Identification of the method used to inhibit sprouting in garlic.

Micro- and macroscopic changes observed in red garlic (cv. Colorado) bulbs which had been treated with 2 sprouting inhibition treatments (application of maleic hydrazide at 15 litres/ha 2 weeks before harvest or irradiation with 60 Gy using 60Co gamma rays 30 days after harvest) were compared to determine whether it is possible to identify which of the 2 treatments has been applied (maleic hydrazide is banned in some countries). The bulbs were stored under ambient conditions and sampled at harvest and 30 (full dormancy), 90 (end of dormancy), 120 (beginning of sprouting) and 240 (decaying bulbs) days after harvest (DAH). Macroscopic differences were observed between treated and non-treated (control) bulbs from 120 DAH onwards. Differences in the percentage ratio of the length of the naked sprout and the length of the storage leaf 120 and 240 DAH were suitable for distinguishing between control bulbs, bulbs treated with maleic hydrazide and irradiated bulbs. Irradiation, but not maleic hydrazide,

 affected the colour and swelling of sprouts and resulted in the absence of mitosis throughout the entire observation period and abnormalities in the nuclear morphology of meristematic cells.
