广州清平药市近况
新民
中国中医药信息杂志 , 1998,
Abstract: 近期清平药市成交趋于畅旺,鹿茸、党参、黄芪、冬虫夏草、田鸡油(即雪蛤膏)、淡大云、当归等滋补药材走畅,售价俱缓升。野生小品种药材的来货偏少,价格升多降少,北方产子仁类药材多因受干旱影响而告减产或失收,一些品种如瓜蒌皮(仁)、吐丝子、车前子等品种均因来货稀少,市价较去年9、10月份初上市时对比,有大幅度的上涨。纯正车前子市上较少,江西吉安产车前子有少量货到,每公斤(下同)成交价26元,较前每斤18元速涨44.4%,较今年初每斤13元上涨2倍。多家购进,大货难以搜求。覆盆子货源紧细,每斤由初产时的15元,近而缓升每斤18元,近价快升为每斤28元,较初上市对比,涨幅达86.6,因来货及存货均少,故价升后仍显坚挺,后市将续看升。
《蔓荆子栽培方法介绍》一文的补充
梁国荣,新民
中国中药杂志 , 1985,
Abstract: <正>我们写的《蔓荆子栽培方法介绍》一文发表后,收到各地来信,要求进一步了解蔓荆子栽培特点及种苗来源,现补充说明如下:1.蔓荆子对气候、土壤的要求不甚严格,但最适宜在土地湿润、疏松肥沃的沙质壤土种植。海边、河涌边的沙滩地及山边、鱼塘水库边,堤围、房前屋后或猪牛舍旁种植,均能生长良好。常年干旱瘦瘠的粗砂山岗地不宜种植。
中药竹蜂的捕捉、鉴别及加工方法
新民,梁国荣
中国中药杂志 , 1985,
Abstract: <正>竹蜂(Xylocopadissimilis)主产广东、广西等省。今将我省民间捕捉竹蜂及鉴别与加工方法介绍如下。一、捕捉:①堵穴捕捉:竹蜂多穴居竹林。秋末冬初时,先将穴孔封闭,再把竹砍下,点火加热,使竹蜂闷死,然后破竹取出。亦可在竹竿上人工钻孔,然后在孔内放适量香诱料,引竹蜂做巢,再按上述方法定

蔓荆子栽培方法介绍
新民,梁国荣
中国中药杂志 , 1984,
Abstract: <正>在小寒至大寒季节,选择粗壮的枝条,剪成长约20厘米并带有2~3个节培于苗床,枝距6~15厘米,每枝入土1~2个节,踏实,稻草复盖,浇水。以后适当浇水保持湿润。清明前后移植,株距1.5~2米。定植后可施稀薄沤制人畜粪肥2~3次。幼苗期要勤除草,并做好以下管理措施:①修枝:小寒至大寒期间要剪除老、弱、病枝及徒长枝。使树冠控制在2.5米以内,以利采摘果实。②打顶和弯枝:在新枝1米多高时要及时打顶、太高的要弯枝。即用绳子拴住高枝条的中段,轻轻向下拉于树干或树根头
白花泡桐不定根发生过程中内源激素和rna的变化
新民,梁倩华?
热带亚热带植物学报 , 1996, DOI: 10.3969/j.issn.1005-3395.1996.1.006
Abstract: 白花泡桐(paulowniafortunei(seem.)hemsl.)成年型和幼年型茎切段体外培养时不定根发生过程中内源iaa、ctk和aba含量测定表明:幼年型材料中内源iaa和ctk的含量在诱导的第2天同时达到高峰,而成年型材料中iaa和ctk含量的高峰则在第4天出现.两种类型切段根原基出现的时间都与其内源iaa和ctk的高峰一致.幼年型材料的内源aba含量在第4天达到高峰,随后迅速下降.成年型材料中内源aba则逐步下降.成年型和幼年型材料中rna的变化相同,在诱导的第2天稍有下降,随后显著增加.结果显示,不定根的发生与其内源激素和rna的变化密切相关.

