The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

结果表明：(1)80种草本植物的种子可以分成两类，第1类由禾本科、莎草科、蓼科和苋科植物的种子组成；第2类由菊科、大戟科、十字花科和伞形科植物的种子组成；(2)聚类图上，只有十字花科植物的种子能较好地与其他科的相区别；(3)在11组同属不同种植物中，有8组植物与亲缘关系不同的其他属的植物混在一起；在7组同种不同亚种或品种植物中，仅有1组植物被聚合在一起。

Genetic losses arise from the influx of 'wild' conspecific pollen into seed orchards.

林木种子园花粉污染是影响种子园种子遗传品质的重要因子，由于野生同种花粉进入种子园而增加遗传损失。

This paper presents a study of Eucalyptus dunnii tissue culture, using its seeds as explants. The results reveal that MS medium is a suitable basic medium for its seeds to germinate and grow; that MS+KT1.0 mg/L+2, 4-D2.0 mg/L+Homocysteine30mg/L is a good medium to induce its seeds to dedifferentiate directly into callus; that H+6-BA2.0 mg/L+IAA0.2 mg/L is a good medium to make its bud on the seedling reproduce more buds; that MS+6-BA2.0 mg/L+NAA0.2 mg/L is a better medium to induce its root on the seedling into callus; that B5+6-BA2.0 mg/L+2, 4-D0.2 mg/L can induce its under-hypocotyl to differentiate into buds; and that B5+Ad2.0 mg/L+IAA0.2 mg/L can induce its under-hypocotyl into callus to generate normal buds.

以邓恩桉种子为外植体，探讨用最少种子快速繁殖最多幼苗的方法，结果表明：MS培养基是较适合邓恩桉种子萌芽和生长的基本培养基；诱导种子直接脱分化成愈伤组织的较佳培养基配方为MS+KT1.0 mg/L+2，4-D2.0 mg/L+半胱氨酸30 mg/L；以邓恩桉实生苗的芽来繁芽的较理想培养基配方为H+BA2.0 mg/L+IAA0.2 mg/L；邓恩桉实生苗的根诱导愈伤组织的较佳培养基配方为MS+6-BA2.0 mg/L+NAA0.2 mg/L；诱导邓恩桉下胚轴分化芽较佳培养基配方为B5+6-BA2.0 mg/L+2，4-D0.2 mg/L；诱导邓恩桉下胚轴脱分化为胚性愈伤组织的较佳培养基配方为B5+Ad2.0 mg/L+IAA0.2 mg/L。

Seeds of Fargesia denudate were treated to accelerated aging and the following indices were measured: seed vigor, T-AOC, activities of anti-oxidative enzymes, contents of MDA, and conductivity, and these indices were also measured on the seeds that differ in size.

为了解缺苞箭竹种子的老化机理和不同大小种子间的差异，对其进行了人工老化处理和大、中、小三组种子的区分，并分别对种子活力，总抗氧化能力，酶活性，丙二醛含量和电导率进行测定。

And Echinochloa crusgalli L. were studied. Both of the aqueous extract from aerial part and root of T. repens inhibited the germination rate of weed seeds, root activity and respiratory rate, and the activities of superoxide dismutase peroxidase and catalase of germinating seeds; enhanced the activity of peroxidase and the content of malondialdehyde.

结果表明，白三叶草地上部分水浸液和根部水浸液显著抑制苘麻和稗草种子的发芽率，降低了杂草种子萌发过程中超氧化物歧化酶，过氧化氢酶的活性，抑制了杂草种子萌发过程中的呼吸速率，根系活力，明显提高了杂草种子过氧化物酶活性和丙二醛的含量。
