摘要

我们评估了钕元素（0.000、2.885、5.770 和 8.655 毫克-升-1）和锌元素（0.1、0.2 和 0.3 毫克-升-1）及其相互作用对水培莴苣植物的影响。施用 2.885 毫克钕-升-1 和 5.770 毫克钕-升-1 可增加植株高度、叶片数量和叶面积，以及新鲜和干燥茎、根和总生物量。用 2.885 毫克钕-升-1 处理的植物根系体积更大。施用 0.1 毫克锌-升-1 时，植株高度、叶面积以及新鲜茎、根和总生物量都更大，而施用 0.3 毫克锌-升-1 会增加茎和根的干生物量比率。暴露于 5.770 mg Nd - L-1 + 0.3 mg Zn - L-1 的植物叶片长度更大。经 8.655 mg - L-1 Nd + 0.3 mg Zn - L-1 处理的植物，茎和根的新鲜生物量与干生物量之比有所增加。用 20 mg Nd - L-1 + 0.1 mg Zn - L-1 处理的植物茎、根和总的干生物量重量最高。因此，钕和锌能改善植物的生长和营养状况。

Neodymium and zinc stimulate growth, biomass accumulation and nutrient uptake of lettuce plants in hydroponics

We evaluated the effects of neodymium (0.000, 2.885, 5.770 and 8.655 mg · L−1) and zinc (0.1, 0.2 and 0.3 mg · L−1), as well as their interaction on lettuce plants in hydroponics. Applications of 2.885 mg Nd · L−1 and 5.770 mg Nd · L−1 increased plant height, number of leaves and leaf area, as well as fresh and dry stem, root and total biomasses. Root volume was greater in plants treated with 2.885 mg Nd · L−1. With 0.1 mg Zn · L−1, plant height, leaf area and fresh stem, root and total biomass were greater, while applying 0.3 mg Zn · L−1 increased the ratio of dry biomass of stems and roots. Plants exposed to 5.770 mg Nd · L−1 + 0.3 mg Zn · L−1 exhibited greater leaf length. The ratios of fresh and dry biomass of stems and roots increased in plants treated with 8.655 mg · L−1 Nd + 0.3 mg Zn · L−1. Dry biomass weights of stems, roots and total were the highest in plants treated with 20 mg Nd · L−1 + 0.1 mg Zn · L−1. Nd significantly increased foliar concentration of N, P and K. Hence, Nd and Zn improve growth and nutrition.

期刊介绍： Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
