WebFeb 1, 1995 · As unfertilized silks keep growing for at least 3 days after they first appeared from the husks (Bassetti and Westgate, 1993a) and do not detache easily (Bassetti and Westgate, 1993b), elongated silks were considered unpollinated. Silks with arrested elongation and which were easily detached (Johnson and Herrero, 1981) were considered … WebStay-green (SG) is a term used to describe genotypes that have delayed leaf senescence as compared to reference genotypes. SG could be favorable for grain yield, silage yield and quality, double exploitation (grain for feed and stover for bioenergy), stress resistance, etc. However, some studies show contradictory results regarding the influence of senescence …
