Abstract:
The research approaches the problem of pathological and nonpathological degradation that occurs during storage, in apple fruit, with the
goal of finding ecological solutions to limit the losses that occur. The
methods of prevention, which include post-harvest treatments with bioactive
substances of natural origin, constitute a modern-day tendency, which is
studied in all countries with an advanced horticulture.
From a phytopathological perspective, the major cause of the
warehouse disease, including in apple fruit, is the technology applied on the
tree plantation, but also the year-specific climatic conditions.
The treatemnts were effectuated by fine pulverization on the apple
surface using a crude suspension of volatile oil from savory and swet basil,
respectvely dispersed with a special pump of Sapanish manufacturing.
Suspensions containing about 60% volatile oils were freshly extracted
from savory and sweet basil by the method of distillation through water
vapors stimulation.
To highlight the pathogen microflora of the apple fruits we examined
them carefully using a manual magnifying glass and wrote down the data
necessary to calculate the frequency of the attack, the intensity of the attack
as well as the level of damage or attack.
The statistic calculation pursued the underlining of differences
between the intensity of attack of the pathogen agents encountered on the
untreated fruits as against the variants treated demonstrating the level of
effectiveness of each treatment variant.
The volatile oils had the best effects in reducing the intensity of attack
– the percentage to which a fruit is attacked. The fruit losses due to the
diseases in the storehouse may be reduced significantly by applying these
treatments
