Evaluation of productivity and characteristics of high quality blueberries

本研究旨在阐明高品质蓝莓的生产力和特性，为开发合适的栽培方法和有效的采后技术提供良好的信息。在使用塑料薄膜的保护地栽培的情况下，目的是产生高品质的浆果，每个品种的生长受到这种栽培的不同，其自身的反应夏季修剪后收获;一些品种，如“韦茅斯”和“早期蓝色”可以被认为是适合这种栽培方法，由于其显着的旺盛的新梢生长和良好的花芽形成，但其他人不太可观。根据10多年来对兔眼蓝莓和高丛蓝莓的长期研究，对各蓝莓品种的生产力进行了评价：兔眼蓝莓品种Tifblue，高丛蓝莓品种Weymouth、Berkeley 1和Dixi在同类品种中占优势;一方面，引进品种Tifblue的生产力较低，而高丛蓝莓品种Tifblue的生产力较低;另一方面，高丛蓝莓品种Tifblue的生产力较低，而高丛蓝莓品种Tifblue的生产力较低，而高丛蓝莓品种Tifblue的生产力较低。 关于我们 从其他国家到日本的新品种也将被要求。本研究以新西兰新品种为材料，研究了不同施肥水平下的生长特性。它们是'Nui'，'Puru'和'Reka'，然后在所谓的灌溉施肥方法下种植，其中通过与滴灌系统结合来提供液体肥料。结果表明，该方法比常规固体肥处理的普如、雷卡增产2 ~ 3倍。本研究以"赫伯特“为试材，采用30μm PE膜气调包装贮藏，（聚乙烯）薄膜在4℃下，质量，总可溶性固形物，糖，与未包裹的浆果相比，花青素苷可以保持更长的时间。此外，将适口性评估为高点。在浆果花色苷糖苷中，锦葵素-3-单半乳糖苷含量最高，其次为飞燕草素-3-单阿拉伯糖苷、锦葵素-3-单葡萄糖苷、飞燕草素-3-单半乳糖苷、锦葵素-3-单阿拉伯糖苷等。通过对这些水平变化的研究，揭示了蓝莓花青苷的代谢规律，为蓝莓采后处理提供了科学依据。少

This study was carried out to elucidate the productivity and characteristics of high quality blueberries in terms of good information for developing an appropriate cultivation method and an available postharvest technology. In the case of protected cultivation using a plastic film, aiming at yielding the high quality berries, the growth of each variety subjected to this cultivation varies its own response to summer pruning after harvest ; some varieties such as 'Weymouth' and 'Early Blue' can be thought to suit this cultivation method due to their significant vigorous shoot growth and well flower bud formations, but the others are not considerable. As for the productivity for each blueberry variety, we evaluated it as follows according to the long-term research on rabbiteye blueberry and high-bush blueberry for more than 10 years : 'Tifblue' as rabbiteye blueberry, and 'Weymouth', 'Berkeley1 and 'Dixi' as highbush blueberry are predominant among the same species.On one hand, the introd … More uction of new variety from the other country to Japan would be required too. In this study the new varieties from New Zealand were investigated in order to determine the characteristics of growth behavior on different fertilizer levels. They were 'Nui', 'Puru' and 'Reka', and then grown under the method called fertigation in which they were supplied liquid fertilizer by being incorporated with a drip irrigation system. As a result, this method promoted the growth of'Puru' and 'Reka' 2 or 3 times compared with the same varieties treated with solid fertilizer as a common method. From this finding, it is possible that this fertigation method will be available for blueberry cultivation, markedly on 'Reka'.When the berries of ' Herbert' taken from either immature or mature clusters were stored by Modified Atmosphere Packaging (MAP) with a 30μm PE (polyethylene) film at 4℃, the qualities, total soluble solids, sugars, anthocyanins could be maintained for longer times comparing with the non-wrapped berries. Also, the palatability was assessed as high point. Among some anthocyanin aglycons in berry, Malvidin-3-monogalactoside was major and followed by Delphinidin-3-monoarabinoside, Malvidin-3-monoglucoside, Delphinidin-3-monogalactoside, Malvidin-3-monoarabinoside and so forth. From investigation of the change on those levels, the metabolism of anthocyanin on blueberry was found and would be available for developing an appropriate postharvest technology. Less
