Abstract EN

Two separated experiments were conducted to show brightly the rhizome and pots size effect on the vegetative and floral growth, rhizomes yield under protected cultivation conditions (Glass House and Lath House).

The experiments were used the design as Randomized Complete Block Design (RCBD), every experiments included two factors, the first was rhizome size which contains three sizes in depending on the diameter (2.5 - 3 and 3.1 to 3.5 and 3.6 - 4 cm), while the second factor was the pots size which were (11, 12, 14 inch).

The results showed the superiority of the big size on rhizome in plant height, leaves number which mentioned highest value of 25.78 cm and 7.32 leaves inside the glass house, and also caused flowering advancing with 122.00, 134.50 days for the two situations.

The rhizome size investigate high height, diameter, wet weight of inflorescence and flowering period reached to 41.25, 44.48 cm and 12.13 , 12.51 mm and 15.24, 22.12 g and 14.00 , 14.30 day for the two places successively.

The pot size appeared superiorly of small one in vegetative growth, bud numbers and leaves numbers 24.05 cm and 2.10 bud.rhizome-1 and 7:44 leaf for plant grew in a glass house, while the grand pot effect on flowering advancing needed 119.16, 132.27 days for two places successively, as well as that flowering period, high height and diameter of inflorescences 16.33, 12.33 days and 43.65, 42.08 cm and 13.58, 11.33 mm for two places successively.

The results showed also superiority in plant properties planted in the lath house compared with plants planted in glass house so investigated highest growth vegetative, bud numbers and leaves numbers reached to 44.80 cm and 2.32 bud.rhizome-1 and 9.99 leaf, but the plants need longest period till flowering reached to 149.91 days, as well as flowering plant increased to 48.88% with flowers wet weight reached to 19.16g.
