Abstract

The stability of the flower stem, large bud size, and desirable postharvest life are key characteristics of high-quality roses, directly influenced by calcium content. This study introduces novel insights into the synergistic effects of calcium fertilizers—calcium amino acid chelates and calcium silicate—compared with calcium nitrate, a common fertilizer, on flower quality, antioxidant enzyme activity, nutritional value, and postharvest life of two grafted rose (Rosa hybrida L.) cultivars (‘Samurai’ and ‘Jumilia’). Nutrient solutions containing calcium nitrate, calcium- glycine chelates and calcium silicate were prepared with control treatment compromising 10% of the calcium fertilizer requirement. Calcium silicate uniqly improved root length and volume, root potassium and phosphorous concentrations in “Samurai” cultivar and root iron and leaf magnesium in “Jumilia” cultivar, contributing to increased structural stability and extended postharvest performance. Calcium nitrate significantly increased leaf and root nitrogen concentrations and total root protein in “Samurai” cultivar. Calcium concentrations of root in “Jumilia” cultivar, leaf and petal in “Samurai” cultivar were significantly higher with the application of the calcium-glycine chelate. Calcium-glycine chelate improved leaf calcium and photosynthetic rate in “Samurai” cultivar. Moreover, calcium-glycine chelate significantly enhanced antioxidant enzyme activity (CAT, POD, SOD), which plays a crucial role in delaying senescence and extending vase life. This resulted in a minimum relative percentage reduction in the fresh weight. These findings suggest that novel calcium formulations can effectively improve the commercial quality and longevity of roses in hydroponic systems, offering both economic and environmental benefits.

水培条件下蔷薇品种对不同来源钙肥的形态化学响应

花茎稳定、花蕾大、采后寿命长是优质玫瑰的关键特征，这些特征直接受钙含量的影响。本研究介绍了钙肥料（氨基酸螯合钙和硅酸钙）与硝酸钙（一种普通肥料）对两种嫁接玫瑰（Rosa hybrida L.）品种（“武士”和“Jumilia”）的花品质、抗氧化酶活性、营养价值和采后寿命的协同效应的新见解。配制了含硝酸钙、甘氨酸螯合钙和硅酸钙的营养液，对照处理降低了10%的钙肥需要量。硅酸钙能显著提高“武士”品种的根长和根体积、根钾和根磷浓度以及“Jumilia”品种的根铁和叶镁含量，有助于提高结构稳定性和延长采后性能。硝酸钙显著提高了“武士”品种叶片和根系氮浓度以及根系总蛋白含量。甘氨酸钙螯合剂的施用显著提高了“Jumilia”品种根系、“Samurai”品种叶片和花瓣的钙浓度。甘氨酸螯合钙提高了“武士”品种叶片钙含量和光合速率。此外，甘氨酸螯合钙显著提高了抗氧化酶（CAT、POD、SOD）活性，对延缓衰老、延长花瓶寿命具有重要作用。这导致了鲜重的最小相对百分比减少。这些发现表明，新型钙制剂可以有效提高水培系统中玫瑰的商业品质和寿命，具有经济和环境效益。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
