Other claims from this paper (9)
- Observation The whole wheat plant increased in weight until about a week before it would be regarded as ready to cut.
- Observation The nitrogen, ash and phosphoric acid of the whole wheat plant increased until about a week before ready-to-cut.
- Observation Dry weight of wheat decreased during the last week before cutting.
- Observation Grain formation in wheat passes through three stages.
- Mechanism The character of the endosperm mould of each wheat plant is determined by variety, soil and season.
- Observation The main feature of wheat ripening is desiccation rather than chemical changes.
- Observation The maximum dry weight of wheat grain is attained a day or two before the grain would be regarded as ripe.
- Intervention effect Cutting wheat before the corn appears quite ripe incurs no loss of crop weight.
- Intervention effect Early cutting before full ripeness may avoid accidental mechanical losses of wheat.
