Embryo length, radicle emergence and shoot emergence were analysed to determine the level of morphophysiological dormancy (MPD) of seeds. Mean embryo length in fresh seeds was 1.30\u00a0mm, and required growth to at least 2.51\u00a0mm to germinate. The critical embryo length was 4.1\u00a0mm. In the laboratory, the embryo reached 3\u00a0mm length after 20 weeks of warm-temperature incubation (20\/7 or 25\/10\u00b0C), which in fact represents a combination of warm + cold stratification. In seeds subjected to cold stratification (1.5 or 5\u00b0C) for 24 weeks, embryos hardly grew. Gibberellic acid stimulated embryo growth and germination. In the outdoor phenology test, the embryos grew from 1.30\u00a0mm, i.e. fresh seeds sown in September, to 2.98\u00a0mm at the end of the following March. In the \u2018move-along\u2019 test (laboratory), starting with temperatures of warm stratification [i.e. 25\/10\u00b0C (4 weeks) \u2192\u00a0 20\/7\u00b0C (4 weeks) \u2192\u00a0 15\/4\u00b0C (4 weeks) \u2192\u00a0 5\u00b0C (12 weeks) \u2192\u00a0 15\/4\u00b0C (4 weeks)], and in the outdoor phenology study on seeds exposed to a similar temperature sequence, radicle emergence percentages reached 73% after 28 and 35 weeks, respectively. <em>V. lantana<\/em> does not exhibit a delay between root and shoot emergence, dismissing any kind of epicotyl dormancy. Seeds of <em>V. lantana<\/em> have non-deep simple MPD, a level not detected previously in the genus <em>Viburnum<\/em>, with the physiological dormancy component overcome by a combination of warm and cold stratification, preferably in that order.<\/p>\n<p class=\"section-title\"><strong>Keywords:\u00a0<\/strong>Caprifoliaceae,\u00a0epicotyl dormancy,\u00a0seed dormancy, <em>Viburnum lantana.<\/em><\/p>\n<\/div>\n\n<div id=\"cmsms_button_69d9506eabb9d\" class=\"button_wrap\"><a href=\"http:\/\/journals.cambridge.org\/action\/displayAbstract?fromPage=online&#038;aid=9568416\" class=\"cmsms_button\" target=\"_blank\">Link to the article<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":4282,"menu_order":0,"comment_status":"open","ping_status":"open","template":"","format":"standard","meta":[],"pj-categs":[79],"pj-tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.9 -
