Abstract:以稻褐飞虱生物型Ⅱ、盂加拉型、九龙江型的长翅型(M)、短翅型(B)的遗传纯系为试验材料,观察了生物型的亲代翅型对子代的遗传效应以及水稻生育期和虫口密度对翅型遗传的影响。结果表明:稻褐飞虱3种生物型子代的翅型表型与亲代的遗传关系密切,但各生物型子代的翅型表型存在差异;在多头饲养条件下,水稻生育期对3种生物型翅型遗传的调节作用较为明显,但这种影响同亲代翅型和褐飞虱所属生物型有关;在单头饲养条件下,稻株生育期对不同生物型翅型分化几乎没有影响,但亲本遗传的制约依然存在。

Abstract:5头健康雄性去势水牛(2~3岁、体重300~500kg),经粪便和Dot-ELISA检测确认无肝片吸虫感染。每头水牛一次经口感染1600个肝片吸虫囊蚴,研究急性感染(一次大剂量)肝片吸虫对水牛安替比林代谢动力学影响。用HPLC法测定血浆安替比林(AP)及其代谢物的浓度,分析其动力学参数。每周定时采血测定血清酶水平变化。结果表明:水牛急性感染肝片吸虫后急性期安替比林静脉给药后的动力学参数没有显著变化.在慢性期,血浆消除半衰期T1/2β延长41.42%,总消除率CL下降60.10%,表观分布容积Vdss减小43.61%,平均保留时间MRT上升41.16%,血浆浓度-时间曲线下面积AUC增大150.61%。AP给药后48h内各代谢物的形成比率及尿清除率与对照期相比在急性期无显著差异,而慢性期极显著降低,AP试验结果与血浆酶水平变化相一致。

Abstract:对天津开发区滨海几种人工植被的碳净贮量、平均积累速率及其分配格局作了初步研究:碳净贮量从大到小依次为乔-灌-草群落(12.93 t/hm2)>灌木群落(12.205 t/hm2)>草本群落(4.725 L/hm2)>灌-草群落(1.61 t/hm2)。平均碳净积累速率是灌木群落(4.07 t/hm2·a)>乔-灌-草群落(3.23 t/hm2·a)>草本群落(1.18 t/hm2·a)>灌-草群落(0.81 t/hm2·a)。以木本植物为主的群落中,主要依靠地上部分贮存碳,并且随着层次的增加,地上部分贮量所占百分比有上升的趋势。乔-灌-草群落中,乔木贮量占群落总净贮量的84.49%、灌木占14.81%、草本仅0.70%;灌-草群落中,灌木占91.95%,草本占8.05%。乔木种的各器官碳净贮量中,皮所占比例最小,根、枝、干三者比例较为接近,都在30%左右;灌木种则都是枝>根。
