“…Foliar application of Ca is a recommended practice for fruit crops to reduce the incidence of some Ca‐related disorders even though they have erratic effects on fruit Ca concentration and the incidence of disorders ( Rosen et al, 2006; Yamane , 2014). After reviewing the evidence for deciduous fruit trees, Yamane (2014) invoked environmental conditions, particularly relative humidity and pre‐existing within‐canopy variability in fruit Ca content as the causes of the variable response of fruit Ca concentration to foliar Ca spray. However, the penetration of exogenous calcium into fruit is also affected by the stage of fruit development.…”

Higher calcium (Ca) concentration in several fleshy fruit including kiwifruit is a pre-requisite for\ud lower incidence of Ca-related diseases and improved fruit nutritional value. This review examines\ud the internal and external factors operating along the soil-to-fruit pathway that are involved in\ud the uptake and partitioning of Ca in kiwifruit vines. After a brief description of fruit growth and the\ud dynamic of nutrient accumulation during fruit development, the review considers the role of soil\ud Ca concentration and availability, root elongation, mass flow in the apoplast, fruit transpiration,\ud competition between fruit and highly transpiring leaves, weather variables and soil moisture.\ud How fruit morphological and anatomical traits, including skin anatomy, xylem development and\ud hydraulic resistance, influence physiological processes such as transpiration and impact on Ca\ud accumulation is also discussed. The review highlights that approximately 80% of the total Ca\ud content of fruit is accumulated during the early weeks after fruit-set, suggesting that failure of\ud good fruit Ca nutrition at that time may lead to poor fruit Ca content at harvest. Therefore, based\ud on the analysis of the internal and external factors that influence Ca accumulation, recommendations\ud are made for orchard practices that maximize Ca accumulation in the kiwifruit berry, including\ud optimal pollination, nutrient and irrigation management, and manipulation of canopy architecture

“…Bitter pit is the most widespread corking disorder, and it develops before harvest and continues until storage ends (Faust and Shear, 1968). It is well known that the development of bitter pit is due to a calcium (Ca) deficiency (Yamane, 2014) and, therefore, Ca spraying effectively reduces its development (Biggs and Peck, 2015;Blanco et al, 2010;Fallahi and Eichert, 2013). Cork spot, which presents symptoms similar to those of bitter pit, is also induced by Ca deficiency and, thus, Ca spraying is a useful alleviating measure (Faust and Shear, 1968).…”

Prevention of New Cork Spot-like Physiological Disorder in ‘Kurenainoyume’ Apples by Pre-harvest Fruit Bagging

et al. 2018

'Kurenainoyume' is a new red-fleshed apple cultivar with a gradually increasing cultivation area. However, cork spot-like physiological disorder (CSPD) of the apple skin has become a serious problem over the years. Therefore, the development of strategies to reduce and prevent CSPD is strongly desired by farmers. To this end, we investigated the effectiveness of i) spraying calcium (Ca), boron (B), or both on the tree and ii) preharvest fruit bagging. Ca or B solutions or both did not decrease CSPD incidence. Furthermore, no relationship was detected between CSPD and the Ca/B content of fruit and leaves, demonstrating that the occurrence of CSPD might not be due to a deficiency in these elements. Pre-harvest fruit bagging reduced the development of CSPD depending on the light permeability of the paper bags used. Moreover, CSPD development was positively correlated with sunshine duration. Therefore, to prevent CSPD, fruit should be covered with light-impermeable paper bags at least from mid-July to late-September because the fruit covered for a shorter period developed CSPD. Thus, we propose that pre-harvest fruit bagging with light impermeable paper could be a useful and practical strategy to reduce or prevent CSPD in 'Kurenainoyume'.

Cytosolic Ca 2+ plays a key role in signal transduction in plants. Calcium imaging is the most common approach to studying dynamic changes in the cytoplasmic Ca 2+ content. Here, we used mature 'Fuji' apples (Malus pumila Mill.) to obtain viable protoplasts from flesh tissue cells by enzymatic hydrolysis; then, three small-molecule fluorescent probes (fluo-8/AM, fluo-4/AM, and rhod-2/AM) were loaded into the protoplasts. All three Ca 2+ fluorescent probes successfully entered the cytoplasm but did not enter the vacuole. Both the Ca 2+ chelator (EGTA) and Ca 2+ channel blocker (La 3+) reduced the fluorescence intensity in the cytoplasm. The calcium ionophore A23187 increased the fluorescence intensity in the cytoplasm at 5 µmol/L but decreased it at 50 µmol/L. Additionally, A23187 reversed the fluorescence intensity in the cytoplasm, which was decreased by La 3+. Ionomycin is also a calcium ionophore that can increase the fluorescence intensity of calcium in the cytoplasm. These results suggest that small-molecule Ca 2+ fluorescent probes can be used to detect changes in cytosolic calcium levels in the cells of fruit flesh tissue. In addition, the optimum concentration of fluo-8/AM was determined to be 5 µmol/L. This was the first time that protoplasts have been isolated from apple flesh tissue cells and small-molecule fluorescent probes have been used to detect calcium in the cytoplasm of flesh tissue cells. This study provides a new method to study calcium signal transduction in fruit flesh tissue.
