Potato virus X eradication in cultured potato meristem tips

Short Communication


Potato virus X (PVX) infectivity of three series of axillary potato meristem tips, each including the apical dome plus one, two and four leaflets respectively, was compared statistically with the infectivity of three series of plantlets developed from meristem tips of corresponding sizes, cultured in vitro. PVX eradication depends on the size of meristem tips. The difference between the percentage of PVX-infected plantlets and the percentage of PVX-infected meristem tips was found statistically significant when one and two leaflet meristem tips were considered. This result gives experimental evidence of an active role of meristem tips development in the virus eradication process.
