ABSTRACT
The present research covered the effect of gladiolus
corm storage temperature on the growth and flowering of three cultivars: 'Amsterdam',
'Energy' and 'White Friendship', grown in the glasshouse, starting from February
14. Corms of each cultivar were divided into four groups: I – 12-week storage
at 17°C, II – 12-week storage at 5°C, III – 6-week storage at 17°C and then 6-week
storage at 5°C as well as IV – exposed to preparation treatment at 22-23°C, having
been stored for 4 weeks at 17°C. It was demonstrated that maintaining only the
temperature of 17°C during corm storage was most favorable, since the plants
of all the cultivars flowered at similar dates as those from the corms additionally
exposed to preparation. At the same time plant flowering occurred three weeks
earlier than the flowering from the corms stored at 5°C. In all the cultivars
researched, in each combination, there was recorded a high share of flowering
plants, ranging from 84 to 100%. Irrespective of the cultivar, in the group of
corms stored throughout the storage period at 5°C or at 17°C, there were reported
shorter stems than those from the corms stored at 17°C and then prepared. The
corm storage temperature did not affect the spike length, the number of florets
and foliage leaves or the stem diameter.
Key words: Gladiolus, corm storage temperature, corm preparation.
