不同产地白术根茎解剖比较

为鉴定白术Atractylodes macrocephala道地性药材,采用滑走切片法制作永久制片,在显微水平上比较了不同产地白术的解剖特征。试验表明,木质部宽、树皮宽、木皮比（木质部与韧皮部宽度比）、导管密度、油室直径和油室密度等参数在不同产地间均存在着极显著的差异（P〈0．01）,反映了不同产地的白术根茎在解剖构造上的不一致性;但差异的表现却不尽相同,错综复杂,引起差异的遗传和环境上的因素在解剖构造上是一个综合表现。油室面积比例可作为衡量有效成分的一个较好的指标。表7参16

Simultaneous detection of <Emphasis Type="Italic">Japanese yam mosaic virus</Emphasis> and <Emphasis Type="Italic">Yam mild mosaic virus</Emphasis> from yam leaves using a tube capture reverse transcription-polymerase chain reaction assay

To detect Japanese yam mosaic virus (JYMV) and Yam mild mosaic virus (YMMV) in yam plants in Japan, we developed a duplex RT-PCR assay consisting of a tube-capture procedure followed by one-step RT-PCR with two primer pairs. A 241-bp fragment of the coat protein region of JYMV and a 174-bp fragment of the nuclear inclusion protein b region of YMMV were amplified, thus identifying the two viruses from yam plants cultivated in Yamaguchi Prefecture in 2007. All water yam plants examined were infected with YMMV alone. All the Japanese yam and Chinese yam plants were infected with either JYMV alone or both JYMV and YMMV, suggesting that YMMV and JYMV are prevalent among field-grown yam plants.     

创杉木种子园种子高产记录之研究

横畈林场杉木１．５代种子园１９８５年嫁接建成，由于采取综合技术措施，１９９１年平均每公顷产种子１０５ｋｇ，球果出籽率５．７％，进入盛果期的１９９５年平均每公顷产种子２４１．５ｋｇ，球果出籽率６．３％，创全国同类种子园的最高记录。     

Broad bean wilt virus 2 in yams

We identified Broad bean wilt virus 2 (BBWV-2) in yams based on particle morphology, test plant symptoms, protein features, aphid transmission, and molecular classification using nucleotide sequences of coat protein genes.     

畜禽交易市场病害畜禽无害化处理

杭州城北畜禽交易市场始建于2004年,年交易家禽2000万羽左右,为浙江省最大的活禽交易市场之一。该市场位于余杭区良诸镇,交通便利,来往人员复杂。市场内每天交易的禽类来源广泛,品种繁多,数额较大,给疾病传播造成了较大隐患。为有效防控市场动物疫情,市场通过加大投资,完善动物防疫条件,加强生物安全设施建设,强化动物卫生法制管理,对病害畜禽实行无害化处理,通过近2年来的运作,实效明显,较好的控制了疫病的传播。下面将有关工作情况报道如下:1取得的经验1.1突出重点,加强动物卫生防疫基础设施建设动物卫生防疫基础设施对于疫病防治至关重要…
