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 ...

The results showed that Sigma Broad had a good control of Veronica didyma, Avena fatra, Vicia sativa, Galium aparine.and Rorippa indica., more significant in term of fresh weight control and the inhibition rate of weed height despite less weed control in term of plant number,which maintained a certain number of weeds,due to delayed use.

结果表明，阔世玛对小麦田婆婆纳、野燕麦、大巢菜、猪殃殃、野油菜等单双子叶杂草有较好的防除效果，春季晚用，对杂草的密度防效不佳，小麦田间保留了一定数量的杂草，但对杂草的鲜重防效、株高抑制率显著。

Water stress experiments on Caryopteris mongholica Bunge of six provenances were conducted under three intensities selected by the provenance environments: mild, moderate and severe, of which the soil moisture were 80～85%, 45～50% and 15～20% of the field capacity respectively.

中文摘要：以6个种源的1年生蒙古莸为试验材料，采用称重控水的方法，根据种源地的情况设置充足水分、中度胁迫、重度胁迫3个水分梯度，分别维持在田间持水量的80～85%、45～50%、15～20%开展水分胁迫试验。

Field experiments were conducted to examine integrated inhibition of allelopathic rice (Huakangcao 78), bensulfuron methyl application and water management on weeds in paddy field, with the purposes of attempting to reduce the dosage of herbicide applied in rice field and exploring new ways of weed management in rice production. The results showed that allelopathic rice could inhibit the germination and growth of barnyardgrass Echinochloa crusgalli L.

Some field samples of Solanaceae collected from Zhejiang and Shanxi Provinces were detected by DAS-ELISA and biological tests, results showed that ToMV was a common pathogen of tomato and eggplant. About 50%of detected Solanum melongena samples had ToMV both in Zhejiang and Shanxi provinces.However,there was a significant difference between tomato samples from Zhejiang and Shanxi provinces.In Zhejiang province, only about 10%of samples were infected by ToMV, while the numbers of infected samples were above 60%in Shanxi.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
