Investigation of Frost Hardiness of Some Fruit Species and Varieties Grown in Sofia Field
Keywords:
buds; frost hardiness; fruit crops; reproductive organs; temperature; varieties; vegetative organsAbstract
The study was conducted with the main country fruit species and varieties after passing the persistent frosts recorded during the winter months of years 2011/2012 are being studied five apple, 3 cherry, plum and 3 three peach cultivars. We studied the influence of low temperatures on the viability of different groups of tissues involved in the construction of wood and their influence on the reproductive organs of fruit plants vitality of vegetative and reproductive organs of these fruits. The results show that the highest percentage of frost is reported in fruiting buds, followed by the annual growth. At least damaged by low temperatures biennial wood, followed by leaf bud.
