Ornamental Value of Gladiolus in Garden II

Abstract

The author have investigated the changeability of flowering periods and their modes according to the planting time from May to June. When the corms was planted in different periods, they flowered not the same time by their natures. The fourteen varieties of Gladioluses was planted in May and June, aim to investigate their flowering periods and modes in summertime.
The result was that I found difference between their flowering periods and modes of the periods, even as same varieties.
Also, I found the same phenomenon in the percentage of flowering period at their growing and flowering period of the florets.
I think that the lagest factor is the effect of temperature, therefore Gladioluses must be planted from April to August to bloom among July to October in gardens.
