三种原产中国的野生稻和栽培稻外稃表面乳突结构的比较观察研究

 用扫描电镜对原产中国的瘤粒野生稻（Oryza meyeriana Baill. subsp. tuberculata Wu），药用野生稻（Oryza officinalis Wall. ex Watt.），普通野生稻（Oryza rufipogon Griff. ）的外稃表面的显微结构与栽培稻（Oryza sativa L.）进行了比较研究。观察到栽培稻与瘤粒野生稻在一系列性状上差异最大，其次是药用野生稻，而最相似的是普通野生稻。应用性状数码的方法对种间的相似性作了比较。     

迷迭香挥发油提取工艺优化及其化学成分分析

采用水蒸气蒸馏法提取迷迭香(Rosmarinus officindis L.)挥发油,运用正交设计优化提取工艺.结果表明,迷迭香挥发油最佳提取工艺条件为迷迭香剪成1 cm长的小段、料水质量比1∶15、浸泡时间3h、提取时间4h,此条件下挥发油的得率为1.870％.运用GC-MS技术分析并比较了迷迭香鲜样和干样挥发油的化学成分,结果表明二者化学成分基本相同,药材阴干后挥发油品质没有受到明显影响.     

FAAS和HG-AFS用于玉竹中微量元素溶出特性的研究

[目的]研究玉竹中微量元素的溶出特性。[方法]以HN03-HClO4为消解体系,应用火焰原子吸收法（FAAS）和氢化物发生一原子荧光法（HG—AFS）测定邵东玉竹中12种微量元素Fe、Cu、Zn、Mn、Ni、Ph、Cd、cr、As、Sb、Se和Hg的含量,同时比较微波提取法、超声提取法和传统煎煮法对玉竹中12种微量元素溶出的情况。[结果]试样中各元素含量的相对偏差（RSD）为0．04％～4．37％,加标回收率为90．0％-106．O％。玉竹溶出液中含量较多元素的顺序为：Cu〉Fe〉Zn〉Mn,其余元素的含量均很少。[结论]微波萃取法在有效成分的提取中具有快速、高效和安全等特点。FAAS和HG．AFS法快速、准确、灵敏度高,适用于玉竹中微量元素的含量测定。

山茱萸良种繁育栽植技术

经多次实地踏查和走访调研总结,山茱萸在陕西省境内的秦巴山区15县生长具有得天独厚的优势,主要分布在陕西的汉中、商洛地区。尤其在周至、眉县、太白、佛坪、洋县、丹凤等地发现有成片的自然分布,到目前已成为药材山茱萸的主产区,2014年2月国家质检总局正式批准"周至县山茱萸"为国家地理标志的保护产品。结合各地域立地条件,特将选育的良种进行科学栽培,实现优产丰产。     

山茱萸肉酶法液化工艺研究

本试验对果胶酶在不同条件下液化山茱萸肉进行了研究,结果表明,山茱萸肉酶法液化最佳工艺参数为：酶解温度４５℃、酶解酶量１．０ｍｇ．ｇ－１、酶解时间２．５ｈ、酶解水量２０倍。     

厚朴苗木质量与幼树生长关系的研究

为提高厚朴造林质量,开展了苗木地径、亩高与厚朴幼树生长关系的研究,结果表明：厚朴苗木高度对幼树生长无明显的影响,苗木过高反而会降低造林成活率;苗木地径大于0．9cm时,地径对幼树生长也无显著的影响。因此,厚朴苗木不宜以苗高为分级依据。厚朴苗木的适宜高度可从便于起苗、运输、栽种等生产环节来确定。厚朴苗木地径的分级,优质苗的下限也不应大于0.9cm。     

Long Term Rearing of Cuttlefish in a Small Scale Facility

Cephalopods are arguably the most complex and fascinating aquatic invertebrate taxa. Except for a few well known exceptions, this group of organisms has been a challenge to study primarily due to difficulties in rearing and maintaining these animals in a small laboratory setting. Our knowledge about cephalopod rearing comes mainly from large marine centers, with much less known about small scale rearing facilities. This paper describes a bench top (ca. 450 litre) aquarium system that is relatively inexpensive, easy to maintain, and suitable for long term rearing of cuttlefish in the laboratory. This closed aquarium system uses artificial sea water and a biological filter to remove/recycle nitrogenous wastes. The simple design of this system can be easily replicated by inland researchers interested in studying cuttlefish but who have been thwarted by the lack of suitable housing facilities. This revised version was published online in August 2006 with corrections to the Cover Date.     

The effects of tank colours on the growth and survival of cuttlefish (Sepia officinalis,Linnaeus 1758) hatchlings and juveniles

The effects of different tank colours (white, yellow sandy and black) on the growth, mortality and biomass production were studied for hatchling and early juvenile cuttlefish. For hatchlings, the use of different colour tanks did not promote differences in growth due to the higher variability (standard deviation) found in the white‐ and sand‐coloured tanks. Black tanks promoted the lowest and highest values for total mortality and biomass respectively. For juveniles, the use of different tank colours promoted different growth (P<0.05), but not mortality. Black tanks promoted the best results in terms of growth and biomass. The results obtained in the present study advise the use of black (or dark colour) tanks in the hatchling and early juvenile stages to reduce the standard deviations associated with growth, mortality and biomass production. This will contribute to minimize problems associated with slow and fast growers and competition.     

上海地区引种栽培的鼠尾草精油的季节性变化

对上海地区引种栽培的一年生和三年生的鼠尾草植物不同季节（夏季-8月,秋季-10月,冬季-1月,春季-4月）的叶子,用水蒸气蒸馏法提取精油,并且用GC和GC/MS方法进行分析.结果表明一年生和三年生鼠尾草精油成分和含量在不同的季节有很大的变化,精油的主要成分是侧柏酮（29.53%～49.70%）,其次是樟脑（11.70%～22.72%）,1,8桉叶油素（3.39%～12.08%）,绿花白千层醇（4.09%～11.49%）,蒎烯（0.95%～11.19%）,β石竹烯（2.76%～10.58%）,龙脑（1.79%～9.86%）和β芹子烯（2.94%～7. 39%）.一年生和三年生鼠尾草精油含有率在整个生长季节中八月达最高,三年生鼠尾草精油含量要高于一年生鼠尾草.
