Juvenile phase

The effect of zearalenone on crop development may be connected to its influence on the status and functioning of the photosynthetic apparatus (Koscielniak et al. 2008). The after-effects of zearalenone on the growth of soybean and wheat plants, net photosynthesis and transpiration rates, stomatal conductance, photochemical efficiency of photosystem 2 and on final seeds yield were determined. Modifications in leaf area were more pronounced in soybean than in wheat, and this tendency increases in successive developmental phases. The net photosynthesis was stimulated during the juvenile phase and during that of the final one by about 13.6% (average) in soybean plants. Stimulation of transpiration was also observed after...

Completion of a juvenile phase of ontogenesis is usually associated with the development of floral buds, but a lower part of a young tree crown may remain in a juvenile stage whereas flowers are formed in its upper part and a yoimg tree enters an adult phase getting an ability of fruiting [12].
