Other claims from this paper (19)
- Observation Leaf blade dry weight of maize showed little variation during the ear-filling period.
- Observation Stem dry weight of maize increased slowly in the first half of the ear-filling period and then increased or decreased in the latter half.
- Observation Ear dry weight of maize increased linearly, with extremely large differences among years.
- Association Top dry weight of maize was affected remarkably by ear weight, giving large differences among years.
- Observation Top dry weight growth rate (CGR) of maize peaked at about silking with a unimodal curve.
- Observation Top dry weight growth rate (CGR) of maize showed a rapid decrease during the ear-filling period.
- Observation Net assimilation rate (NAR) of maize tended to reach a maximum in the 3 weeks before silking.
- Observation Leaf area index (LAI) of maize reached a maximum at silking or 3 weeks after silking and then decreased gradually.
- Association CGR of maize was highly positively correlated with LAI during the 6 to 3 weeks before silking.
- Association CGR of maize was highly positively correlated with NAR during period II and period III.
- Association CGR of maize in period IV was highly positively correlated with both NAR and LAI.
- Association CGR of maize in period II was positively correlated with daily mean, maximum and minimum temperature and with sunshine hours.
- Association CGR of maize in period II was negatively correlated with rainfall.
- Association CGR of maize in periods III and IV was highly positively correlated with temperature factors, sunshine hours and solar radiation, and most strongly with daily maximum temperature.
- Association CGR of maize in period IV was negatively correlated with daily mean wind speed.
- Association Stover dry matter yield of maize was positively correlated with CGR in period II.
- Association Ear and total dry matter yield of maize were highly positively correlated with CGR in periods III and IV, with total dry matter yield showing the highest correlation.
- Association Percentages of dry matter in ear and whole plant and the ear/total ratio of maize were highly positively correlated with CGR in the later growth period.
- Association CGR in the latter half of the ear-filling period had the greatest influence on yield and quality of maize for whole-plant silage.
