查询词典 interspecific

Based on the crossing data among these flatfishes, the relationship between pairwise genetic distance and hybrid fitness was evaluated. The findings indicated that positive relationship might exist between genetic distance and hybrid fitness. The pairwise genetic divergence between species decreased as the interspecific hybrid fitness largened. These results implied that speciation clock might exsit in Pleuronectiformes.

根据这几种鲆鲽鱼的杂交是否可行的试验结果，评价种间遗传距离与杂交可适度的关系，结果表明，这8种鲆鲽鱼类的种间遗传距离与杂交可适度呈显著的负相关(r2 = 0.805，P 0.01)，即种间遗传分化越大，杂交成功的可能性越小，这表明鲆鲽鱼类中可能存在物种进化的不亲和钟。

With spatial sequence taking the place of temporal sequence and succession time as ecological dimension, the niche volumes and overlaps of various species were quantitatively investigated in the manmade florae of Shapotou Area to study the resource-exploiting capacities, interspecific similarities and competition mechanisms of various community components of manmade florae in sand areas in community succession.

在沙坡头沙区人工植被群落区，采用空间序列代替时间序列，并以演替时间为生态位维度，通过定量分析物种的生态位体积和生态位重迭，研究沙区人工植物群落演替过程中群落各组分种对资源的利用能力、种间生态相似性及竞争机制。

Every community was stable relatively. Interspecific association was the loosest and stability was the highest in Q. wutaiensis community. But the insignificant positive association among species showed that Q. wutaiensis community has not reached the stable state, so we still should protect the local natural vegetation reasonably for a long time.

演替系列各群落都具有相对的稳定性，演替顶极辽东栎群落的种间联结性最弱，稳定性最高，但多物种间不显著的正相关说明该地区分布最广、面积最大的辽东栎群落可能尚未达到稳定状态，仍需要对该地区天然植被进行长期保护。

The Dynamical Studies on Biomass , Quality and Interspecific Competition in Annual Forage Crops Swards

一年生混播人工草地生物量，品质及种间竞争的动态研究

Of 12 tomato lines, the analysis on the 4 fruit nourishment quality traits (the contents of vitamin C, total soluble solids and dry matter and ratio of sugar-acid ) was carried out to study the four kinds of disparities, which included the interspecific one, the one between two varieties in the same species , the one between the lines bred by different means in the same variety ,and the one between the different fruit-shaped lines in the same variety .The analytic method of orthogonal comparison of single degree of freedom was applied. The results showed that the line of Lycopersicum pimpinellifolium was better than the average of the lines of L.esculentum in the 4 traits at significant level of 1%, the average of the lines of var.cerasiforme was better than the average of the lines of var.vulgare in the 4 traits at significant level of 5% or 1%,and the two space mutation line(YH02-2 or YH02-6) was better than the average of the other lines of the same variation in the 4 trait, respectively, at significant level of 1%. Of the lines of var.cerasiforme , the lines with pear fruit were lower than the average of the lines with round-shaped or plum-shaped fruits in the 2traits(the contents of vitamin C and total soluble solids), at significant level of 1%,the lines with plum-shaped fruits were higher than the average of the lines with round-shaped fruits, at significant level of 1%,and the lines with yellow-colored fruits(YH02-11) was lower than the average of the lines with red-colored fruits(YH02-1and YH02-7) in the trait of the contents of vitamin C.

对12个品系进行种间、种内变种间、变种内不同选育方式间、变种内不同果实形状间在果实营养品质（果实维生素C含量、可溶性固形物含量、干物质含量和糖酸比）上的差异进行分析，采用统计学上单一自由度正交比较分析法与植物学分类相结合的方法进行分析，结果表明：醋栗番茄种品系YH02-12在4个营养品质性状上，极显著高于普通番茄种品系；樱桃番茄变种品系在4个营养品质性状上的平均水平极显著或显著高于普通番茄变种品系的平均水平；2个空间诱变品系YH02-2、YH02-6在4个营养品质性状上均极显著高于同变种的其他品系的平均水平；樱桃番茄变种品系中，梨形果品系YH02-5、YH02-8的果实维生素C、可溶性固形物含量均极显著地低于樱桃番茄变种中圆形或李形品系的平均水平，李形果品系YH02-9在4个营养品质性状上均极显著地高于圆形果品系的平均水平，黄色圆形果品系YH02-11的果实维生素C偏低于红色圆形果品系YH02-1和YH02-7。

By removed ovary culture after positive and negative hybridization, produced interspecific hybridization, and have improved the hybrid seed through removed ovary culture and induced to shoot by culture medium MS, and produced hybrid F1, the plant of Brassica junce×B.pekinesis, the advantage characteristic of hybrid plant is similar to female nature;By cytology authenticating, chromosome number of F1 young flower bud cell (2n=28), it is the sum of monoploid chromosome number of female parent Brassica junce(2n=36) and male parent B.pekinesis(2n=20); The hybridization to Brassica junce×B.pekinesis, and embryonic bud come from removed ovary culture, and it found another form of plant embryo saving.

以芸薹属植物芥菜型油菜和白菜为研究对象，对其进行常规正反杂交后子房的离体培养，通过离体子房培养获得的杂种种子经MS培养基诱导成苗，获得了芥菜型油菜与白菜的杂种F1代植株，表现出杂种优势；通过细胞学的方法，鉴定了杂种F1幼蕾体的细胞染色体数为2n=28，为母本芥菜型油菜（2n=36）和父本白菜（2n=20）的单倍体染色体数之和；芥菜型油菜与白菜常规杂交后，经离体子房培养获得了&胚性芽&，确立了植物胚挽救的另一种形式。
