An integrated model on plant photothermal responses has been developed under the principle that photoperiod and temperature are inextricably interacting in their modulation of plant growth and development, which describes photoperiodism, vernalization and other kinds of temperature responses of both long-day plants and short-day plants by a single pattern.
the average photosynthetic biomass productivity in Special-early Maturity Sub-region was biggest and the value was 46.563g·m-2·d-1. (2) Cotton average light temperature productivity of lint and cotton average light temperature biomass productivity were 5520.576kg·hm-2 and 12.860g·m-2·d-1 respectively.
As far as the whole region is concerned, the limited light temperature productivity of lint was 6242.806kg·hm-2 (in Tulufan) and the most light temperature biomass productivity was 14.244g·m-2·d-1 (in Wusu).
As for the Sub-region, both the average light temperature productivity of lint and the average light temperature biomass productivity in Mid Maturity Sub-region were highest and they were 6190.401kg·hm-2 and 13.619g·m-2·d-1 respectively.
Given the usually strong synchronizing role of light and temperature, it is surprising that 5 of the 12 cardiovascular series had a numerically larger amplitude of the 1.3-year versus the precise 1.0-year component.
The effects of light and temperature conditions on the maintenance of some red microalgae (order Porphyridiales) in collections were studied.
Light and temperature dependencies of the chlorophyll oxidation rates were similar to those of the DF of PSI.
The dependence of this manifestation on light and temperature was observed only at the early stage of development of pigment-containing tissues.
Heat hardening (3 h at 38-39°C) improved the tolerance of photosynthesis to combined action of high light and temperature but did not affect the tolerance to photoinhibition at 30°C.
