This richly illustrated reference text, with more than 350 figures and illustrations, presents general angiosperm embryology as it applies to economically important plants. The unique focus on economically important species increases the relevance of this book to today's students and researchers in the plant sciences. Lersten emphasizes the plant species that affect human livelihood, includ 606 $aPlant embryology 606 $aAngiosperms$xEmbryology 615 0$aPlant embryology. 615 0$aAngiosperms$xEmbryology. 676 $a571.862 700 $aLersten$b Nels R$0312648 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910829837003321 996 $aFlowering plant embryology$9807326 997 $aUNINA LEADER 01696nas 2200493- 450 001 9910258359103321 005 20241221110052.0 035 $a(OCoLC)952435107 035 $a(CKB)2660000000038275 035 $a(CONSER)--2023241940 035 $a(MiFhGG)9BAR 035 $a(DE-599)ZDB2932178-5 035 $a(EXLCZ)992660000000038275 100 $a20160628a20169999 --- - 101 0 $aeng 135 $aurmn||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aCitizen science $etheory and practice 210 1$aLondon, United Kingdom :$cPublished by Ubiquity Press on behalf of the Citizen Science Association,$d2016- 215 $a1 online resource 300 $aRefereed/Peer-reviewed 311 08$a2057-4991 320 $aIncludes bibliographical references. 606 $aScience$xCitizen participation$vPeriodicals 606 $aVolunteer workers in science$vPeriodicals 606 $aSciences$xParticipation des citoyens$vPériodiques 606 $aScience$xCitizen participation$2fast$3(OCoLC)fst01108196 606 $aVolunteer workers in science$2fast$3(OCoLC)fst01169101 608 $aPeriodicals.$2fast 608 $aZeitschrift.$2gnd-content 608 $aSerial publications.$2lcgft 615 0$aScience$xCitizen participation 615 0$aVolunteer workers in science 615 6$aSciences$xParticipation des citoyens 615 7$aScience$xCitizen participation. 615 7$aVolunteer workers in science. 676 $a507.2 712 02$aCitizen Science Association, 906 $aJOURNAL 912 $a9910258359103321 996 $aCitizen Science$94132403 997 $aUNINA
