The disease was mainly concentrated in the main fruit growing zone.at the south and southeast of Kazakhstan. Symptoms of fire blight were characteristic of two bacterial diseases: namely, necrosis, by Pseudomonas syringae Van. Hall. and fire blight by Erwinia amylovora (Burrill) Winslow et al. The authors performed bacteriological analyses to isolate and identify the causative agent of fire blight from various fruit and wild cultures of the Rosaceae family, using classical bacteriological and molecular genetic methods. Two types of bacteria were isolated from the samples affected by the disease, namely E. amylovora, the causative agent of fire blight, and P. syringae, the causative agent of bacterial necrosis. The results of the studies on the identification of bacterial species E. amylovora and P. syringae were confirmed by Swiss scientists from the Agroscope research center based on an immuno-chromatographic test and by Russian scientists at the All-Russian Research Institute of Plant Quarantine using enzyme-linked immunosorbent assay, FLASH polymerase chain reaction, and polymerase chain reaction in real-time.","PeriodicalId":402006,"journal":{"name":"Agrivita : Journal of Agricultural Science","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133178569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increment ratio of seedling height (IH), number of newly created buds (NB) during the experimental period and dry mass per plant at the end of the experiment (leaves: LM, stem and branch: SM, root: RM and total plant: TM) were compared among the treatment. The growth of clove seedlings (height < 150 cm) was generally more susceptible to water stress than to low light availability. The growth retardation by water shortage was observed in all the examined parameters except for SM. The effect of the shading treatment appeared to be limited; however, LM and NB showed significantly lower values under the heavy shade (80% shading). We concluded that dense planting of clove seedling with other competitive crops should be avoided to ensure the fast growth of clove seedlings at the establishment stage.","PeriodicalId":402006,"journal":{"name":"Agrivita : Journal of Agricultural Science","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115609820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result showed that there were significant differences (p<0.05) in the structure and composition of the MA, in terms of the total number of MA spores and the abundance of Glomus sp. under the coffee tree sampling point, while the lowest number was detected in Gigaspora sp. genera. The more intensive land management resulted in a higher abundance of MA biomass which then leads to increased soil P and uptake-P along with MA infection.","PeriodicalId":402006,"journal":{"name":"Agrivita : Journal of Agricultural Science","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131488206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine the genetic basis of immunity in 2015 – 2019, the authors performed targeted studies in the conditions of the southeast and north of Kazakhstan on the natural and the artificially infectious backgrounds of inoculation. Their scientific novelty consisted in identifying effective Sr genes of wheat resistance to the Kazakhstan population of stem rust. The obtained results of the immunological assessment of the trap varieties show that most studied genotypes with the Sr genes were susceptible to the Kazakhstan population of stem rust. With that, the varieties carrying the Sr31 gene have been affected to varying degrees. It should be especially noted that the Sr31 gene in combination with the Sr24 gene ensured more reliable protection from the population of the stem rust pathogen. The authors have selected the obtained resistance genes by their efficiency: Sr2 complex; Sr11; Sr21; Sr31; Sr36; Sr39; Sr40, SrSatu; SrNin, as well as combinations of the Sr24 and 1RS-Am genes; Sr24.31; Sr6.31.21; Sr6,24,36,1RSAm; Sr7a, Sr12, Sr6; and Sr31 absent.
