ABSTRACT

A field experiment was conducted in the years 2000-2003. The corms of Sparaxis tricolor were planted in spring at the following dates: 20.04, 29.04, 10.05 and 20.05 at 3 depths of planting: 4, 6 and 8 cm. The greatest number of inflorescence stalks growing from 1 corm was obtained planting Sparaxis at the earliest of the studied dates. The length of the main shoot, the length of the spike, the number of inflorescences in a spike as well as the diameter of the first flower were also the biggest when the corms were planted at the turn of the second and third 10-days’ period of April. More inflorescence stalks were obtained planting the corms at the depth of 4 cm. Deeper corm planting at the depth of 6-8 cm had a positive effect on the diameter of the first flower in the inflorescence and the length of the leaves. The studies observed a positive effect of earlier planting on the formation of inflorescence stalks containing at least 5 flowers in a spike. Their proportion range in particular years was from 15 to 40% for Sparaxis planted on 20 April and it decreased to 6-17% when the corms were planted on 20 May.

Key words: Sparaxis tricolor, planting date, planting depth, flowering.
