The comparison with its mother Chinese tulip tree and father American tulip tree have been made The results show:(1)The air-dried density is 0.544g/cm3, the radial, tangential and volumetric shrinkage are respectively 5.06%、9.61% and 14.91%.(2)The longitudinal compress strength, MOR and MOE are respectively 42.1Mpa, 84.5MPa and 7.4GPa. Every value of physical and mechanical properties is between the Chinese tulip tree and the American tree.
结果表明：杂种鹅掌楸的气干密度为0.544g/cm3，径向、弦向和体积全干缩率分别为5.06%、9.61%和14.91%；主要强度指标顺纹抗压强度、抗弯强度及抗弯弹性模量分别为42.1Mpa、84.5MPa 和7.4GPa；各项物理力学性质均介于中国鹅掌楸和北美鹅掌楸之间。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.
结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.
研究结果表明，鹅掌楸组培再生过程中，过氧化氢酶活性与H2O2含量变化呈负相关，CAT活性较高时，H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关，H2O2可能作为信号因子在芽分化过程中发挥重要作用；IAA氧化酶活性呈现先下降后增加的变化规律，从而影响IAA氧化降解途径，调控细胞分裂素与生长素含量的比值，影响鹅掌楸芽的再生；PPO活性随培养时间的增加而升高，引起组培苗的褐变或玻璃化，甚至生长畸形。

The others were discovered in Liriodendron tulipifera except for cyanidin and galactose, so the three groups could be identified partially by cyanidin and galactose.
北美鹅掌楸花被片除不含有花青素和半乳糖外，其它成分同鹅掌楸和杂交鹅掌楸，因此花青素和半乳糖可作为三大类群的识别依据之一。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.
本文对鹅掌楸、北美鹅掌楸和杂交F_1的花果共11 个数量性状进行分析，并应用高效液相色谱对上述三大类群花被片类黄酮糖苷配基和结合糖及类胡萝卜素进行了定性和定量研究，结果如下：鹅掌楸和杂交鹅掌楸花被片类黄酮糖苷配基为花青素、6-羟基黄酮和反式查尔酮，糖苷配基结合糖为葡萄糖、鼠李糖和半乳糖；类胡萝卜素为β-胡萝卜素和番茄红素。

With higher content of β-carotene. The length and width of perianth segment(inner 2 ring) were osculant, the former showed matroclinous inheritance, the latter showed patroclinal inheritance, so Liriodendron interspecific hybrids with bigger perianth segment could be selected by Liriodendron chinense?
杂交鹅掌楸内两轮花被片长度和宽度为双亲中间型，分别偏向母本和父本，用内两轮花被片较宽的鹅掌楸作母本，内两轮花被片较长的北美鹅掌楸作父本，有望选育出大花的杂交鹅掌楸个体。
