IMPACT OF DIMETIPHINE, ETEPHON AND DIQUAT ON THE HEALTH STATUS OF WHITE LUPIN SEEDS (LUPINUS ALBUS L.)
Małgorzata Jeske, Janusz Prusiński
ABSTRACT
The research investigated the seeds of ‘Bardo’ traditional cultivar, and ‘R-141’ self-completing white lupin cultivar. Over 1996-1998, once the seeds reached their physiological maturity, the plants were treated with Harvade 250 SC (dimetiphine), Ethrel (etephon), plant growth regulators and Reglone (diquat), a desiccant. Seeds harvested from plants whose sowing material was vernalised and two-stage harvest seeds constituted objects 4 and 5. The seeds collected each year were divided into two categories based on a visual ‘healthy and infected’ selection. The share of the latter group in the seed yield of both two-stage harvested cultivars was highest, while having applied Ethrel (‘Bardo) and Harvade ‘(R-141’) as well as following seed vernalisation (both cultivars), the share turned out lower. ‘R-141’ self-completing yield included significantly fewer seeds with fungal infection symptoms than the ‘Bardo’ traditional cultivar. ‘Healthy and infested’ seeds of each combination we
