“…Thus, the AVG application may reduce the red skin color, but this reduction is not significant for this 'Gala' strain. No increase in the red skin color of the fruits with the application of ethephon after AVG in the present study, which is in disagreement with prior research studies (Wang and Dilley, 2001;Steffens et al, 2006;Ban et al, 2007). Again, this result can be attributed to the high red skin coloration of this cultivar.…”

“…Its application allows for an early harvest of the fruit, and also increases the red color of fruit skin Steffens et al, 2006;Ban et al, 2007). However, ethephon application may decrease organoleptic quality and decrease the storage potential of fruit after harvest, especially in terms of declines in flesh firmness (Steffens et al, 2006;Ban et al, 2007). As well as the application of ethephon, naphthaleneacetic acid (NAA) is also used during apple production.…”

Growth regulators are used in the production of apples worldwide, especially to extend the harvest period and maintain postharvest quality. This study aimed to investigate the effects of applying aminoethoxyvinylglycine (AVG) in isolation as well as in combination with other growth regulators and postharvest techniques on the harvest quality and storage potential of 'Brookfield' apples (Malus domestica), a 'Gala' strain. Fruit receiving AVG only had the highest starch content and the highest titratable acidity at harvest. After 8 months of storage, the AVG + 1-MCP (1-methylcyclopropene) and AVG + ABS (ethylene absorption) conserved higher flesh firmness than to all the other treatments. Naphthaleneacetic acid (NAA) application induced ACC oxidase enzyme activity at harvest, but not after storage. AVG application, with or without the aid of another technique, did not decrease the red skin color of 'Brookfield' apples. Low mealiness and a high healthy fruit percentage was obtained when the fruits were submitted to pre-harvest AVG application combined with NAA, 1-MCP and ABS. Internal carbon dioxide had an inverse correlation with the quantity of healthy fruit and was directly correlated with mealiness.Keywords: Malus domestica, postharvest quality, skin color, ethephon, naphthaleneacetic acid IntroductionThe application of growth regulators is necessary either to advance or to delay the fruit harvest in the field, due to the short period that fruit remains naturally at the correct maturation stage. Besides the short harvest period, another problem is that the harvest is carried out manually and requires a lot of time and manual labor. Thus, growth regulators are frequently used in the orchards.The main growth regulator applied in the field is aminoethoxyvinylglycine (AVG) which is used to delay the harvest in order to avoid pre-harvest fruit drop (McFadyen et al., 2012;Yildiz et al., 2012). AVG blinds the active site of ACC (1-aminocyclopropane-1-carboxylate) synthase enzyme and inhibits ethylene production and maturation events initiated by this plant hormone (Yu and Yang, 1979;Huai et al., 2001). Despite the benefits promoted by AVG application, it decreases the red skin color of 'Gala' apples (Malus domestica) (Steffens et al., 2006). However, this reduction of red skin color has not yet been proven in 'Gala' mutants.Another growth regulator used extensively is ethephon, mainly to advance the fruit harvest. Its application allows for an early harvest of the fruit, and also increases the red color of fruit skin Steffens et al., 2006;Ban et al., 2007). However, ethephon application may decrease organoleptic quality and decrease the storage potential of fruit after harvest, especially in terms of declines in flesh firmness (Steffens et al., 2006;Ban et al., 2007). As well as the application of ethephon, naphthaleneacetic acid (NAA) is also used during apple production. Its application reduces pre-harvest fruit drop in apples (Yuan and Carbaugh, 2007; Unrath et al., 2009), oranges (Zur and Goren, 1977) ...

“…Ethephon is another growth regulator much used in apples production. It increases the anthocyanin content and changes fruit color of blueberry (Ban et al, 2007) and apple (Steffens et al, 2006). In some orchards, auxins are applied along with ethephon to avoid fruit drop.…”

