The rank-sum test is a nonparametric method used in variety evaluation.

秩和比较作为一种非参数方法，虽在作物品种评价方面得到一定的应用，但对多品种多性状的综合评定仍缺乏必要的统计测验基础。

The rank-sum test is a nonparametric method used in variety evaluation.However,the hypothesis testing theory of this method hasn't been established for multi-trait comprehensive ranking.

First, use the methods of anatomy, palynology, embryology and morphology, every species were carried out meticulous analysis on each other properties distinction, evolutional relationship and the relation between they and environment.

首先，应用解剖学、孢粉学、胚胎学和形态学等方法对各个种之间的性状差异、演化关系及其与环境的相互关系等方面进行了深入细致的研究。

Upon these plants, some germplasm resources were collected at home and abroard, and their morphology, palynology, cytology, growth and development habit, fruit economy characteristics were studied. The extraction methods for DNA of Lonicera Caerulea L. and reaction system of RAPD were also discussed in the project. And it was the first time to study the genetic diversity, relationship and classification of Lonicera Caerulea L on wild resource in Northeast of China and subsection using RAPD.

针对这些问题，我们收集了国内外的种质资源，从形态学、孢粉学、细胞学、生长发育习性和果实经济生物学性状等方面对东北地区野生蓝靛果忍冬的生物学特性进行了系统研究；对蓝靛果忍冬DNA的提取方法和RAPD的反应体系进行了详细探讨，并首次运用RAPD技术分别对东北地区野生资源和蓝果亚组种间的遗传多样性和亲缘关系、分类等问题进行了研究和分析。

The organism, found in the Patagonian rainforest, naturally produces a mixture of chemicals that is remarkably similar to diesel .

该物种在巴塔哥尼亚的雨林里被发现，它能分泌一种天然的化学物质，性状类似柴油。

Expression patterns of these Saintpaulia homologs thus were compared between flower buds of zygomorphic wild type and actinomorphic peloria.

结果显示，SiCYC1A和SiCYC1B在两种对称性状中的背侧花瓣上都有表现。

Polyembryonyoccurs in 〓 and 〓 caryopsis of cross SB-1 X Balilla(Balilla is non-polyembryony),and in 〓 caryopsis ofits reciprocal the polyembryony is observed but not in 〓caropsis.

在正交（SB-1 X 马来红，马来红不具多胚特性）〓及〓颖果中都出现了多胚苗，反交（马来红 X SB-1）的〓颖果未出现多胚苗，但其〓颖果观察到多胚苗，表明SB-1的多胚不是合子裂生产生的，而是胚囊的一种特殊性状。
