Effect of Arbuscular mycorrhiza on steppe plants and infection rate of steppe plants varied with species of the mycorrhiza and plants. The effect on Agrostis hugoniana was greater than on Festuca rubra in all inoculation treatments, and the effect of the combinations of Festuca rubra+Glomus mosseae and Agrostis hugoniana+Glomus intraradices were more significant than others.

4同一、不同AM真菌对不同或同一草地植物的侵染及所产生的菌根效应具有不同程度的差异，穗序剪股颖各接种处理普遍优于紫羊毛，紫羊毛＋Glomus mosseae穗序剪股颖＋Glomus intyraradices优于同组其他接种处理的趋势较为明显。

The comparison of the effects on the two plants indicated that Ranunculusjaponicus, Aconitum sinomontanum,Ⅰ pomoea cairica, Aconitum gymnandrum and Anaphalis lactea showed significant effects on the two plants (their M values were separately -0.87,-0.82, 0.71,-0.68 and 0.62) and consequently these five plants were hopeful to be developed into new herbicides of plant origin.

综合比较对2种植物的综合化感效应指数差异，毛茛、高乌头、五爪金龙(Ⅰpomoea cairica)、露蕊乌头和乳白香青作用效果显著（其M差值分别是：-0.87、-0.82、-0.71、-0.68和-0.62），这5种植物有望开发新型植物源除草剂。

Seed plants; comprises the Angiospermae and Gymnospermae; in some classification systems Spermatophyta is coordinate with Pteridophyta (spore producing plants having vascular tissue and roots) and Bryophyta (spore producing plants lacking vascular tissue and roots).

种子植物；包含被子植物部和裸子植物部；在一些分类中，种子植物等同于蕨类植物（其孢子能生成有维管组织和根的植物）和苔藓植物（其孢子生成的植物没有维管组织和根）。

Pushed by Hamilton's theory, some botanists have discovered and testified aposematic coloration do exist in plants such as autumn leaves, young leaves of tropical rainforests, some thorny plants and reproductive organs of plants whereas some of them are still obscure or controversial.

起源于猎物－捕食者关系的警戒色理论在动物界得到了充分研究，但植物警戒色却不为人所知，直到2001年Hamilton关于秋季树叶颜色的信号假说公开发表后，才引起人们对植物警戒色的初步研究。

Aposematic coloration should not only belong to animals, plants could evolve it too if necessary for plant fitness. The temporal and spatial colour polymorphism in vegetative parts of plants deserve more research and the defense tradeoff hypothesis predicts the possibility of aposematism may occur in the reproductive organs of plants.

如今在早秋变色树种、幼叶、多刺植物、植物繁殖器官都发现了警戒色的一些例证，尽管有些还不太明确甚至存在争议，但至少为植物警戒色的进一步研究奠定了基础。

However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...

本研究在初步明确兰州市坪用黑麦草内生真菌及其病原真菌多样性的基础上，在实验室、温室和田间开展了系列研究，比较了带内生真菌和不带内生真菌的黑麦草在离体和整株条件下对细交链孢、离蠕孢、燕麦镰孢、新月弯孢、小孢壳二孢、锐顶镰孢、厚垣镰孢、尖镰孢、腐皮镰孢和粉红粘帚霉等10种病原真菌的抗病性，测定了E+和E-植株数种保护酶活性及其生物碱含量的变化。

The first part is to selection 16 plants,including kummerowia striata、Lotus corniculatus、Cajanus caja、Indigofera pseudotinctoria etc leguminous plants, and Cynodon dactylon、Vitex negundo etc other family plants. The second part is the experiment of compound combination:namely,A: Eragrostis curvula (60%)+ Lotus corniculatus(20%)+ Trifolium repens(20%)、B:Cynodon dactylon(60%)+ kummerowia striata(20%)+ Lotus corniculatus (20%)、C: Festuca arundinacea(40%)+ Festuca rubra (20%)+ Vitex negundo(15%)+ Lespedeza formosa(10%)+ Indigofera pseudotinctoria(15%)、D: Festuca arundinacea (40%)+ Festuca rubra (20%)+ Indigofera pseudotinctoria (15%)+ Rhus chinnensis (15%)+ Robinia pseudoacacia (10%).

本研究分两部分进行，第一部分为：防护植物筛选试验，包括鸡眼草、百脉根、木豆和马棘等豆科植物与狗牙根、荆条等其它科植物共16种；第二部分为四种人工混播组合：即，A弯叶画眉草(60%+百脉根(20%)+白三叶(20%)、B狗牙根(60%+鸡眼草(20%)+百脉根(20%)、C高羊茅(40%+紫羊茅(20%)+荆条(15%)+美丽胡枝子(10%)+马棘(15%)、D高羊茅(40%+紫羊茅(20%)+马棘(15%)+盐肤木(15%)+刺槐(10%)。

These male sterile transgenic plants with TA29 Barnase gene have the same horticultural characters which can be also inherited steadily by plants in next generation as non transgenic ones. But their flowers bear fully catagenetic stamen lacking pollens, normal fragrant nectaries and strong pistils able to receive pollens from other plants or different cultivars and set seeds. At the meantime, the sterility i...

带有TA 2 9 Barnase基因的雄性不育植株的园艺学性状与未转化植株相同，并且其性状在后代中稳定不变；不育植株的花朵表现雄蕊完全退化，但蜜腺和雌蕊健全，能接受外来花粉，杂交结实率较高；同时，雄性不育植株的不育性在后代中出现分离，不育株率占 12 。5%～ 85.7%；此外，不育性状具有镶嵌性

In addition,the leaves of the control plants appeared to be much reder than the transgenic tomato,and the change were obvious followed by far from the treated time at low temperature,which suggested that the constituently expression of the chloroplast sHSP had some protective fountions to the tomato at low temperature.2 Effect on contents of MDAMDA is the product that membrane lipid peroxide and the contents of MDA in plants can reflect the degree of the damage that the plants are encountered to some extent.

低温处理6周后，转基因苗叶片中chla，cib含量及叶绿素总量明显高于对照，反应叶绿体中类囊体垛叠程度的chla／the比值也大于对照，可见冷害条件下转基因植株体内叶绿素的破坏程度小。4））t％hs用：低温Al：Pll6周，测定植物光合作用的重要指标净光合速率、蒸腾速率、气孔导度、胞间隙CQZ鹏，结果显示赂因番茄的即雏率、蒸腾速率、气孔导度均明显高于对照，而胞间隙COZ 氏于对照。

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。
