Seed dormancy decreased with time at storage temperatures of \u221212\u00b0, 5\u00b0 or 21 \u00b0C. After 11 months of storage, seeds stored at 21 \u00b0C had 15\u201318% higher germination compared to the seeds stored at \u221212\u00b0 and 5 \u00b0C. The best seedling emergence was obtained at a temperature of 27 \u00b0C when seeds were planted at a depth of 0.5 or 1\u2002cm. Seedling emergence was better in muck or sandy soil than in clay soil. Seedlings developed slowly up to 30 days after emergence at 15 \u00b0C under an 8-, 12- or 16-h photoperiod. High temperatures (27 \u00b0C) stimulated seedling growth under each photoperiod. Taller seedlings with more leaves, longer primary roots, more lateral roots and adventitious root buds grew at 27 \u00b0C as compared to 15\u00b0 or 21 \u00b0C. Increasing the photoperiod from 8 to 16\u2002h increased plant height and number of leaves but not primary root length. <\/jats:p>","DOI":"10.4141\/cjps78-074","type":"journal-article","created":{"date-parts":[[2010,3,17]],"date-time":"2010-03-17T18:48:30Z","timestamp":1268851710000},"page":"493-498","source":"Crossref","is-referenced-by-count":15,"title":["GERMINATION, GROWTH AND DEVELOPMENT OF COMMON MILKWEED"],"prefix":"10.1139","volume":"58","author":[{"given":"PRASANTA C.","family":"BHOWMIK","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"155","container-title":["Canadian Journal of Plant Science"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.nrcresearchpress.com\/doi\/pdf\/10.4141\/cjps78-074","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,5]],"date-time":"2020-01-05T17:42:02Z","timestamp":1578246122000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.nrcresearchpress.com\/doi\/10.4141\/cjps78-074"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1978,4,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1978,4,1]]}},"alternative-id":["10.4141\/cjps78-074"],"URL":"https:\/\/doi.org\/10.4141\/cjps78-074","relation":{},"ISSN":["0008-4220","1918-1833"],"issn-type":[{"value":"0008-4220","type":"print"},{"value":"1918-1833","type":"electronic"}],"subject":[],"published":{"date-parts":[[1978,4,1]]}}}
