We selected two different scale parameters, leaf chlorophyll content and leaf area index, on the basis of the radiative transfer models PROSPECT and SAIL, respectively, for sensitivity study of a set of indices. We aimed to improve the linearity between the indices for chlorophyll content and leaf area index on the basis of combinations of different wave bands.

Effects of gamma irradiation on shoot regeneration from leaf and bud growth in vitro of strawberry 1 The leaf was very sensitive to the gamma irradiation, and 'Toyonoka' was more sensitive than 'Akihime'. The LD50 (50% decrease of generation) of strawberry leaf was between 10 and 20 Gy. 2 Strawberry leaves were inoculated in vitro at 8 d-15 d after gamma rays irradiation, and the shoot regeneration rate from of 'Toyonoka' increased at 10 Gy and almost no difference from 20 Gy to 40 Gy. The positive effect dose for 'Akihime'.was from 10 Gy to 30 Gy, however, 40 Gy decreased shoot regeneration rate.

After pretreatment with TFP, although the conductance of cultivate solution of strawberry seedling under NaCl stress was not increased, growth was inhibited obviously by TFP, while the leaf relative electric conductivity in strawberry increased, leaf holding ability was reduced. The inhibiting response increased with the concentration of TFP increasing. On the contrary, conductance in cultivate solution was increased by Ca(NC?3)2 treatment, but the leaf relative electric condu
