Certain activities were studied daily in a self‐regulating growth chamber in four maize plants ( Zea mays L. cv. INRA F7 x F2), which had been raised under completely artificial conditions. The transpiration pattern parallels that for photosynthesis, where a marked change occurs at flowering followed by a decline during cob formation. Respiration reaches a maximum at flowering and thereafter remains relatively stable. Final production figures are comparable with those obtained in field plants, but under artificial conditions the water requirement is halved. The results from this study increase our understanding of whole plant physiology and enable us to establish a closer correlation between plants raised in the laboratory and those in the field.
