Effect of Various Stains on The Stability And Particle Length Distribution of Three Poty VirusesS KManoharauthorRRajeshwariauthorFour negative stains were tested on Peanut mottle virus (PMV), two irolater of Peanut green mosaic virus-systemic necrosis (PGMV-SN) ar~dsy etrmic mosaic (PGM V-SM), to datrrmlne their effects on the stability and particle length distribution. Whan phosphotunngstate(PleTA ) at pH 7.0 was used, particle lengh and width of PMV and PGMV-SM werr conside~ably affecrnd rasulting in variation, whereas PGMV-SN war la18 affected. When uranyl acotete (UA) and urrnyl formate (UF) ware ured, tho prrlicler of PGMV-SM and PMV were better preserved, in contrast to PGMV-SN which was unstable in both the uranyl stains. PGMV.SN was well presarved in ammonium molybdrte (AM) o f pHs 3.5 and 6.5 but was d;sruoted in OH 8.0. Although PMV could be stairled with AM of pH 3.6, particles ware poorly stained In wM ot pHs 6.6 and 8.0. Pertlcles ol PGMV-SM were poorly strined in AM of all the three pH valuer.Plant VirologyFertilizer Applications1985Indian Virological SocietyArticle