-The objective of this work was to evaluate the effect of growth regulators on gas diffusion and on metabolism of 'Brookfield' apple, and to determine their correlation with quality characteristics of fruit stored in controlled atmosphere. A completely randomized design was used with four replicates. After eight months of storage, the effects of water (control), aminoethoxyvinylglycine (AVG), AVG + ethephon, AVG + naphthaleneacetic acid (NAA), ethephon + NAA, sole NAA, 1-MCP, ethylene absorption by potassium permanganate (ABS), AVG + ABS, and of AVG + 1-MCP -applied at different rates and periods -were evaluated on: gas diffusion rate, ethylene production, respiratory rate, internal ethylene concentration, internal CO 2 content, mealiness, and intercellular space. Fruit from the control and sole NAA treatments had the highest mealiness occurrence. Growth regulators significantly changed the gaseous diffusion through the pulp of 'Brookfield' apple, mainly in the treatment AVG + ABS, which kept the highest gas diffusion rate. NAA spraying in the field, with or without another growth regulator, increased ripening metabolism by rising ethylene production and respiration rate, and reduced gas diffusion during shelf life. AVG spraying cannot avoid the ethephon effect during the ripening process, and reduces both the internal space and mealiness incidence, but it is not able to induce ethylene production or to increase respiration rates.Index terms: Malus domestica, aminoethoxyvinylglycine, ethylene absorption, fruit quality, 1-methylcyclopropene. Efeito de reguladores de crescimento na difusão de gases e no metabolismo de maçãs 'Brookfield' em armazenamento em atmosfera controladaResumo -O objetivo deste trabalho foi avaliar o efeito de reguladores de crescimento na difusão de gases e no metabolismo de maçãs 'Brookfield', e determinar sua correlação com características dos frutos armazenados em atmosfera controlada. Utilizou-se o delineamento experimental inteiramente casualizado com quatro repetições. Após oito meses de armazenamento, os efeitos de água (controle), aminoetoxivinilglicina (AVG), AVG + ethephon, AVG + ácido naftalenoacético (ANA), ethephon + ANA, somente ANA, 1-MCP, absorção de etileno por permanganato de potássio (ABS), AVG + ABS, e de AVG + 1-MCP -aplicados em diferentes doses e épocas -foram avaliados sobre: taxa de difusão de gases, produção de etileno, taxa respiratória, concentração interna de etileno, concentração interna de CO 2 , polpa farinácea e espaço interno. Frutos dos tratamentos controle e ANA sozinha apresentaram a maior ocorrência de polpa farinácea. Os reguladores de crescimento modificaram significativamente a difusão gasosa pela polpa de maçãs 'Brookfield', principalmente no tratamento AVG + ABS, que manteve a maior taxa de difusão de gases. A aplicação de ANA no campo, com ou sem outro regulador de crescimento, acelerou o metabolismo de amadurecimento, pelo aumento na produção de etileno e na taxa respiratória, e reduziu a difusão de gases durante a vida de prateleira.

ABSTRAKCempedak (Artocarpus champeden), merupakan salah satu jenis tanaman eksotis asli Indonesia. Rasa buahnya sangat manis dan legit, aromanya sangat wangi dan khas. Buah cempedak merupakan buah klimaterik yang tingkat ketuaannya tidak seragam. Penelitian ini bertujuan untuk mendapatkan teknologi pemeraman buah cempedak yang menghasilkan kematangan buah cempedak lebih seragam dan lebih cepat tanpa harus merubah karakter fisik dan kimianya. Rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL) 1 faktor yang terdiri dari sepuluh (10) perlakuan pemeraman dengan dua ulangan. Perlakuan tersebut meliputi kontrol (tanpa perlakuan), pelukaan, karbit pada beberapa dosis 1, 2, 3, dan 4 g/kg buah (C1,C2, C3 dan C4) dan ethrel pada beberapa dosis (1000, 1500, 2000 dan 2500) ppm. Analisis statistik yang dilakukan meliputi analisis univariate dan multivariate. Hasil penelitian menunjukkan bahwa perlakuan pemeraman dengan karbit dan ethrel dapat mempercepat pematangan buah cempedak lebih cepat 3 hari dibandingkan dengan perlakuan kontrol dan pelukaan. Semakin tinggi dosis karbit dan ethrel nilai TPT dan kadar air cenderung semakin rendah, sebaliknya nilai vitamin C semakin tinggi dengan semakin tingginya dosis pada hari keempat setelah pemeraman. Perlakuan pemeraman dengan dosis karbit 2 dan 3 g/kg mempunyai kemiripan dengan perlakuan pemeraman ethrel 1500 dan 2000 ppm pada karakter total asam, vitamin C, total padatan terlarut dan kadar air setelah 7 hari pemeraman. Analisis univariate (anova) efektif dalam hal memberikan informasi mengenai perlakuan yang terbaik, sedangkan analisis multivariate (manova dan PCA) efektif dalam mengurangi/mereduksi jumlah variabel dan menentukan kemiripan suatu variabel.Kata kunci: Cempedak, Fisikokimia dan Pemeraman, Analisis Univariate, Analisis Multivariate ABSTRACT Cempedak (Artocarpus champeden), is one of the original Indonesian exotic plant species. The fruit tastes very sweet and sticky, very fragrant aroma and distinctive. Cempedak fruit is a fruit that has dissimilar maturity level. This study aimed to obtain cempedak fruit ripening technology that produces cempedak fruit's maturity to be relatively homogeneous and faster without having to change the physical and chemical characteristics. The experimental design used was a completely randomized design (CRD) 1 factor of ten (10) ripening treatment with two replications. The treatment includes a control (no treatment), wounding, carbide at a dose of 1, 2, 3, and 4 g / kg of fruit (C1, C2, C3 and C4) and Ethrel at several doses (1000, 1500, 2000 and 2500) ppm. Statistical analysis was conducted such as univariate and multivariate analyses. The results showed that treatments with calcium carbide and ethrel ripening may accelerate fruit ripening faster 3 days compared to the control treatment and wounding. The higher dose of calcium carbide and ethrel, TPT value and water content tend to be lower, whereas the higher value of vitamin C with the higher dose on the fourth day after ripening. Ripening treatment with doses o...
