Abstract:
In an experiment with Chrysanthemum - Indicum - Hybrids (C. x hortorum L.H. Bailey) the influence of different substrates and moisture regimes on the growth and quality of the cut flowers was examined.
The moistures have been regulated by tensio-switches or ceramic plugs.
The vase life of the cut flowers was studied after pretreatment.
The following results have been obtained:
- The yield of the shoots was smaller with decreasing moisture of the substrates.
High moisture contents of the substrates resulted in high weights of flowers and shoots.
- Though highly stressed by drought the outer quality of the cut flowers and the length of the flower stems (≥80 cm) were still good enough for commercial purposes.
- The decrease in yield with falling moisture contents of the substrates was more pronounced with peat substrate (TKS 1) than with peat clay mixture (E - Erde P). The highest yield was reached with TKS 1 and high moisture contents.
- The number of buds and flowers was nearly independent of the treatments.
- The vase life of the leaves and flowers increased with decreasing moisture contents of the plant substrates.
