Abstract

The goal of the current study was to evaluate the effects of gamma ray, UV-C, UV-A (ultraviolet) treatments as seed priming on the growth, yield, quality, and the storage ability of cauliflower heads. The seeds were exposed to the following treatments: 50 and 75 kGy (gamma ray), UV-C for 15, 30, 45 minutes, and UV-A for 15, 30, 45 minutes. Plant growth and yield parameters were evaluated at the harvest time. The cauliflower heads from previous treatments were stored at 5° C for 16 days to evaluate their shelf-life traits. The results indicated that gamma ray, UV-C, and UV-A treatments enhanced the plant growth characteristics including plant height, leaf length, number of leaves, plant fresh weight, SPAD reading, and plant dry weight. Additionally, the cauliflower seeds treated with different treatments showed higher total yield, head diameter, and head weight than the control plants. The storage ability including weight loss, total soluble solids, and antioxidant capacity during refrigerated storage of cauliflower heads was not affected by the different treatments, however UVA treatment enhanced vitamin C and phenolic compounds compared to the control.

紫外线和γ射线对花椰菜穗生长、产量和贮藏能力的影响

本研究的目的是评价γ射线、UV-C、UV-A(紫外线)处理对花椰菜穗生长、产量、品质和贮藏能力的影响。将种子暴露于以下处理:50和75 kGy(伽马射线)，UV-C处理15、30、45分钟，UV-A处理15、30、45分钟。在收获时评估植株生长和产量参数。将先前处理的花椰菜头在5°C下保存16天，以评估其货架期特性。结果表明，γ射线、UV-C和UV-A处理均能提高植株的生长特征，包括株高、叶长、叶数、植株鲜重、SPAD读数和植株干重。此外，不同处理的花椰菜种子的总产量、穗粗和穗重均高于对照植株。不同处理对花椰菜头在冷藏过程中的失重、可溶性固形物总量和抗氧化能力没有影响，但与对照组相比，UVA处理提高了花椰菜头的维生素C和酚类化合物含量。

期刊介绍： Notulae Botanicae Horti Agrobotanici Cluj-Napoca is a peer-reviewed biannual journal aimed at disseminating significant research and original papers, critical reviews and short reviews. The subjects refer on plant biodiversity, genetics and plant breeding, development of new methodologies that can be of interest to a wide audience of plant scientists in all areas of plant biology, agriculture, horticulture and forestry. The journal encourages authors to frame their research questions and discuss their results in terms of the major questions of plant sciences, thereby maximizing the impact and value of their research, and thus in favor of spreading their studies outcome. The papers must be of potential interest to a significant number of scientists and, if specific to a local situation, must be relevant to a wide body of knowledge in life sciences. Articles should make a significant contribution to the advancement of knowledge or toward a better understanding of existing biological and agricultural concepts. An international Editorial Board advises the journal. The total content of the journal may be used for educational, non-profit purposes without regard to copyright. The distribution of the material is encouraged with the condition that the authors and the source (Notulae Botanicae Horti Agrobotanici Cluj-Napoca or JCR abbrev. title Not Bot Horti Agrobo) are mentioned.
