铯－134在幼龄茶树叶片中的分布特点

茶树上喷洒￣（１３４）Ｃｓ后，老叶上的沉积量和新叶上的吸收量均按指数回归形式下降，下降的速率以老叶上最快，春茶叶和夏茶叶上次之，秋茶叶上最慢；灌溉和土壤中拌入￣（１３４）Ｃｓ后，茶叶对￣（１３４）Ｃｓ的吸收分两个阶段进行，前期随着时间延长而增加。后期则减少。吸收量有个最大值；茶叶中￣（１３４）Ｃｓ的含量在喷洒情况下比灌溉和拌土的高。     

Studies on Tomato Seedling Quality Indices Under Simulated Shipping and Storage Conditions

Indices of the tomato seedling quality maintenance level after production before field planting were studied through simulated experiments, small--scale operation, indoor analyses and measurements, and field observation. The results showed that under simulated shipping and storage conditions, seedling quality change following different durations (days) of shipping and storage was correlated significantly or even very significantly with certain physiological and morphological indices. With various measured indices following different periods of shipping and storage treatment subjected to multinomial successive regressive correlation analysis, the principal factors influencing seedling quality maintenance level are identified to be chlorophyll content→dry short weight→ leaf freshness index in order of their importance. Significance analysis with multinomial fitted equation indicated that correlations between any one of above three factors and the growth index after field planting reached very significant difference level.

Acupuncture for general veterinary practice.

Since the International Society of Veterinary Acupuncture (IVAS) was founded in 1974, acupuncture (AP) has received greater acceptance by veterinary professionals throughout the world. This article introduces some important animal diseases that respond well to AP therapy. These include resuscitation of small animals, treatment of anoestrous gilts and sows, bovine reproductive disease, canine vertebral problems and equine backpain, etc. Conventional medicine considers these to be difficult cases to treat. Veterinarians have become more aware of the benefits of AP especially for those diseases, thanks to the efforts of experienced practitioners and scientists, and the many published reports on veterinary AP that have introduced some good indications for AP therapy in veterinary practice. Possible mechanisms behind the effectiveness of AP are discussed. This article aims to introduce veterinarians to good indications for AP to initiate their interest in the practice of AP. Although this is a rapidly expanding field, a long march must begin with one step. We wish this article to be the shoes for such a march. For more information on veterinary AP, contact IVAS , P.O. Box 1478, Longmont, CO.. 80502, USA (http://www.ivas.org), or your national veterinary acupuncture society (http://www.komvet.at/ ivadkom/vapsocs.htm).     

辣椒夏季品比试验报告

为了考察我公司新推广品种及新配组合在高温伏旱状况下的适应性，我们于2003年5月7日在公司试验基地进行了品种对比试验。结果表明新推广品种中有九个品种或组合为极耐热或耐热，一个品种耐热性稍差。新配组合中部分表现优良，有推广前景。     

槟榔红色素的抗氧化活性

测定槟榔红色素(areca red pigment,AP)对 DPPH·和·OH的清除能力、对脂质体过氧化的抑制能力、对Fe2+的络合能力,并测定其还原能力.结果表明:槟榔色素对DPPH·、·OH的清除能力较强:对脂质体过氧化的抑制能力很强,抑制率高达79.84%;与VE、没食子酸(gallic acid,GA)、BHT相比,槟榔色素的还原力、对Fe2+的络合能力较弱.说明槟榔红色素是较好的抗氧化剂.     

不同稀释液对藏獒精液保存效果的影响

比较了8种稀释液在藏獒精液冷冻保存和低、常温保存(5 ℃,10 ℃,15 ℃,20 ℃)的效果.结果表明:2号和8号稀释液在冷冻保存时效果最好,精子活力和顶体完整率分别达到0.40和49%,与对照组相比差异显著(P<0.05).在藏獒的低温、常温保存试验中,所有稀释液在15 ℃时保存时间最长,综合考虑,7号液保存效果最好;在15℃时精子平均存活时间为103 h,显著高于对照组和其它稀释液(P<0.05).
