Papaya (Carica papaya L.) stands out as a strong economic driver, being one of the fruit trees that most contribute to the total volume of brazilian production. The description of leaf characteristics allows to understand structures that act in resistance to pathogens, relationships with water resources and photosynthetic of plants, in addition to contributing to genetic improvement programs. However, there are few studies that attempt to describe the leaf anatomy of the different papaya cultivars. Thus, this study aims to describe the main leaf structure of papaya cultivars Sunrise Solo and Golden THB. The leaves were collected in the municipalities of São Mateus and Aracruz, located in the north of the State of Espírito Santo, using transversal and paradermic sections and the usual techniques of plant histology. Both cultivars presented uni-stratified epidermis, followed by palisade chlorophyll parenchyma and lacunous with collateral vascular system. Calcium oxalate druses were more observed in the Sunrise Soil cultivar. The differences between cultivars were in the number of layers of mesophyll tissues.

“…Trichomes play important roles in the context of plant ecology, and aspects related to their distribution and content may influence plant adaptability to a great extent. There are several functions of trichomes in plants, and tector trichomes can prevent undue loss of water [29,30]. Another possible function, that of the cover trichomes, is in defense against pathogens [31,32].…”

Anatomical changes induced by isolates of Trichoderma spp. in soybean plants

In the current work we evaluated the anatomical changes induced by T. harzianum and T. asperellum in two soybean cultivars, BRSGO Caiaponia and NA 5909 RG. Soybean production represents a growing market worldwide, and new methods aimed at increasing its productivity and yield are constantly being sought. Fungi of the genus Trichoderma have been widely used in agriculture as a promising alternative for the promotion of plant growth and for biological control of various pathogens. It is known that Trichoderma spp. colonize plant roots, but the anatomical changes that this fungus can cause are still less studied. Experiment was conducted in a greenhouse to collect leaves and soybean roots to perform analysis of growth parameters, enzymatic activity of defense-related enzymes and anatomical changes. It was observed that inoculation of Trichoderma spp. caused anatomical alterations, among them, increase in stomatal index at the abaxial leaf surface, thickness of the root cortex, thickness of adaxial epidermis, mean diameter of the vascular cylinder, thickness of the mesophyll, and thickness of the spongy parenchyma of the soybean plants. These results indicate that the alterations in these factors may be related to the process of plant resistance to pathogens, and better performance against adverse conditions. This study demonstrates that the anatomical study of plants is an important tool to show the effects that are induced by biological control agents.

“…The benign climate in tropical areas permits papaya planting all throughout the year, allowing continuous fruit production [5]. In Europe, only a few areas present the climate required to produce papaya, and, where possible, protected cultivation is almost mandatory [6,7].…”

Determination of the Best Planting Season for the Protected Cultivation of Papaya

Papaya is a tropical crop increasingly cultivated in the greenhouses of subtropical regions such as South East Spain, where the determination of the best planting season is important to ensure a stable fruit production and quality during the year. In this work, we studied plant growth, yield, and fruit quality, comparing spring and autumn planting seasons in ‘Intenzza’ cultivar. The results showed that planting in spring favors plant growth, leading to an earlier entry into production. Total yield and fruit quality were similar in both planting seasons, although the spring cycle provided higher profits due to greater commercial yield and lower discards. Our results confirm that adverse environmental conditions affect the crop in a similar way regardless of the planting season, so different growing cycles are not very useful for filling the production gaps and fighting against seasonality in our region, unless unfavorable climate conditions are avoided inside the greenhouse.
