Distinctive feeding damage caused by adults is often the first indicator of CRB activity in a new location. Multiple approaches to damage assessment have been used, reflecting observers’ experience. The lack of standardisation makes it difficult to compare CRB impacts on coconut palms over time. We examine damage assessment from three perspectives: participants, power and purpose. Participants applied binary, 3-point and 5-point damage scales consecutively to photographs of damaged palms. Participant responses were more accurate using the binary scale compared with the 5-point scale. Experience with CRB improved accuracy, but this did not wholly compensate for the effect of scale complexity. Calculations of statistical power determined minimum sample sizes to detect a 20% change in palm damage was 50 palms for the binary scale, 150 palms for the 3-point scale and > 200 palms for the 5-point scale, when the change in damage was spread across damage categories. More complex damage scales did not increase the likelihood of detecting significant changes in palm damage. With real-world examples, including detecting new outbreaks and managing established populations, recommendations were developed to standardise damage assessment for CRB on coconut palms.","PeriodicalId":19297,"journal":{"name":"New Zealand Journal of Crop and Horticultural Science","volume":"56 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136349039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Enhancement of capsicum ( <i>Capsicum annuum</i> L.) functional food value through nutrient supplementation with a biostimulant complex comprising triacontanol, phosphate, and potassium","authors":"Kimber Wise, Jamie Selby-Pham, Tomer Simovich, Harsharn Gill","doi":"10.1080/01140671.2023.2278799","DOIUrl":"https://doi.org/10.1080/01140671.2023.2278799","url":null,"abstract":"ABSTRACTCapsicum (Capsicum annuum L.) is a popular fruit (culinary vegetable) which is consumed for its flavour and functional food potential, associated with the abundance of antioxidant phytochemicals present such as phenolics and flavonoids. This study aimed to explore the impacts to capsicum growth and functional food value from supplementation with a biostimulant complex (TRIA-PK) comprising triacontanol (TRIA), phosphorous (P), and potassium (K). Plants were grown hydroponically under controlled conditions wherein TRIA-PK was provided to treatment plants within the liquid nutrient solution. Ripe fruits were sampled and compared for impacts to yield, quality, and functional food measures. Application of TRIA-PK significantly increased total phenolics (p = 0.014), flavonoids (p = 0.003), and peroxidase activity (p = 0.030), which reflect increased functional antioxidant activity within fruits. Of note, this increased functional food value also aligned with a 9-day reduction in median harvest timing (p < 0.001) and did not come at the cost of plant yield, with no statistically significant differences between treatments. These results provide valuable information to capsicum farmers, highlighting that supplementation of fertiliser solutions with a TRIA-PK complex is a potential strategy for enhancing the functional food value of capsicum for consumers.KEYWORDS: Hydroponicsbell pepperantioxidantsuperfoodphenolicsflavonoids AcknowledgementsThe authors would also like to acknowledge Nutrified Pty Ltd for the industry scholarship which supported this work.Author contributionsKW carried out experiments, constructed figures, and drafted the manuscript.

Thus, they exhibit low precision when they are used in regions with mild winters. However, there are several little-known models that are more precise. This study aimed at evaluating the precision of eight different estimation models of chill accumulation applied to five apple cultivars which were grafted on two distinct rootstocks in a region with mild winters. Based on the coefficient of variation, the Microsoft Excel® program was used for evaluating the precision of the following models: Utah, modified Utah, CH < 7.2°C, CH < 10°C, CH < 15°C, Low chill, Taiwan low chill and Daily positive Utah chill unit (PCU). The lowest precision was attributed to both models Utah and CH < 7.2°C (the most common model in Brazil). Models CH < 15°C, Taiwan low chill, Low chill and modified Utah were considered precise (coefficient of variation  < 15% in annual chill accumulation and to evaluate requirement to overcome dormancy in cultivars). No important differences were observed in models precision between ‘M-26’ and ‘M-9’ rootstocks.","PeriodicalId":19297,"journal":{"name":"New Zealand Journal of Crop and Horticultural Science","volume":"51 1","pages":"420 - 431"},"PeriodicalIF":1.3,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46875318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
