Abstract
The growth of the cultivar Golden Princess Anne (G.P.A.) was studied in controlled announcement cabinets in a range of light conditions (125–375 J cm −2 8-h day −1 ) and carbon dioxide concentrations (325–1500 ppm) in all combinations Plants obtained in January and grown from January to April showed greater final total dry weight and flower dry weight at both higher light intensity and higher carbon dioxide concentration with a strong positive interaction between them, whereas plants obtained in September and grown from September to December did not respond much to increased carbon dioxide concentration and there was only a small positive interaction with light intensity. The plants grown from January to April had larger final leaf areas, larger mean leaf-area ratios due mainly to larger specific leaf areas, and higher mean specific leaf-water contents compared with September–December plants. Despite the difference in specific leaf-water content, leaf area was almost the same linear function of absolute leaf-water content at both times of year. The other vegetative parts also had higher specific water contents throughout the January–April experiment and the lateral branches were longer when compared with the corresponding values for September–December Flower development was slightly faster in September–December and the plants bore on average one flowering branch less compared with January–April plants. Plants in the lower light and carbon dioxide conditions had lower unit leaf rates, but for plants of similar total dry weight the effects of this on dry-matter increment were partially offset by larger leaf areas at both times of year. The January–April plants had greater leaf areas than September–December plants of similar unit leaf rate and total dry weight. The cultivar Bright Golden Anne (B.G.A ) showed effects which were in the same direction but smaller in magnitude, tending to diminish the differences between the times of year For example, the positive interaction in total plant dry weight was smaller in January–April compared with G P A , but larger in September–December. Leaf area, leaf-area ratio, specific leaf area, specific water content of leaf, stem, and root, and lateral branch length, were all larger for B G A in corresponding treatment-combinations in two January–April experiments than in a September–December one, although the difference between the times of year was smaller than for G.P.A except for leaf area which was relatively but not absolutely smaller Dry-matter increment and leaf area showed an inverse relationship for plants of the same total dry weight, as in G P A. In January–April B G.A plants of similar unit leaf rate and total dry weight also had greater leaf areas than in September–December but the differences were not so large as for G.P.A Total dry-matter production was slightly greater for B.G.A. in January–April and considerably greater in September–December compared with G P A , and at both times of year B.G.A. was more leafy, with higher specific water contents for the vegetative parts. It was not possible to determine the cause of the differences in growth obtained at the two times of year. It could have arisen before the cuttings were removed from the stock plants, during propagation, or during the course of the experiments in the growth cabinets.
