摘要

闪光燃烧作为一种种子增强技术已经显示出了希望,它可以改善体积大或形状不规则的种子材料的处理性能,这反过来又有利于大规模直接播种的后勤和生态方面。到目前为止,只有少数具有相似形态特征的草物种进行了测试。本文描述了在西澳大利亚采矿业密集的皮尔巴拉地区,闪光燃烧对19种不同旱地物种(苋菜科、菊科、藜科和禾科)的分散孔(即由种子和任何周围或附着组织组成的分散单元)的应用。对每个物种的闪光燃烧参数进行了测试,以确定并最大限度地减少体积和质量,减少颗粒凝聚力,并通过机械播种装置最大限度地提高流量,同时最大限度地提高发芽率。所有物种的燃烧导致批次体积和质量的减少,以及流动特性的改善。对于17种植物,燃烧对其发芽能力或有利或无影响。对于苋科的两个物种,用这里测试的设置燃烧导致发芽能力降低;然而,燃烧使分散剂通过机械播种装置,使机械分布是至关重要的,如果该物种要用于大规模恢复。

Flash flaming is a valid seed enhancement for a diverse range of species and seed morphologies
Flash flaming has shown promise as a seed enhancement technology that improves the handling properties of bulky or irregularly shaped seed material, which in turn benefits logistical and ecological aspects of large-scale direct seeding. To date, only a small number of grass species, that possess similar morphological characteristics, have been tested. This paper describes the application of flash flaming to diaspores (i.e. the dispersal unit comprising the seed and any surrounding or attached tissues) of 19 diverse dryland species from the Amaranthaceae, Asteraceae, Chenopodiaceae and Poaceae critical to ecological restoration in the mining intensive Pilbara region of Western Australia. Flash flaming parameters for each species were tested to identify and maximise volume and mass reduction, reduce particle cohesiveness and maximise flow through a mechanical seeding device, whilst maximising germination. Flaming of all species resulted in reductions in batch volume and mass, and improvements to flow characteristics. For 17 species, flaming either benefited or did not impact on germinability. For two species in the Amaranthaceae, flaming with the settings tested here resulted in a reduction in germinability; however, flaming enabled the diaspores to pass through a mechanical seeding device enabling mechanical distribution which is critical if the species are to be used in large scale restoration.
