Abstract :

Background &Aims: The loss causing of pathogenic microbiological diseases during storage has a high economic impact. The research aim was to study effect of eucalyptus extract with combination calcium chloride on microflora of grapevine during storage.

Materials & Methods: Two grapevine varieties were selected for study: Alphonse Levallée and Italia. Two combinations of eucalyptus extract and calcium chloride were selected for experiment: I.1 % CaCl2 and 2% eucalyptus extract II. 2% CaCl2 and 1% eucalyptus extract III. Control-untreatment grapevine. Treatment and control both were stored storage refrigerator -POLAIR Standard (temperature-0-10C, humidity- 85-90%).

Findings: Pathogenic clear cultures were extracted from infected grapevine during storage (60-120 day). It was revealed that Botrytis cinerea and Penicilium expansum were two major infected agent which causing microbiological disease of grapevine varieties Alphonso levalee and Italia. Characterization and identification of fungi carried out using 40X-2500X professional infinity Trinocular Compoud Microscope (SKU:T690C). As a result showed the loss caused from phytopatohenic fungi were different-Control for grapevine varieties Italia with Botrytis cinerea was-55.3% and Penicilium expansum-37.6%. For Alphonso Levalée by Botrytis cinerea-54.1% and Penicilium expansum-35.2%. The best result for grapevine varieties Italia was showed 2% CaCl2 and 1% eucalyptus extract, in this case loss causing by Botrytis cinerea-42. 8%, and Penicilium expansum- 32.4%, but inhibition effect caused from Botrytis cinerea for Alphonso Levalee was-45.1% and Penicilium expansum-30.4%.

Conclusions: Thus, the combination of 2% CaCl2 and 1% eucalyptus extract had inhibition influence on developments of Botrytis cinerea and Penicilium expansum, especially on Botrytis cinerea.
