“…Our result showed that the degree of juice sac granulation was positively related with leaf S (Table 9). This agrees with our previous report that S content was higher in granulated juice sacs of 'Guanximiyou' pummelo fruits than in normal ones (Wang et al, 2014). This suggests that S might play a role in the juice sac granulation of pummelo fruits.…”

“…We observed a positive relationship between leaf Cu and juice sac granulation of 'Guanximiyou' pummelo fruits (Table 9), which agrees with the reports that leaf Cu increased as the fruit granulation developed in two sweet orange cultivars (Munshi et al, 1978), and that granulated juice sacs of 'Guanximiyou' pummelo fruits had higher Cu content compared with normal ones (Wang et al, 2014). Thus, Cu might be involved in the juice sac granulation of 'Guanximiyou' pummelo fruits.…”

Three hundred and nineteen 'Guanximiyou' pummelo (Citrus grandis) orchards from Pinghe county, the southern region of Fujian province, China, were selected for this study. The objectives were to determine (i) the soil and leaf nutrient status, (ii) the relationships between leaf mineral elements and the corresponding soil elements, and (iii) the relationships between fruit quality and mineral nutrients. The results showed that soil acidification was a major problem in these orchards, with an average pH of 4.34. Soil acidification affected the availability of soil N, P, Ca, Mg, S, B, Cu and Zn and the levels of organic matter (OM) and cation exchange capacity (CEC), thus inducing soil and leaf nutrient imbalance. Indeed, severe nutrient imbalance existed in these orchard soils. 77.4% and 65.8% of soils were sub-optimum in exchangeable Mg and Ca, while 96.6% and 82.1% of soils were super-optimum in available S and P, respectively. Besides, severe nutrient deficiencies and excesses co-existed in leaves. 46.8% and 35.6% of leaves were deficient in N and Mg, while 74.8% and 70.4% of leaves were excess in B and Cu, respectively. Regressive analysis showed that leaf content of mineral elements was poorly related with the available content of the corresponding soil elements, respectively. In some orchards, severe juice sac granulation, an important factor affecting fruit quality, was observed. Regressive analysis indicated that Mg, S, Cu and Mn played a role in juice sac granulation of fruits. In conclusion, soil acidification might lead to severe soil nutrient imbalance, thus inducing leaf nutrient imbalance, eventually impairing fruit quality parameters such sac granulation.

Analysis of organic acid metabolism reveals citric acid and malic acid play major roles in determining acid quality during the development of kiwifruit (Actinidia eriantha)

BACKGROUND Actinidia eriantha is one of the most important kiwifruit species in Actinidia. The relative high accumulation of organic acids in fruit of A. eriantha is an unfavorable factor for organoleptic quality. To identify key metabolic enzymes and genes involved in organic acids accumulation during fruit development, physiological, biochemical, and molecular experiments were conducted for the dynamic fruit samples of a new kiwifruit cultivar, A. eriantha ‘Ganlv 1’. RESULTS The contents of citric acid and malic acid increased greatly during fruit development, while quinic acid content decreased obviously. Significant positive correlations were observed between fruit titratable acidity and the contents of both citric acid and malic acid, and a significant negative correlation was found between fruit titratable acidity and the quinic acid content. The high accumulation of citric acid was found to be caused by the increased activity of citrate synthase (CS), and the decreased activities of two degradation‐related enzymes, mitochondrial aconitase and nicotinamide adenine dinucleotide (NAD)‐dependent isocitrate dehydrogenase. In addition, the accumulation of malic acid depended mainly on the increased synthesis catalyzed by NAD‐dependent malate dehydrogenase (NAD‐MDH) and phosphoenolpyruvate carboxylase. Further analysis suggested that AeCS2 and AeMDH2 played pivotal roles in controlling the activities of CS and NAD‐MDH respectively. CONCLUSION The high accumulation level of citric acid relied on both the strong synthesis ability and the weak degradation ability. The accumulation level of malic acid was mainly affected by the synthesis. The novel information would be helpful for our understanding of the formation of fruit acidity quality. © 2023 Society of Chemical Industry.

Dynamics in organic acid anions were not solely controlled by a single enzyme but regulated by the integrated activity of enzymes such as nicotinamide adenine dinucleotide phosphate-malic enzyme (NADP-ME), NAD-ME, PEPC, ACO and NADP-isocitrate dehydrogenase. Sugar metabolism enzymes such as PGI, invertase and HK may play vital roles in the regulation of individual sugar metabolic processes. © 2018 Society of Chemical Industry.
