The impact of step-by-step water deficit on energy content in the biomas of juvenile plants of maize
2009
Abstract
In greenhouse experiments, we have monitored the energy content in 14 genotypes of maize. Juvenile maize plants were cultivated in two versions of the experiment – a control version and a stressed version.
The control plants were irrigated with 70 % of the field water capacity. For the stressed version, irrigation was completely discontinued for sixteen days.
The lowest level of net energy by root was in the genotype (704x23)x23 (12.34 kJ.g-1) and energy content by shoot was in the genotype (704x23)x(704x23) – 12.34 kJ.g-1. The highest net energy content of root was identified in plants (23x704)x23 (13.61 kJ.g-1) and shoot by genotype 23 (14.32 kJ.g-1).
