For example, comparing the zymograms of trees in a polluted area with those of other trees in a non-polluted area will produce ambiguous results unless the trees at both locations are ramets of the same clones.

Natural variation in sensitivity of reproductive processes in some boreal forest trees to acidityelationship between these population parameters will be discussed in terms of a possible mechanism of assortative mating between adjacent populations for the maintenance of adaptation to local soil conditions.

Selection effects of air pollution in Norway spruce (,) populationsnces between the two subsets could be found at four gene loci (GOT-B, G6PDH-A, GRD-A and PEPCA-A), however, the type of difference varied among the enzyme loci. In general, the patterns of subset differentiation did not markedly differ between the clone collection and the tree stands and showed surp作者: 辮子帶來幫助 時(shí)間: 2025-3-22 21:56
The importance of genetic multiplicity for tolerance of atmospheric pollutionbe found in the fact that, measured on the average generation time of trees, air pollution constitutes a rapid, complex, globally active and unidirected environmental change. As to the present state of our knowledge, it is very unlikely that forests can ever adapt to and survive such catastrophic co作者: 額外的事 時(shí)間: 2025-3-23 03:36 作者: KIN 時(shí)間: 2025-3-23 09:16 作者: antipsychotic 時(shí)間: 2025-3-23 10:59

Response of , (L.) Karst. provenances to aluminum in hydroponicsseed stands. Al concentration in the needles was negatively correlated with the growth traits. Exposure to Al caused a decreased uptake of several nutrient elements; Ca, Mg were affected mostly whereas K and P uptake were slightly reduced by Al. An intraspecific variation in element concentration was, with the exception of K and Al, not observed.作者: 朦朧 時(shí)間: 2025-3-25 12:37 作者: 吊胃口 時(shí)間: 2025-3-25 18:08 作者: 發(fā)源 時(shí)間: 2025-3-25 22:50 作者: 運(yùn)氣 時(shí)間: 2025-3-26 03:51
