This study examined postharvest changes in “coquinho azedo” harvested at a commercially immature stage and later evaluated the quality of these fruits by comparing them with those harvested fully ripe. Fruit purchased in the 2020 harvest in Santo Antônio do Retiro, MG (Brazil), were harvested at different degrees of maturity, namely, commercially immature and ripe, according to the point of harvest adopted in the region. For 7 d, weight loss, skin color and respiratory activity were evaluated in the commercially immature-harvested fruits. At 7 d postharvest, physical and chemical evaluations of the pulp were performed. The ripe-harvested fruits were subjected to the same evaluations, but only at 1 d postharvest. The skin color of commercially immature-harvested fruits tended to yellow over the days. Respiration postharvest increased in the immature-harvested fruits. Fresh weight loss exceeded 10% but without compromising appearance. The commercially immature-harvested fruits had 55% more total phenols, whereas the ripe-harvested fruits had higher soluble solids and ascorbic acid contents. Pulp color, soluble solids/titratable acidity ratio and total carotenoid contents were similar regardless of the degree of maturity at harvest. During the days after the harvest of the commercially immature “coquinho azedo”, changes take place which cause them to resemble the fruit harvested ripe. Based on the evaluated traits, the early harvest did not compromise the ripening of the fruits.","PeriodicalId":38464,"journal":{"name":"Agronomia Colombiana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45064650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated 56 camu-camu clones distributed in three blocks with two plants per experimental plot. The variables measured were plant height (H), number of basal branches (NBB), number of terminal buds (NTB), basal stem diameter (BSD), chlorophylls a (Chl a) and b (Chl b), and total chlorophyll (Chl a + b). Principal component (PCA) and multivariate clustering analyses were performed using the average linkage mean and Mahalanobis distance algorithms. After 24 months, results showed that the characteristic that least contributed to clone selection was NBB. The plant height (H), number of terminal buds (NTB), basal stem diameter (BSD), chlorophylls a (Chl a) and b (Chl b), and total chlorophyll (Chl a + b) had the most positive contribution towards the initial selection of camu-camu clones at two years of age.

The study was carried out in two phases. In the first phase, germination was evaluated with two experiments, the first consisted of the addition of the ethanolic extract of C. lineatifolia every third day, in the second experiment the extract was only added at planting. In both cases, four concentrations of the extract (0%, 3%, 6%, and 9%) were evaluated. In the second phase, the same extracts were applied to plant leaves. C. lineatifolia extract inhibited the germination of S. oleraceus, when applied only once at sowing. As there was no germination with the extracts of C. lineatifolia, no direct inhibitory effect on the growth of the seedlings could be seen on the number of leaves, length of roots, and stem. With the foliar application, an incidence of 100% with symptoms of chlorosis and necrosis was observed using any of the concentrations evaluated, but the applications did not cause the plant death.

In this regard, several selection criteria have been put forward for sustainability assessments at the farm, regional, country, or planet levels. However, assessments at the plot or experimental unit level require, in addition to the adaptation of these criteria or the generation of new ones, the construction of a selection methodology. Thus, the aim of this study was to build a framework for selecting the minimum set of indicators that will be part of the agricultural sustainability analyses at the plot or experimental unit level. A hierarchical order of indicators was established, consisting of raw, baseline, and core indicators; the latter made up the minimum indicators set (MIS). Subsequently, selection procedures and criteria were established, consisting of mandatory, main non-mandatory, alternative non-mandatory, and correlation indicators. The selection method was evaluated with the results of a greenhouse tomato fertilization study. Of the 40 raw indicators with which the analysis began, the MIS was made up of eight core indicators: three environmental, four social, and one economic. This indicator selection method uses a rigorous process, with 22 selection criteria, distributed in four hierarchical groups. At the same time, it promotes less subjectivity, by including statistical analysis, algorithms, and mathematical processes.","PeriodicalId":38464,"journal":{"name":"Agronomia Colombiana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44908346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes to improve enzymatic activity of α-amylase and amyloglucosidase on the polymer chains of cassava starch by implementing physical and thermal pretreatments below the gelatinization temperature and before the hydrolytic process. The pretreatments increased the biocatalytic action of the enzymes, causing significant changes in the morphology of the granules, and superficial lacerations were found in samples of starches pretreated with ultrasound (UTS) or annealing and ultra-rapid freezing (ANN-C). At the structural level, the modified starches revealed substantial changes as the infrared spectra reflected a displacement of the absorption bands in the region from 900 to 1100 cm-1. This is associated with an alteration and reorganization of the amorphous and crystalline zones of the granules and is consistent with a decrease in amylose content (from 19.53% to 17.64%) and an increase in the crystallinity index. The thermal behavior of the starches was also modified by increasing the peak temperature (from 68.22°C to 75.38°C) and reducing the gelatinization enthalpy (from 19.34 to 15.79 J/g). UTS and ANN-C pretreatments significantly improved the mesoporous and hydrophilic properties of the modified cassava starches.","PeriodicalId":38464,"journal":{"name":"Agronomia Colombiana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41885636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of IHPLUS® significantly increased the percentage of germination, mainly in the first days. After 7 d, the germination rate and root and hypocotyl lengths increased in almost all treatments compared to control seedlings. The beneficial effects of IHPLUS® on the germination of P. vulgaris may be partially attributed to changes on seedling metabolism due to an increase in α-amylase activity and in the content of reducing sugars and soluble proteins.
