Available in PDF, EPUB and Kindle. Book excerpt: Produire des semences et des plants certifiés, c’est concourir au progrès agricole que permet l’évolution constante de la génétique et de ses applications. Cinquante pour cent de la productivité des principales productions agricoles lui sont redevables. Cependant, la législation actuelle fait débat : en effet, elle tend à se durcir afin d’apporter des garanties pour l'utilisateur sur la qualité germinative, la pureté spécifique, la pureté variétale, l'état sanitaire, et à encadrer la production des semences commerciales. Cette nouvelle édition de Semences et plants a pour vocation de faire un point sur l’état actuel de la production de semences et de plants certifiés au vu des récentes évolutions de la réglementation. Les bases scientifiques et les données techniques inhérentes à cette production sont largement développées. Documenté et complet, cet ouvrage s’adresse aux étudiants et aux formateurs de l’enseignement agricole, aux agents du développement agricole et aux agriculteurs – qu’ils soient multiplicateurs ou usagers – qui y trouveront les connaissances techniques et économiques qui leur sont indispensables.
