Study of the cuttings of grapes

Grapes are used by man since ancient times. The first varieties came from the wild plants V. vinifera. Varieties of grapes are valued for berries, which have dietary and medicinal properties. Rooting cuttings of grapes ranged from 21.5 to 92.1%. The main influence on the percentage of rooting was exerted by the factor of varietal specificity. The correlation coefficient between the values of the cuttings during the years of the studies amounted to r=0,65, that is, the trend of rooting of cuttings of different varieties stored in the different years.
