STUDY SPREADING AND PLANTS RESERVEYTION OF PVX AND PVL WITH METHOD ENZIM-LINKED IMMUNOSORBENT ASSAYS
This thesis indicates the spreading degree and reservator plants of potato viruses X and L in Taylak and Jomboy regions of Samarkand. The spreading degree and reservator plants of potato viruses have been revealed by collected samples of plants (leaf, stem, root) were investigated in «sandwich» versions of method Enzim-linked immunosorbent essays in laboratory. First research on basis of collected plants from 4 farms in Taylak, which involved total 10,5 hectare area, the spreading rate of X virus of potato was 25.15?%. On the other hand, the rate of L virus was higher than by 81,62?%. In the second years researchs on the samples were collected from 23,5 hectare areas on 4 farms indicated that, the spreading rate of X virus of potato was 31,37?%, but the spreading rate of L virus declined by, 40,07?%. Initial researches samples were collected from 4 farms in Jomboy region involved 10,2 hectare areas showed that, the rate of X virus was 26,57?%, the rate of L virus was 65,35?%. The second survey samples were collected from 8,1 hectare, according to the result of Enzim-linked immunosorbent essays , it was obvious the spreading degree of X virus was 6,35?%, the degree of L virus 13,75?%. In the result of surveys some some reservator plants of viruses were indicated, such as Cucumis sativus L., Rumex crispus L., Brassica juncea (L) Czern, Althae officinalic L., Malva neglecta Wall for X viruses, Lucopersicum esculentum Mill, Abutilon theophrasti Medic for L virus.
