“…Pre-harvest fruit bagging treatment is a common cultivation technique used in Japan to improve fruit quality, especially the outward appearance (Arakawa and Komori, 2006). In recent years, the usefulness of this technique has been recognized by other countries and, therefore, it has been used in commercial orchards in Australia, China, and India (Sharma et al, 2013(Sharma et al, , 2014. We also used this technique to prevent CSPD development in the 'Kurenainoyume' apple.…”

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'.

“…For example, several studies have reported that bagging could improve fruit size or weight (Kim et al 2000(Kim et al , 2003Yang et al 2009), external fruit quality (Ritenour et al 1997;Tyas et al 1998;Han et al 1999;Amarante et al 2002b;Jia et al 2005;Huang et al 2009;Wu et al 2009;Xu et al 2010;Hudina et al 2012;Sharma et al 2013), fruit firmness (Hofman et al 1997;Sharma et al 2013) and total soluble solids (TSS) content (Li et al 2006;Singh et al 2007;Wu et al 2009;Xu et al 2010;Ni et al 2011;Sharma et al 2013). Among these reports, most of them have indicated the reduction of incidence of pest infestation (Amarante et al 2002b;Teixeira et al 2011aTeixeira et al , 2011b, diseases (Kitagawa et al 1992;Hofman et al 1997;Amarante et al 2002a;Sharma et al 2013) and physiological disorders (Amarante et al 2002a(Amarante et al , 2002bTeixeira et al 2011b;Sharma et al 2013) in bagged fruits. In contrast, some studies have revealed negative effects of fruit bagging on fruit size or weight (Xu et al 2010;Hudina and Stampar 2011b), external fruit quality (Hudina and Stampar 2011b), fruit firmness Amarante et al 2002b;Singh et al 2007;Teixeira et al 2011a) and TSS c...…”

The effects of bagging on fruit characteristics and its role in physical fruit protection were investigated in three pitaya cultivars: Vietnam White (VN-White) and Chuchi Liu (Hylocereus undatus), and Chaozou 5 (Hylocereus sp.). The experiment comprised four treatments: paper-white bag (P-WB), net screen-black bag, polyethylene plasticblack bag (PP-BB), polyethylene plastic-white bag (PP-WB) and non-bagged control. Fruit bagging did not change the fruit lightness but significantly affected other peel colorimetric parameters. VN-White fruits bagged with P-WB became redder (a* ¼ 27.6), less yellow (b* ¼ 4.4) and had higher colour purity (h8 ¼ 10.7) than non-bagged fruits. Fruits with P-WB in Chuchi Liu also showed significant difference in b* and h8 values as compared with control. Bagging with PP-BB or PP-WB in Chaozou 5 also produced redder fruits (a* ¼ 31.7 and 30.3) with more colour intensity (C* 5 32.4 and 31.3) than non-bagged fruits. There were no significant differences in fruit size and weight, total soluble solids content and fruit ripening duration among treatments in all three cultivars. Fruit firmness also exhibited no significant differences among most treatments except for PP-BB, which gave a lower value than other treatments. In general, fruit bagging could reduce the peel thickness but could not increase the edible fruit rate. The most important role of fruit bagging was to effectively protect fruits from physiological factors such as cracking, bird damage and blemish, which led to the significant decrease of the total damaged and defective fruits (13.7-33.3%), as compared with non-bagged control (66.7-72.6%).

“…For example, reported that the total phenolic content in loquat was decreased by bagging treatments. In contrast, Sharma et al (2013) reported that bagged apples contained higher levels of phenolics (9.3 mg gallic/100g pulp) and exhibited higher antioxidant activity at harvest, which decreased during storage but the level was higher in bagged fruits. Consistent with our results, Awad et al (2012) reported that bagging did not affect total phenol content of "Barhee" date palm.…”

“…However, the regulatory mechanisms of such increase in vitamin C by bunch bagging remain elusive. Literature reveals that the effects of bagging on phenolic compounds of fruits have given contradictory information, which may reflect differences in cultivar, bagging material, date of bagging, period of bagging, date of bag removal and climatic conditions (Sharma et al, 2013). For example, reported that the total phenolic content in loquat was decreased by bagging treatments.…”

HE PRESENT study was conducted during the two consecutive …….seasons, 2013 and 2014 on fifteen years old "Zaghloul" date palm trees (Phoenix dactylifera L.) grown in a calcareous soil under flood irrigation system to study the effect of pre-harvest spray of the growth regulators gibberellic acid (GA 3 ) at 150 mg/l , naphthalene acetic acid (NAA) at 100 mg/l and ethrel at 1000 mg/l and bunch bagging treatments (about 4 weeks from pollination) on bunch weight, fruit physical characteristics, total soluble solids (TSS), acidity and tannins % at harvest and Rutab, weight loss, ascorbic acid, total phenol content and peroxidase activity during cold storage (0 ± 1) °C and 90-95% RH for 15 days. At harvest, all growth regulators increased bunch weight, fruit weight, fruit length and fruit diameter compared to the control except ethrel which had no influence on fruit weight as compared with the control. NAA spray gave the highest bunch weight than the other treatments. A significant increase was obtained in bunch weight and fruit physical characteristics by bunch bagging compared to un-bagged treatment. TSS % and acidity, as well as tannins, were increased by GA 3 and NAA compared with the control. Ethrel spray resulted in higher TSS content and lower acidity and tannins contents compared with control and other growth regulators. Bunch bagging decreased TSS and tannins while it had insignificant effect on acidity. During cold storage, a significant decrease in Rutab% and fruit weight loss was obtained in both seasons by all sprayed growth regulators except ethrel in the first season. Only ascorbic acid, total phenol content and peroxidase activity was significantly higher with GA 3 and NAA treatment compared with ethrel and control. In this respect, ethrel showed the lowest ascorbic acid, total phenol content and peroxidase activity among other growth regulators. The result of both seasons generally indicated that bunch bagging treatment tended to increase Rutab%, ascorbic acid and reduce peroxidase activity while it had no significant effect on weight loss and total phenol content.
