概要 |
One of the most important criteria to be met by traditional climatic plant growth equipment is that the programmed environmental conditions should be completely homogeneous, i.e. all the experimental ...plants in the given phytotron unit should be exposed to identical environmental effects. In Martonvasar a plant growth unit differing fundamentally from these criteria has been produced, in which regular inhomogeneities (gradients) can be set up perpendicular to each other for two chosen environmental factors. In the gradient bench perpendicular gradients of two selected environmental factors can be programmed in such a way that a large number of combinations of the two factors will be created simultaneously in a single plant growth unit, while all the other factors are identical. As regards the methodology of the experiments, it is a further advantage that the timespan of the gradient effects can also be programmed as a third variable.続きを見る
