| Investigations were carried out on the suitability of potassium metabisulphite (pyrosulphite, KMS) as a preservative agent in sugar cane crossing solution. It was confirmed that KMS ensured the survival of flowering stalks and allowed the unfolding of spikelets along the panicle to proceed in a normal way. At equal concentrations of 100 ppm SO2, no differences in days to harvest and fuzz weight were detected in gaseous SO2 and KMS treatments. With respect to seed setting, the average number of seedlings obtained from sowing a fixed weithy of fuzz was slightly superior for the KMS treatment but the reverse was true when the average seedling yield per panicle was considered. Differences between varieties were highly significant for all the characters measured but variety X treatment interaction was significant for seedling count only. In one series of observations, a high concentration of SO2 from a KMS source (300 ppm) proved detrimental to seed setting. Closer analysis of the data may favour gaseous SO2 as the best preservative agent but KMS at 100 ppm SO2 constitutes a good substitute. Its low cost, ease of use and ease of storage offsets its slight depressive effect on seed setting (if the effect is real). | |
