| Abstract:
The evolution of some indexes together with morphological characteristics of red garlic sprouts were evaluated, during post-harvest storage, as indicators of the sprouting inhibition method (application of Maleic Hydrazide or commercial doses of gamma rays). Those indexes were calculated on the base of macroscopic morphological parameters. From the end of dormancy onwards both showed, clearly, differences between treated and control bulbs. The effects produced by gamma irradiation, but not by MH, were observed in the colour and swelling of sprouts as well as the absence of mitosis and abnormalities in the nuclear morphology of meristematic cells from irradiated bulbs. These results are in agreement with the primary effects expected by each of the treatments. The parameters and characteristics evaluated could be used, from the end of dormancy onwards, to identify the inhibition method applied. | |
