“…Postharvest ripening indices for kiwifruit mainly include starch degradation, cell wall metabolism, ethylene biosynthesis, and aroma generation 3 . Numerous studies have been performed to clarify the ripening mechanism of kiwifruit from different aspects, including chemical and histochemical analyses, enzyme activity changes, and gene and protein expression levels 9 – 11 . Kiwifruit is one of the high starch-containing fruits, which can degrade starch into soluble sugar after harvest 3 .…”

Kiwifruit has gained increasing attention worldwide for its unique flavor and high nutritional value. Rapid softening after harvest greatly shortens its shelf-life and reduces the commercial value. Therefore, it is imperative and urgent to identify and clarify its softening mechanism. This study aimed to analyze and compare the long noncoding RNA (lncRNA) and mRNA expression patterns in ABA-treated (ABA) and room temperature (RT)-stored fruits with those in freshly harvested fruits (CK) as control. A total of 697 differentially expressed genes (DEGs) and 81 differentially expressed lncRNAs (DELs) were identified while comparing ABA with CK, and 458 DEGs and 143 DELs were detected while comparing RT with CK. The Kyoto Encyclopedia of Genes and Genomes analysis of the identified DEGs and the target genes of DELs revealed that genes involved in starch and sucrose metabolism, brassinosteroid biosynthesis, plant hormone signal transduction, and flavonoid biosynthesis accounted for a large part. The co-localization networks, including 38 DEGs and 31 DELs in ABA vs. CK, and 25 DEGs and 25 DELs in RT vs. CK, were also performed. Genes related to fruit ripening, such as genes encoding β-galactosidase, mannan endo-1,4-β-mannosidase, pectinesterase/pectinesterase inhibitor, and NAC transcription factor, were present in the co-localization network, suggesting that lncRNAs were involved in regulating kiwifruit ripening. Notably, several ethylene biosynthesis- and signaling-related genes, including one 1-aminocyclopropane-1-carboxylic acid oxidase gene and three ethylene response factor genes, were found in the co-localization network of ABA vs. CK, suggesting that the promoting effect of ABA on ethylene biosynthesis and fruit softening might be embodied by increasing the expression of these lncRNAs. These results may help understand the regulatory mechanism of lncRNAs in ripening and ABA-induced fruit softening of kiwifruit.

“…O amadurecimento é a fase mais estudada na póscolheita, principalmente por ser nessa fase que as mudanças de composição ocorrem com mais intensidade. De acordo com Bron (2006) e Burdon et al (2016), o amadurecimento é a fase que ocorre no final do desenvolvimento e início da senescência, composta por processos que determinam as características de qualidade, evidenciadas por mudanças na composição, coloração, textura e outros atributos sensoriais. Nesse contexto, as mudanças físicas e físico-químicas durante o desenvolvimento e maturação dos órgãos vegetais são utilizadas como critérios importantes para determinar padrões de maturidade, ponto de colheita e qualidade.…”

Tropaeolum majus L. é utilizada como flor comestível e medicinal. A conservação e a qualidade das flores são determinadas, principalmente, pelo estádio de maturação em que são colhidas. O objetivo destetrabalho foi determinar o ponto de colheita de flores de T. majus. Os estádios fenológicos das flores foram determinados visualmente. A antocianina, comprimento das flores, carotenoides, flavonoides, massa fresca e teor de sólidos solúveis aumentaram durante o desenvolvimento das flores seguido de uma redução nos estádios correspondentes a senescência. O teor de ácido ascórbico decresceu durante o desenvolvimento. O estádio XII corresponde ao ponto ideal de colheita para as flores de T. majus.

“…The continuous supply of soluble carbohydrates to fruits depends on the photosynthetic activity of leaves. Soluble carbohydrates are converted into starch and subsequently degraded into soluble solids (BURDON et al, 2016). In the present study, the variation coefficient among treatments in soluble solids was 14.5%.…”

“…Fruits of treatment with 10 buds showed average of 12.4 °Brix after the storage period, being statistically superior to the other treatments. Fruits harvested with the same SS concentration may differ physiologically, resulting from starch metabolism, interfering with post-harvest fruit performance (BURDON et al, 2016). Other studies related to kiwifruit tree are necessary for the improvement of the cultural management of the plant in the edaphoclimatic conditions of Brazil.…”

Vegetative and productive behavior of kiwifruit ‘Elmwood’ submitted to pruning with different bud loading levels

The objective of this study is to evaluate the vegetative and productive behavior of kiwifruit trees cv. ‘Elmwood’ submitted to different intensities of pruning, in “Serra Gaúcha” region. Treatments consisted in maintaining different bud load levels in each cane of 10, 15 and 20 buds cane-1. The experiment, carried out during the 2016/2017 vegetative season had a completely randomized design with nine repetitions per treatment. Bud fertility, vegetative, productive and fruit quality features were evaluated. The percentage of mixed buds was higher next to the cane apex in three different treatments, while in the base of each cane ocurred the highest percentage of non sprouting buds. The decrease in the number of buds per cane induced larger leaves and increased leaf dry matter. Longitudinal and transversal diameter of fruits and fruit mass were inversely proportional to the number of buds per cane. Pruning of ‘Elmwood’ kiwifruit tree with different number of buds did not influence the index of real bud fertility, but affected directly leaf and shoot size. Pruning maintaining canes with 10 buds favors the increase of fruit weight and did not reduce productivity.
