Biological control using antagonistic microorganisms has been the subject of increased interest for postharvest pathogen control. Gray mold is an important factor in the perishability of strawberry fruit, both pre- and postharvest. In view of the specific characteristics of this host–pathogen interaction, strawberry fruit represent a suitable commodity with which to investigate the efficacy of alternative control, including the use of biological measures. During 1994 and 1995, ripe strawberry fruit were harvested from local plantings and endemic microflora were analyzed for potential antagonist modes of action toward B. cinerea. Two bacteria were isolated and these, along with other bacteria and yeast obtained from other sources, were used to inoculate strawberry fruit stored at different temperatures. Effects of storage temperature and interactions of pathogen/antagonist and fruit quality were determined. The results illustrate the potential of using yeast at low temperatures and bacteria at higher, ambient conditions to achieve effective postharvest control of B. cinerea. Microorganisms derived from the fruit and of presumably local origin exhibited significant biocontrol effects and showed a higher capacity for adaptation to the handling practices of strawberry fruit, especially at lower storage temperatures.

The research on grafting in horticultural plants has increased in recent years due to the benefits of grafting on disease control, productivity, and fruit quality. This study analyzes the scientific production on grafting in horticultural plants, using bibliometric techniques with the objective of obtaining a vision of the characteristics of the work carried out in the world on this subject. The worldwide evolution of research in this field was analyzed from 1979 to 2018 using a bibliometric analysis of 1376 articles. The analysis provided evidence of scientific production of authors, institutions, and countries. The results showed a growing interest on grafting in horticultural plants, mainly in the past decade when 73% of the total analyzed articles were published. The most productive subject area was Agricultural and Biological. The most productive journal was Scientia Horticulturae, and the one that obtained highest number of citations was Plant Physiology. The most cited authors per article were Colla, Roupahel, and Cardarelli. The most prolific institution was Agricultural Research Organization of Israel. China, United States, and Spain were the countries that published the most articles. The countries with the highest percentage of international collaboration were Germany and United Kingdom.
