OBJECTIVE:Study on the chemical constituents of essential oil from the leaves of Litsea mollia Hemsl.

目的：研究毛叶木姜子叶挥发油的化学成分，并与其果油的化学成分作比较。

Monoterpenes and sesquiterpenes are the major chemial constituents in the oil from the leaves of Litsea mollia Hemsl.They are very different from those of the essential oil from the fruits of Litsea mollia Hemsl.

毛叶木姜子叶挥发油的主要成分为单萜和倍半萜，与果实挥发油的化学成分相差很大。

When the frequency of codon usage of citrus was compared to Homo sapiens, Drosophila melanogaster, Saccharomyces cerevisiac and Escherichia coli, we found that the codon preference is considerably different between citrus and non-plant species. While compared to Arabidopsis thaliana, Lycopersicon esculentum, Oryza sativa and Musa acuminata, we found that the codon preference was identical in dicotyledons, but was different between citrus and monocotyledon, Oryza sativa and Musa acuminate.

将柑橘的密码子使用频率与人、果蝇、酵母和大肠杆菌等不同种类模式生物比较后发现，柑橘密码子的偏爱性与不同种类生物有不同程度的差异；但将柑橘的密码子使用频率与拟南芥、番茄、水稻和尖叶蕉等不同种类的植物相比，发现柑橘密码子的偏爱性与同为双子叶植物的拟南芥、番茄完全一样，而与水稻、尖叶蕉这2种单子叶植物均有较大的差异。

The high frequency plant regeneration system of Medicago truncatula with cotyledonary-node explants was developed through direct shoot organogenesis.

Protoplasts were isolated from cotyledons of eggplant (S. Melongena cv. Yuanjing) in a solution containing 0.75% cellulase R-10, 0.2% Hemicellulase Rhozyme and 0.2% Pectinase.

将茄子子叶原生质体放在0.75％纤维素酶R-10、0.2％半纤维素酶Rhozyme和0.2％果胶酶溶液中分离。

The cellular structure, chemical characterization of foliar endodermis and element cellular distribution were investigated in Pinus bungeana leaves by the fluorescence microscope, Fourier transform infrared microspectroscopy and energy-dispersive X-ray analysis.

应用荧光显微技术、傅里叶变换显微红外光谱分析、扫描电镜及X-射线能谱微区分析等手段，对白皮松子叶、初生叶及2 a生针叶内皮层细胞径向壁的显微结构特征、化学成分，以及在叶子横切面上Na和Cl的微区分布进行分析。

It is composed mainly of monotypic and oligotypic genera and is distributed mainly in eastern Asia.

木通科为双子叶植物纲中较原始的一个小科，多为寡种属和单种属，主要分布于东亚地区。

As an important economic tree species in China, mulberry Morus L.

属多年生双子叶木本植物，是我国重要的经济树种，其叶片是家蚕Bombyx mori L。
