Currently, Mexico is the largest producer and consumer; however, the agronomic practices in use were established without a systematic knowledge of A. muricata L. phenology. The objective of this work then, was to conduct such a study in two of the main producing regions of Mexico: Tepic and Compostela (both in the state of Nayarit). For this, a total of 20 ungrafted trees were selected and their growth stages described using the extended BBCH-scale (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie). Overall, eight main phenological stages were identified over the course of a year. These were: the development of buds (stage 0), leaves (stage 1),and shoots (stage 3), the emergence of flowers (stage 5), flowering (stage 6), fruit development and maturity (stages 7-8), and senescence of branches (stage 9). In addition, 37 secondary growth stages were also described and quantified. The highest number of vegetative shoots occurred from March-July, 2017 and the biggest increase in floral structures from July–September, 2017. Fruit setting to physiological maturity took an average of 114 days in both Tepic and Compostela, with the most intense defoliation occurring in October, 2017 in the former (Tepic) and in December, 2016 in the latter (Compostela). Hopefully, improved agronomic practices will be established using this information, as well as suitable protocols for future physiological studies.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47532621","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}

Its short-term exposure to heat treatments can induce tolerance to this disorder; however, a short time is not enough to control the fruit fly. In this sense, the application of sequential heat treatments where the quarantine treatment is included can bring great benefits for mango marketing. The aim of this research was to evaluate the effect of two different sequentially-applied hot water treatments (HWT) on CI tolerance and changes in oxidative metabolism in mango. Mangoes were divided into four groups: control, HWT1 (dipping in water at 46.1 °C for 75 min), HWT2 (dipping in water at 55 °C for 5 min), and HWT1 + HWT2. Fruits were stored at 5 °C/30 days to induce CI and thereafter at 21 °C for 8 days. Three replicates with five repetitions were used to evaluate CI index, electrolyte leakage (EL), malondialdehyde (MDA), weight loss (WL), color, firmness and enzymatic antioxidant activity. The use of HWT1 reduced CI during low temperature storage, while HWT2 and the HWT1 + HWT2 showed lower CI symptoms during ripening. The use of HWT1 showed a similar EL % and higher MDA content (7.07 x 104 nmol·L-1) than the control (6.68 x 104 nmol·L-1). HWT1 + HWT2 showed the lowest WL (2.98 %) and the highest enzymatic antioxidant activity during cold storage and during the first days at 21 °C, while HWT2 showed the highest color and firmness retention. Hot water treatments applied sequentially can be considered an effective alternative to induce CI tolerance and to maintain the quality of mango.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48513801","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 experimental design was completely randomized with a 32 factorial arrangement and four replications. Analysis of variance and mean comparisons were performed (Tukey, P ≤ 0.05). Cl and Na concentrations in tomato leaves, stems and fruits increased significantly with increasing ratios of Cl-/anions and Na+/cations in the nutrient solution. The 75/100 Cl-/anions ratio reduced (P ≤ 0.05) the Ca concentration in leaves, while the 75/100 Na+/cations ratio decreased (P ≤ 0.05) K concentrations in leaves and stems. Both ratios reduced aerial dry biomass (48 and 25.8 %, respectively) and tomato yield (50.8 and 45.7 %, respectively). The results indicate that tomato plants grown with the 75/100 percentage ratio of Cl-/anions or the 75/100 percentage ratio of Na+/ cations absorb excessive amounts of Cl or Na, which causes ionic imbalance (especially of K+ and Ca2+) and affects dry matter production and yield.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70583462","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 effect of dill (Anethum graveolens), geranium (Pelargonium graveolens) and caraway (Cuminum cyminum) essential oils and alcohol on the vase life of Dianthus caryophyllus L. cv ‘Yellow Candy’ were investigated. Gas Chromatography/Mass Spectrometry (GC/MS) analysis of the essential oils showed that the highest percentage of essences in geranium (13.03 %), caraway (26.05 %) and dill (52.23 %) were geraniol, methyl-3-phenyl-2-propenal and linalool, respectively.

The study objectives were to evaluate the effects of paclobutrazol applications and population densities in the seedbed on the quality of seedlings to be transplanted at 60 das, and on the number of flowers and yield of plants pruned to three clusters. A randomized complete block experimental design was used with a split-plot arrangement with four replicates and 16 treatments that resulted from combining two population densities (150 and 300 seedlings∙m-2) and seven paclobutrazol treatments (one, two and three applications with 25 and 50mg∙L-1 of active ingredient), plus two controls (without application). The lower density in the seedbed resulted in lower height, larger stem diameter and higher seedling dry weight at 60 das; however, at the end of the growing cycle the number of flowers and the yield per plant were lower. Triple applications of paclobutrazol, with 25 and 50 mg∙L-1, significantly decreased height and leaf area, but dry weight and stem thickness were similar to the control. Triple application of paclobutrazol resulted in two flowers and two more fruits per plant compared to the control, possibly because the temporary arrest of vegetative growth, caused by paclobutrazol, left more photoassimilates available for the inflorescences in formation.","PeriodicalId":38261,"journal":{"name":"Revista Chapingo, Serie Horticultura","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44002550","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}
