Fig. 6. Relationship between relative kernel moisture during grain filling and (A) kernel dry weight accumulation and (B) accumulation of percentage maximum dry weight achieved within each treatment combination. Holdens LH198 × LH185 (closed symbols) and Dekalb DK611 (open symbols) maize plants were grown at three stand densities (one, eight and 18 plants m^–2) and exposed to natural or restricted pollination treatments that altered the post‐flowering source–sink ratio.