新民,曾振华,梁燕妮
动物学研究 , 2007,
Abstract: 以线粒体细胞色素b (Cyt b) 基因作为分子标记,对中国广西12个地区,以及越南和老挝大壁虎(Gekko gecko) 进行序列测定,获得Cyt b基因424 bp的序列片段,共有7个单倍型。以白脊壁虎和沙虎为外群,用邻接法和最大简约法构建了大壁虎不同地理种群的系统发育关系,其结果显示中国广西4个不同单倍型黑大壁虎之间的平均遗传距离为0.20%—1.20%,越南红大壁虎与老挝红大壁虎之间的平均遗传距离为0.50%,广西宁明红大壁虎与越南红大壁虎和老挝红大壁虎之间平均遗传距离分别为1.70%和2.20%。广西黑大壁虎种群与红大壁虎种群之间的平均遗传距离为8.60%—9.50%,达到了亚种或种分化的差异。

World Journal of Forestry (WJF) , 2016, DOI: 10.12677/WJF.2016.54012
Abstract:
从沙田柚自交和异交花柱转录组测序中鉴定了β-D-木糖苷酶基因序列。该基因全长为2647 bp (GenBank登录号为KU925841),开放阅读框(ORF)为2385 bp,共编码794个氨基酸,编码的蛋白质的分子量为87.30 kDa,理论等电点为5.87。β-D-木糖苷酶基因编码蛋白为亲水性蛋白,含有1个与糖基水解酶家族蛋白相同的保守CAS结构域。β-D-木糖苷酶基因在沙田柚在未授粉花柱中的表达量(RPKM)为0.07,自花授粉1、2、3 d花柱中的表达量(RPKM)分别为43.13、27.84、1.95,在异花授粉1、2、3 d花柱中基因的表达量(RPKM)则分别为33.90、76.14和49.63。系统进化树显示沙田柚β-D-木糖苷酶与甜橙(Citrus sinensis, XM_006468131)和克莱门柚(Citrus clementina, XM_006449591)亲缘关系很近,属于同一进化分支。
β-D-Xylosidase gene was identified from the transcriptome of the self-pollinated style and cross- pollinated style of Citrus grandis var. Shatinyu Hort. It is 2647 bp (GenBank accession number: KU925841) in length with an open reading frame (ORF) of 2385 bp, encoding 794 amino acids with deduced molecular weight of 87.30 kDa, and theoretical pI value of 5.87. Bioinformatics analysis showed that β-D-Xylosidase is a hydrophilic protein, and contained a same conserved CAS structure domain with the glycosyl hydrolase family. The expression of β-D-Xylosidase gene in unfertilized style was 0.07. in 1 - 3 day self-pollinated styles were 43.13, 27.84 and 1.95 respectively. Whereas, the expression of β-D-Xylosidase gene in 1 - 3 day cross-pollinated styles were 33.90, 76.14 and 49.63 respectively. Phylogenetic analysis revealed that β-D-Xylosidase showed closer kinship with that of Citrus sinensis and Citrus clementina, indicating that they belong to the same evolutionary branch.

热带亚热带植物学报 , 1996,
Abstract: The changes in contents of endogenous IAA,CTK, ABA and RNA in the in vitro cultural cutting stem excised from mature and juvenile plant of tube plantlet of Paulownia fortunei(Seem.)Hemsl. were analysed during the development of adventitious root.The endogenous hormones were measured by HPLC. The results showed that the contents of endogenous IAA and CTK in the stem cutting from plantlet(juvenile state)reached their peaks on the second day of culture, whereas the peaks of endogenous IAA and CTK in stem cutting from mature plant (mature state) appeared on the fourth day. From the stem paraffin sections, it was observed that the emergence time of root primordia was the same as that of endogenous IAA and CTK peaks in two states of cultural materials. However, the variation in endogenous ABA content was different between juvenile and mature states. During the rooting period,the level of RNA in both juvenile and mature states of stem cutting slightly decreased on the second day of culture, and then increased markedly.The origin of root primordia come from some peripheral cells of vascular cylinder,and some cells between vascular bundles as well as some pith cells recovering cell division. But the emergence of root primordia in mature stem cutting was 2 days later than that in juvenile cutting of plantlets,and the number of adventitious root in the former was less than that in the latter.

Abstract: Samples of Gekko gecko were collected from 12 areas of Guangxi China,Vietnam and Laos.Four hundred and twenty four base pairs of G.gecko mitochondrial Cyt b gene were sequenced and seven haplotypes were found.Gekko vittatus and Teratoscincus keyserlingii acting as outgroups,the phylogenetic trees of the G.gecko constructed using NJ and MP methods showed that the average genetic distances were:0.20%-1.20% between four haplotypes of black G.gecko from Guangxi China;0.50% between Vietnamese and Laotian red G.gecko;1.70% between Ningming and Vietnamese red G.gecko;2.20% between Guangxi and Laotian red G.gecko;8.60%-9.50% between black G.gecko from Guangxi and all red G.gecko.The genetic difference of black and red G.gecko reached the species or subspecies differentiation.
