Some characteristics of Tigrida pavonia Ker. Gawl.

Abstract

In 1988, sampling was done from 50 shoots of Tigridia pavonia Ker. Gawl (Iridaceae) from non-divided corns planted in November 1987. The objective was to obtain data on the relationship of the shoot height, number of shoots, and number of fruits with seed production. The following results were obtained: life of flowers is one day, but the flowering period is rather long and continues for one to two month. This is due to the time spacing of the flowering in individual inflorescences every one, two, three or four days and to the gradual entrance in flowering of each lateral inflorescence and the difference in the time of initial flowering of each plant. By planting the corns in groups in garden or pot, we obtained an extended flowering period. The number of flowers or inflorescences, as well as the number of seed yielded, depends on the height of the main shoot. The seed yield and quality (size) are influenced by, harvest date, the earlier one giving higher yield and seeds of larger size. From one fruit 79 seeds were obtained, and one shoot yields from 198 to 950 seeds.
