morphological variation and a series of variants were found between malus kansuensis and mains transitoria 该物种形态变异的类型复杂，具有一系列从陇东海棠到花叶海棠之间的变异类型。
The existing experimental results show that malus toringoides distributed widely in different area which has great altitude variation and complicated microhabitats 现有研究表明，变叶海棠分布面积较广，海拔高度差异较大，微生境极其复杂多样。
In this paper , we employ the gpsj1 distribution to construct the optimal bonus - malus system ( bms ) and bonus - malus system under the zero - utility theory 摘要本文利用gpsj1的性质，导出此分布类下的最优无赔款优待系统和零效用原理下的无赔款优待系统。
Ii ) some native spcies , eg . crateagus wilsonii , cerasus szechuanica , malus prati , toxicodendron verniciflua , are dominants and co - edificators in almost every woody communities 2 )华中山楂、四川樱桃、川滇海棠、漆树等乡土树种在几乎所有木本群落阶段(针叶纯林除外)都是优势种或共建种。
The altitude variation of the distribution of the different malus species in china reaches nearly 4000 meters , and they grow on various types of soil , even on desert , alkaline soil and on overhanging rocks and steep cliffs 在我国，苹果属植物不同种类分布的生境差异极大，生长的海拔范围差异近4000米，能生长在各种不同类型的土壤上，甚至沙漠、盐碱地到悬崖峭壁上都能生长。
5 out of approximately 120000 plaques , ten positive cdna clones were isolated from a fe - deficiency root cdna expression library of malus xiaojinensis by screening library for three times using tamre - bp cdna as a probe , then two representative clones were 5 " sequenced 5 、用小麦金属反应元件tamre - bpcdna作探针，筛选小金海棠缺铁根cdna表达文库，通过对约120000pfu的文库进行三轮筛选，共获得10个阳性克隆。
