In experiments at Niphad large mother bulbs produced more seed heads, more seeds per head and a greater weight of seed per plant than smaller bulbs. In addition the smaller bulbs lost more weight in storage, and suffered more rotting than the larger ones. The larger bulbs also came into bloom earlier.
