“…Nevertheless, further studies should address this response to better understand the significance of such a change from the perspective of plant performance. In general, the anatomical characteristics of plants described herein match those of plants adapted to greater light intensity and greater efficiency in water use [40,41]. It should be noted that the cultivars showed similar growth performance despite the different anatomical arrangements influenced by Trichoderma species.…”

“…Soybean cultivars grown under the same environmental conditions reacted differently to the PLOS ONE treatments with the fungi, with the NA 5909 RG cultivar most responsive to the presence of T. harzianum, in terms of stomatal density. As is true for rice plants [33], increased stomatal density is a desirable anatomical feature in plants that may perform better under stressful conditions such as increased light irradiance and lack of water; this characteristic is observed for other drought-resistant plants [36][37][38][39][40]. Additionally, Trichoderma spp.…”

“…Further evidence to support this hypothesis is observed in NA 5909 RG treated with T. asperellum, which showed increased thickness of the mesophyll and of the spongy parenchyma, a factor that directly relates to the photosynthetic apparatus of the plants, and has been shown to respond to different environmental conditions [8,33]. On the other hand, the BRSGO Caiaponia cultivar treated with T. harzianum showed an increased diameter in vessel elements in the xylem of roots, which increases their capacity for water uptake and transportation [39,40], and is thus a desirable anatomical feature that is likely of adaptive importance to the plants. BRSGO Caiaponia reacted negatively to the presence of Trichoderma spp.…”

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.

“…Yellow passion fruit plants do not tolerate waterlogging for more than four days, which especially affects roots and stem growth (Basso et al, 2019). As shown in Table 3, flooded yellow passion fruits increase the relative water content, but the photosynthetic and transpiration rates decrease, along with the stomatal conductance (Govêa et al, 2018;Faria et al, 2020). Nonetheless, because of the formation of an aerenchyma in the cortex of flooded plants (Govêa et al, 2018), passion fruits have mechanisms of adaptation to higher humidity conditions in the root environment for a time; thus, Faria et al…”

The development of Andean fruit crops is viewed as an important and healthy contribution to global food consumption but ecophysiological studies on these fruit trees are scarce. 96% of approximately 520 Passiflora L. species are distributed in the Americas, especially in Colombia and Brazil. Many of these species originated on the edges of humid forests in tropical valleys. The four species: yellow passion fruit (Passiflora edulis f. flavicarpa Degener), sweet granadilla (Passiflora ligularis Juss.), purple passion fruit (Passiflora edulis f. edulis Sims) and banana passion fruit (Passiflora tripartita var. mollissima (Kunth) Holm-Niels & P.M. Jørg) are widely cultivated in Colombia, and their ecophysiological findings are described in this review. The demands, in terms of temperature (°C) and altitude (masl) are, for yellow passion fruits: 15-28 °C and 0-1,300 masl; sweet granadillas: 15-23 °C and 1,800-2,600 masl; purple passion fruits: 15-22/12-14 °C (day/night) and 1,600-2,300 masl; and banana passion fruit: 13-16 °C and 1.800-3.200 masl; all of them have high requirements for solar radiation, a minimum of 7 h of sunshine per day, to encourage flowering and fruit quality. Cloudy days decrease growth, flower bud induction and flower opening. Temperature and photosynthetic active radiation are the climatic factors that have the greatest effect on plant development. Relative humidity between 60 and 80% supports effective pollination and fecundation. Passiflora L. crops do not support long periods of waterlogging, with a maximum of 4 days for yellow passion fruit. Climatic events such as prolonged rain, intense droughts, strong winds and hail are harmful for these plants.

“…Caso as mudas de jabuticabeira tivessem sofrido efeitos do alagamento, estas teriam a produção de compostos fenólicos aumentado em virtude dos metabólitos secundários que seriam expressos mais ou menos em relação ao nível de estresse sofrido, agindo como defesa vegetal. Govêa et al (2018), ao avaliarem o teor de prolina em mudas de maracujazeiro submetida ao solo em capacidade de campo, pré-submergido e alagado, verificaram teores entre 0,04, 0,02 e 0,04 µmol prolina g -1 de material fresco, respectivamente.…”

O objetivo deste trabalho foi avaliar o estresse hídrico em mudas de jabuticabeira por meio da inundação das plantas por diferentes períodos e lâminas de água. Dois experimentos com mudas de jabuticabeira foram instalados, no primeiro as mudas com 18 meses foram submetidas a lâmina de água de cinco centímetros, por um período de 0, 3, 5, 10 e 15 dias ou por dois períodos de 3, 5, 10 e 15 dias após intervalo de 30 dias. No segundo experimento, as mudas com 24 meses, foram inundadas por água até altura do colo, por períodos de 0, 5, 10 e 15 dias, ou por dois períodos de 5, 10 e 15 dias após intervalo de 30 dias. Tais condições visam representar estresse hídrico por inundação. Sendo avaliadas variáveis biométricas como, número de folhas, diâmetro do caule, tamanho total, massa seca das raízes e da parte aérea e massa da matéria seca total. As determinações fisiológicas foram teor de clorofila total e rendimento quântico. As variáveis bioquímicas foram teor de proteínas, teor de açúcares totais, fenóis totais e prolina. O crescimento das mudas de jabuticabeira não foi afetado pelos períodos de inundação adotados para os experimentos com diferentes capacidades de campo. Nos tratamentos em que as plantas foram submetidas aos dois ciclos de inundação com lâmina de água a altura do colo apresentaram diferenças significativas no incremento em número de folhas, altura da muda e diâmetro do caule o que consequentemente alterou a massa seca da parte aérea.
