Results show that the aqueous extract of 11 species could inhibit seed germination and seedling growth in Ligularia sagitta, and its effect is concentration dependent, increasing with the increase of concentration.

结果表明,11种供体植物水浸液对箭叶橐吾种子萌发和幼苗生长均有化感作用,不同浓度的水浸液对植物的化感作用强度不同,低浓度时较弱,高浓度时较强。

The germination patterns performed significant difference between the pre-sowing treatments for all ten Calligonum species, and the speed and per cent germination of the Calligonum species can be greatly increased by mechanical scarification or sulphuric acid treatments.

沙拐枣植物的萌发模式在不同种子预处理间均表现出明显的差异性。

The other method of germination is myceliogenic, where the sclerotium produces mycelium.

另外一种萌发方式是菌丝体遗传,在此方式中菌核产生菌丝体。

De Bary were determined by mycelial growth rate method in lab, and examed their effects on sclerotium formation and sclerotium germination.

de Bary菌丝生长的毒力,同时测定了其对菌核形成及萌发的抑制作用。

The mycelial germination of OnionBc-23 sclerotium on moisture sand surface and PDA(4℃).

灰葡萄孢属真菌菌株OnionBc-23的菌核在潮湿砂表和PDA培养基上进行菌丝型萌发(4℃)。

Cinerea were observed, and the inhibition rates could reach 100% at the concentration of 20μg/mL. The sclerotium formation, sclerotium form and distribution were influenced in different extent. C8-10 presented 90% inhibition rate on sporulation at the concentration of 40μg/mL. 1227 and C8-10 surfactants could obviously increase the permeability of cell membrane over the concentration of 20μg/mL.

两者对菌丝干重,孢子萌发均有较强的抑制作用,20μg/mL时抑制率接近或达到100%;对菌核数,菌核形态及分布有一定影响;40μg/mL C8-10对该菌产孢量的抑制率可达90%以上;1227和C8-10的浓度大于20μg/mL时均能明显影响病原菌细胞膜的通透性。

The EC50 values of procymidone and Junduqing were more than 10g/mL. At the concentration of EC50, all the tested fungicides did not affect the number of sclerotium. But the weight of sclerotium fell more than 70% after treated with triazole fungicides. All the triazole fungicides had no effect on the germination of sclerotium below the concentration of 10μg/mL.

在EC50值浓度下,所有供试药剂对菌核形成及其数量均没有影响,但三唑类杀菌剂对菌核单重影响较大,各处理所形成的菌核单重降低率均在70%以上;而当药剂浓度在10μg/mL以下时,己唑醇等三唑类杀菌剂对菌核萌发均没有影响。

Moreover, Seed dispersal also relies on animal and waterpower, which make seeds spread far distance, at the same time, the penetration of seed capsule can be improved by the dam age of animal's digestive system, so it can promote the seed germination.

此外,还有动物散布和水力作用的散布,使种子能传播较远的距离,同时种子被采食后,通过消化道的磨损使种皮的通透性提高,促进了种子的萌发

Seed coat and endosperm contained inhibitory substances, but whether it would impact seed dormancy and germination remained to be studied further.

种皮和胚乳内含有抑制物质,但是否影响种子休眠和萌发有待进一步研究。

Stramonium root, stem and leaf on seed germination and seedling growth of sesame and millet were studied.

因此,曼陀罗叶浸提液强烈抑制了芝麻和粟的种子萌发和幼苗生长,茎浸提液和根浸提液也都存在一定的抑制效应,但都弱于叶浸提液。
