The results are as follows: 1 mean length and weight tend to increase while dominant length and weight groups are noted to be increasing from Oct. 2004 to Sep. 2007; 2 by using length-weight formula, calculated weight value at the same length is higher for track-data than that for background-data; 3 growth parameters of L∞, W∞ and K respectively increase from 140.5 mm, 36.5 g and 0.28 a-1 to 186.0 mm, 118.5 g and 0.36 a-1 after artificial reef deployment; 4 appreciable increases are noted in body length and weight growth rate after artificial reef deployment, and inflexion age of weight growth increases from 2.55 to 2.58 years after artificial reef deployment; 5 there is an increase in critical biomass age from 3.21 to 3.77 years after artificial reef deployment; 6 there is a decrease in total instantaneous population mortality from 1.065 to 0.75 per year after artificial reef deployment; and 7 the overall population biomass of small yellow croaker stands at 131.5 tons.

结果表明：投礁后小黄鱼的平均体长和体重均呈上升趋势，优势体长组和体重组均向高值移动；同等体长情况下由投礁后体长体重关系式估算的体重比用投礁前的体长体重关系式估算的值大；投礁后小黄鱼个体生长方程的参数 L∞、W∞、K 值分别从投礁前的140.5 mm、36.5 g和0.28 a-1增加到186.0 mm、118.5 g和0.36 a-1；投礁后体长与体重生长速度与投礁前相比有所增大，且体重生长的拐点年龄从投礁前2.55 a提高到2007年的2.58 a；小黄鱼种群生物量增长的临界年龄从投礁前的3.21 a提高到3.77 a；小黄鱼种群的总瞬时死亡率从投礁前的1.065 a-1减小到0.75 a-1；鱼礁区小黄鱼资源量约

Effects of different medias on the population growth of three marine ciliates, Euplotes vannus Müller, 1786, Uronema marinum Dujardin, 1841 and Paranophrys magna Borror, 1972, were investigated using experimental ecological method in beef extract and rice grain medium. Analysis of data revealed that the natural growth rate and the population densities of E.

为揭示不同培养液对纤毛虫种群增长的影响，本工作利用实验生态学方法对海水养殖水体中3种常见的纤毛虫原生动物，扇形游仆虫（Euplotes vannus Müller， 1786）、海洋尾丝虫（Uronema marinum Dujardin， 1841）和巨大拟阿脑虫（Paranophrys magna Borror， 1972）在两种培养液中的种群生长过程进行了探讨。

One disease resistance segregating population 3B789, derived from "EM85/Torfrida//Wen6/3/3*Jing411/4/Nongdal89", was selected for SSR analysis using BSA approach. An EST-SSR marker Xcau33 was found to be co-segregated with the resistance gene Pm4b in a 231 plants population and could be used for marker-assisted selection of both Pm4a and Pm4b locus.Forty accessions of wild emmer T. turgidum var.

利用一个来自杂交组合"EM85/Torfrida∥温6/3/3~*京411/4/农大189"的抗病分离群体3B789，通过BSA法建立SSR标记，发现在分离群体3B789的231个单株中，EST-SSR标记Xcau33与抗病基因Pm4b表现共分离，能够在辅助选择Pm4a和Pm4b基因的育种工作中应用。
