查询词典 strains

The bacteriostatic effects, action mechanisms and antimicrobial spectrum of the strains were tested. After 5 days of culture, a bacteriostatic belt of 6.9-9.67 mm in width was observed on the culture plate, and the inhibitory activity maintained for 10 d. Prefiltration fermentation of the strains P1 and P5 could significantly inhibit conidial germination of the pathogen, with inhibitive rate ranging from 97.51% to 98.12%. The action might be realized by inducing hyphal deformity, bioplasm concentration, conidial germination inhibition and distorting germ tubes of conidia.

The phytoplasmas diseases were investigated in 30 counties and cities of 10 areas in Yunnan Province. There are 12 phytoplasma diseases, including paulownia witches-broom,chinaberry witches-broom, cactus witches-broom, christmas cactus witches-broom, orange little leaf, petunia flat stem and so on were indentified using PCR with universal primers, which amplified phytoplasma 16SrRNA gene and/or ribosomal protein genes. So the kind of phytoplasma diseases in Yunnnan Province were understood. Identified the characteristic of 16SrRNA and rp gene of phytoplasma and the kind, classification and genitic relativity of these strains using RFLP, clonging and sequence analysis (nearly 20 full-length sequences of phytoplasma 16SrRNA and/or rp gene were submitted in GenBank ); The phytoplasma strains isolated from herbage plants were conserved in storeroom. 9 articles were published in the key journals of China and 1 technique invention patent was applied. The net-page about phytoplasma disease was established. 4 graduate student were bringed up.

The results showed that Hyphae, conidiophore, conidium and chlamydospore of biocontrol strains ZK7 and IPC were found in the rhizoplane, Hyphae of ZK7 and IPC penetrated epidermal cells to deep cortical cells but not in phloem tissue and xylem vessels, biocontrol strains ZK7 and IPC also crossed and even grew within epidermal and conical cell walls without any visible alterations of the plant cell.

生防菌ZK7和IPC菌株能以菌丝方式稳定定殖于烟草根表的根冠区、伸长区、根毛区、成熟区等不同部位，而在根内的定殖仅局限于根表皮层较深的细胞组织，不能侵入烟草根部的韧皮部和木质部组织。
