“…However, these authors emphasized that the manifestation of symptoms depends on the genotype and the environment. Maia et al (2019) and Martinez et al (2020) did not observe visual symptoms in cherry tomato cultivar Sindy under omission of Ca in the nutrient solution, corroborating the result found in the present research. These authors, in turn, concluded that this cultivar studied requires a low requirement for this nutrient.…”

“…With the growing market demand for high quality products, there emerged the need to supply plants adequately with mineral nutrients, making the nutritional knowledge about the crop relevant, as it enables the analysis of morphological and anatomical aspects that are modified by changes in plant metabolism due to the specific function performed by each nutrient. Thus, experiments with omission of essential elements are used to determine the adequate mineral nutrition of cultivated plants (Flores et al, 2015;Maia et al, 2019;Martinez et al, 2020;Campos et al, 2021;Silva et al, 2021).…”

Aspects related to tomato (Solanum lycopersicum L.) mineral nutrition are important for the production of quality fruits. The cherry tomato (Solanum lycopersicum var. cerasiforme) is an alternative for most producers due to its high market value, greater productivity and good acceptance by consumers. The objective with this study was to evaluate the nutritional status of cherry tomatoes cultivated in nutrient solution under omission of macronutrients. The experiment was conducted in a completely randomized design, with seven treatments: complete nutrient solution and omissions of N, P, K, Ca, Mg and S, with five replicates. Visible symptoms of nutritional deficiency were observed in the following order of omission: at 5, 12 and 20 days after transplantation in plants under omission of N, P and K, respectively. Conversely, there were no visible symptoms of deficiency under omissions of Ca, Mg and S. The sequence of growth limitation, determined based on the shoot dry mass of cherry tomato plants, was: N>P>S>Mg>Ca>K. The omission of a nutrient, besides reducing its content in the leaf tissue, causes imbalance between the other nutrients, influencing the parameters of growth and production, leading to morphological manifestations in cherry tomato.

“…Decline in xylem functionality during fruit development have been found in many fruits such as apple (Miqueloto et al, 2014), sweet cherry (Grimm et al, 2017). Loss in xylem functionality causes calcium (Ca) deficiency, because Ca is translocated through the xylem (Martinez et al, 2020;.…”

Water movement in xylem vessel presents hydraulic system. The hydraulic system may encounter embolism (cavitation) caused by environmental stresses. Tracer dyes are distributed within the xylem and can be monitored by sectioning the tissue called dye infusion technique. The current experiment determined the optimal conditions for acid fuchsin dye infusion technique to monitor the water-conducting pathways in shoots of sweet cherry and peach trees. Shoots from 18-year-old sweet cherry cultivar 0900 Ziraat grafted onto Gisela 5 and 2-year-old peach cultivar Rich May grafted onto Garnem and GF 677 were used in the experiment. Xylem functionality and xylem water flow velocity (VXW) were evaluated by dye infusion technique. The intensity of acid fuchsin staining in the shoots increased with dye concentration. In sweet cherry trees, VXW decreased with the time course and 120 mn had the lowest VXW value. In peach, VXW of GF 677 was found further compared to Garnem. The experiment showed that the dye infusion technique is reliable for the visualization of waterconduction pathways and xylem functionality. Furthermore, the technique can be used in the studies of bud dormancy break of trees and stresses.

This study characterized growth characteristics and cellular details employing microscopy techniques in hydroponically-grown Ca2+-sufficient and Ca2+-deficient grapevines (Vitis vinifera) in a glasshouse. The Ca2+-deficient vines exhibited significant reductions in shoot length, shoot and trunk fresh weights, leaf area, chlorophyll, which eventually led to drooping, yellowing, and chlorosis of leaves. Roots were less dense and primarily dark and necrotic. Furthermore, their xylem vessels were small, polygonal, and appeared to be collapsed yet increased in number and developed lateral roots. Despite such alterations, the anatomical organization of leaves was not affected, yet they developed with more xylem vessels with thick walls and lignin in their mesophyll and vascular tissues. The chloroplasts in internodes’ chlorenchyma, phloem, and cambium underwent significant ultrastructural modifications. The concentrations of macro and micronutrients varied significantly among the roots, trunk, canes, and leaves, including the growth characteristics. These structural and growth modifications of calcium deficiency enable us to understand better the link between the symptoms and functions and for a holistic understanding of Ca2+ functionalities.
