Abstract:

In this paper, two-years-old seedlings of Quercus variabilis and Platycladus orientalis were subjected to the following treatments: full sunlight+wind; full sunlight without wind; shading+wind; shading without wind, to segregate irradiation from wind effect on growth and morphogenesis of the seedlings. After two-month treatment, wind blowing significantly inhibited height growth of the two species. However irradiation itself did not change their height growth. Diameter growth of P. orientalis was promoted by irradiation, but not related to wind blowing. Both irradiation and wind increased taper of P. orientalis stem, while they did not change taper of Q. variabilis stem. Irradiation with wind enhanced root growth of P. orientalis, but the two environmental factors did not change the root/shoot ratio. In general, wind, but not irradiation, inhibited height growth of the two species. The two species had differential responses of growth and morphogenesis to irradiation and wind. Wind blowing had relatively more significant inhibition to Q. variabilis growth, not only height growth but also assimilation, stomatal conductance, diameter and root growth. In contrast, wind did not significantly change the above processes of P. orientalis except for its height growth. Irradiation promoted diameter growth of P. orientalis, and along with wind increased root growth. However irradiation did not vary the processes of Q. variabilis.

Key words: irradiation, wind, growth, morphogenesis, Platycladus orientalis, Quercus variabilis
