TURLI DARAJADA KARTOSHKA Y VIRUSI BILAN KASALLANGAN SOLANUM NIGRUM O‘SIMLIGI BARGIDAGI XLOROFILL MIQDORINI ANIQLASH
Abstract
Ushbu maqolada kartoshka viruslari, ularning turlari, Kartoshka Y virusi (KYV) shtammlari, ularning biologik xarakteristikasi, xo‘jayin o‘simliklardagi kasallik alomatlari va ularning o‘ziga xos tomonlari, mexanik usul yordamida virus bilan turli darajada kasallangan ituzum (solanum nigrum) o‘simligi bargidagi xlorofill pigmenti miqdori, bu viruslarning o‘rganilish darajasi, tarqalishi va ahamiyati aks ettirilgan.
