“…Previous studies used foliar nutrition with different mineral elements-mainly B, Ca, Mg, K, or Zn, among others-and the application of all these elements reduced the cracking in different fruits [17,19,25,26]. In our experiment, we applied Ca alone or combined with the rest of the elements, as well as a separate nutrient treatment without Ca.…”

“…In addition to Ca, many other elements have been associated with improvement of the cracking resistance and firmness of fruits, the most important being boron (B), magnesium (Mg), potassium (K), and zinc (Zn). These are mainly associated with improvement of the cell membrane, cell walls, or cuticles, through modification of the expression of genes or a merely structural function [17,19,25,26].…”

Fruit cracking affects many types of crops and is a major problem since the breakage of the surface of the fruit produces high economic losses. Numerous studies have looked at different ways to prevent this, mainly in melon, but with a low success rate. In this work, a standardisation of the induction of cracking is proposed that involves changes in the irrigation pattern (high conductivity or double irrigation). The prevention of the appearance of cracking was carried out through different foliar mineral treatments. The incidence of cracking was studied in relation to gas exchange variables and the concentrations of minerals in tissues. Our results show a more pronounced increase in cracking with double irrigation. Multiple elements were found to be associated with cracking such as B, Ca, K, Mg, Mn, Na, P, and Zn. Furthermore, foliar application of different microelements (B, Cu, Fe, Mn, Mo, and Zn) decreased the melon cracking incidence, thus assigning to the appropriate combination of these elements a crucial role in cracking amelioration.

“…In this research, we found that leaf content of P, K, and B were not significantly different among treatments, and it was supported by Morgan et al (2005) who reported that there was no correlation between N or P concentrations in leaf or peel and the peel thickness. Hardiyanto & Devy (2019) also mentioned that nutrient levels in the leave was not correlated with a nutrient level in the fruit peel. Additionally, Hosseinifard & Panahi (2006) also confirmed that a negative correlation was shown between the percentage of K and Ca in the leaf of Pistachio.…”

The fruit peel anatomy, leaf nutrient content, and fruit quality of ‘Terigas’ mandarin in relation to fruit cracking

et al. 2023

‘Terigas’ mandarin is one of the cultivars cultivated in almost all of Indonesia’s provinces. However, this cultivar is prone to cracking, and little research has been conducted on fruit cracking in Indonesia. The goal of this study was to determine the effect of fruit cracking on peel anatomy, leaf nutrient content, and fruit quality in ‘Terigas’ cultivar. A Completely Block Design (CBD) with three replications was used. Results showed that the peel thickness of uncracked with big fruit size was significantly the highest, while epidermis of cracked fruit with big size was the thickest. The largest oil glands size was shown in uncracked fruit with a big size. The leaf that supported uncracked fruit with a big size had the highest Ca content, whereas the lowest Ca content was observed in the leaf that supported cracked fruit with a small size. In contrast, the leaf that supported cracked with a small fruit size had the highest Zn content. Regardless of fruit size, fruit weight, fruit diameter, and pH of uncracked fruit were significantly much higher than cracked ones. Nevertheless, the Total Soluble Acid and vitamin C of cracked fruit were significantly higher than uncracked ones. This study may provide the important keys to the fruit cracking effect, and as a tool to lessen citrus fruit cracking, especially in ‘Terigas’ mandari

Causes of fruit cracking in the era of climate change. A review

2021

View full text Add to dashboard Cite

The objective of this review was to report on advances in environmental, cultural, and physiological aspects of fleshy fruit cracking to reduce or avoid this disorder, which affects many fruit species. Cracking is a physiological disorder that limits the production and quality of fleshy fruits because it affects the exocarp and mesocarp, especially with climate change and variability. Fruit cracking is generated by external factors (agronomic and environmental) and internal factors, several of which require exhaustive study. The incidence of cracking varies widely according to climatic characteristics during fruit development, different fruit species and varieties, growth sites, and crop management. This physiological disorder is aggravated by increases in rain intensity, especially after a dry season or in areas with increased temperatures. Knowledge on causes of cracking has generated management strategies that involve genetic improvement, ecophysiological conditions, agronomic practices such as pruning, irrigation, and fertilization (mainly with Ca, Mg, B, and K), applications of plant growth regulators, and use of plastic covers, etc. For several fruit trees, these strategies are effective, but in species such as the cape gooseberry, cracking remains without a full explanation or effective management.
