Subspecies characteristics in filial generation of cross between indica and japonica under different environments 不同生态条件下籼粳稻杂交后代亚种特性的比较研究
Relationship between chloride tolerance and polyamine accumulation in glycine max , glycine soja , and their hybrid seedlings 栽培和野生大豆及其杂交后代幼苗的耐氯性与多胺积累的关系
A rice floral mutant with twin - ovary and dwarf plant was isolated from the progenies of the combination of c2 / mianxiang 5b 摘要在籼稻保持系c2与绵香5b的杂交后代中发现了一个植株显著矮化的双子房突变体。
With the studies during these years , more efficient medium and method for anther culture of hybrid offspring from cultivated and wild rice have been gotten 经多年对栽培稻与野生稻(下称栽野)杂交后代花药培养效率的研究，获得提高栽野稻杂交后代花培效率的培养基和技术方法。
Isoenzyme zymograms had higher polymorphism than protein zymograms . isoenzyme zymograms of hybrids mainly displayed partly complementary zymograms of the two parents in l . davidii var 而亚洲杂种系内杂交，即黄色和克得利亚的杂交后代的蛋白质谱为亲本型，没有明显变异。
In this study of the author , a cross of magnolia liliflora and magnolia " hongyuanbao " with michelia foveolata and michelia yunnanensis produced a high fruit rate of about 81 - 100 percent . these hybrids were highly vigourous 玉兰亚属的紫玉兰和红元宝二乔玉兰与含笑属的金叶含笑、云南含笑的杂交结实率高达81一100 % ，且杂交后代具有较高的活力。
The hybrids not only emerged deeper color in common protein zymograms than in both parents , but also had new bands in mother of l . davidii var . unicolor . but protein zymograms were parental type and had no significant difference in " yellow ' x ' cordelia " 以兰州百合为亲本的杂交后代，蛋白质谱中不仅出现了与亲本同源但比亲本染色加深的带，而且出现了亲本中不存在的新带。
3 . stomata characteristic is very important to improve photosynthetic capacity . the stomata of c4 plants such as echinochloa rusgalli , maize , are larger than c3 plants such as rice and stomata density of c4 plants is less than c3 plants C _ 4植物长芒稗、玉米等气孔较大，但单位面积气孔数少，水稻及其杂交后代的气孔器大小显著小于c _ 4植物，而ygfl的气孔器大小略大于其母本。
Magnolia subgenus yulania , a deciduous tree found in temperate zones , is an important taxonomic group of magnoliaceae . there are in subgenus yulania twenty species , of which one grows in southeast america , three in japan , and most , however , in china widely cultivated in gardens and used as chinese medicine for about 2 , 500 years 本文利用rapd分子标记技术和人工杂交手段对玉兰亚属植物的系统关系和分类地位进行了研究，阐明了玉兰亚属15个种、 11个变异类型和4个品种、 1个人工杂交后代的种间亲缘关系；探讨了玉兰亚属与含笑属和木兰亚属间的系统关系；发现一个新种，建立2个新组。
