Other courses like dendrology for gardening, taxonomy of seed plants, plant classification or plant systematics may be similar or overlap in some degrees. However, dendrology focuses on woody plants, especially on trees from gymnosperms and dicotylerdons of angiosperms. Dendrology for gardening is more suitable for students from specialties relating to gardening.
类似并可以在一定程度上起替代的课程为园林树木学、种子植物分类学、植物分类学或植物系统学，但树木学主要侧重于木本植物的分类，而且主要集中在裸子植物和被子植物的双子叶植物纲上中；园林树木学则主要适用于园林相关专业的学生。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.
DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。

Using nuclear DNA C-values for 539 angiosperms in China, we examined the variation of these values among growth forms and taxonomic groups and the relationship of these values with invasiveness. Mean DNA C-value of the 539 angiosperm species was 4.06 pg. Mean DNA C-value was(1) significantly lower for woody species (1.84 pg) than for herbaceous species(5.02 pg);(2) significantly lower for 360 dicots (2.20 pg) than for 179 monocots (7.80 pg);(3) significantly lower for annuals (2.78 pg) than for perennials(6.65 pg);(4) significantly lower for 134 weed species (1.93 pg) than for herbaceous non-weeds (6.75 pg) and for several families that have an unusually high proportion of weed species;(5) significantly lower for 47 exotic weed species (1.76 pg) than for 134 native weeds (1.93 pg), but significantly lower than that of "non-weedy" herbaceous species (6.75 pg);(6) lower for weeds than for "non-weedy" species in same genus or family; and (7) in herbaceous species, generally lower for weedy compared to "non-weedy" species, with some exceptions such as Avena fatua, whose DNA C-value is as high as 14.15 pg, contrarily, and some "non-weedy" herbaceous species in Cruciferae and Cucurbitaceae with very low values.
统计了中国境内有分布的539种被子植物的DNA C-值，分析了它们在不同分类群、生活型、倍性、生活史类型以及在杂草和非杂草类群中的分布情况，主要结果如下：(1)539种被子植物DNA C-值平均为4.06 pg，其中木本植物的DNA C-值平均为1.84 pg，低于草本植物的平均值(5.02 pg)；(2)双子叶植物(360种)的DNA C-值平均为2.20 pg，极明显地小于单子叶植物(179种)的平均值(7.80 pg)；(3)1年生植物的DNA C-值平均为2.78 pg，明显小于多年植物的平均DNA C-值(6.65 pg)；(4)134种杂草的DNA C-值平均为1.93 pg，明显小于非杂草草本植物的平均值(6.75 pg)，含杂草较多的科，平均DNA C-值相对较小；(5)统计的47种入侵杂草的DNA C-值平均为1.76 pg，略小于134种杂草的平均DNA C-值(1.93 pg)，极显著地小于非杂草性草本植物(6.75 pg)；(6)以科为单位，不同科的DNA C-值存在着极大的差异；(7)DNA C-值与染色体倍性的关系并不明显，但是，随着倍性的增加，基因组变小；(8)在同一科、属中，与非杂草相比，典型杂草的DNA C-值往往偏小；(9)总体上杂草或杂草性强的植物，它们的DNA C-值比非杂草性植物的要小。

Because homeotic gene mutation and floral organ variation is a direct relationship,therefore the mutant application is the current functional genomics study developmentdirection. We discovered one mutant ah from line 458, which was a line ofthe twin-seedling strain W2555.ln this study, we have investigated the morphogenesisprogress, genetic analysis of mutant traits and molecular tagging of related gene.
目前，由于在水稻中发现的花器官突变体很少，所以对水稻花发育的研究主要是利用双子叶植物MAS-box基因的保守序列设计引物，在水稻基因组或者cDNA文库中筛选与双子叶植物花器官发育相对应的MADS基因，因为同源异型基因的突变与花器官的变异是直接对应的关系，所以突变体的应用是当前功能基因组学的发展方向。

In this review, we use Arabidopsis thaliana and Oryza sativa as examples, and summarize the study results of floral homeotic MADS-box genes in two major groups of angiosperms — core eudicots and monocots — over the past decade. Our aim was to review the functional conservation and diversity of floral homeotic MADS-box genes in angiosperms and discuss whether the ABCDE model has been conserved in monocotyledons.

The galactosyl oligosaccharides of raffinose series are widely distributed in seeds of many species and are localized in tissues that remain viable after desiccation, including the embryo and aleurone layer of cereals, cotyledons and axis tissues of legumes and other dicots.
棉子糖半乳糖苷系列寡糖广泛分布在许多种植物种子中，并存在于干燥后仍能保持活力的组织内，如禾谷类种子的胚及糊粉层，豆类及其他双子叶植物的子叶和胚轴组织等。棉子糖半乳糖苷系列寡糖在禾谷类种子的非自溶性中央胚乳中不合成，但存在于蓖麻种子的自溶性胚乳细胞中。

These large differences were predominantly caused by differences in numbers of annual dicots and perennial, mainly woodland dicots while the higher total species numbers in the Netherlands were mainly the result of an increase in all annual species.
这些大的差异主要是所造成的差异，在人数每年双子叶植物和多年生，林地主要是双子叶植物，而高占总种数的数目，在荷兰，主要是由于增加了，每年都种。
