Effect of sowing dates on germination of common water hyacinth (Eichhornia crassipes Mart) solms in Central Iraq
Abstract
Keeping in view, the importance of water Hyacinth (Eichhornia crassipes Mart.) Solms in reducing the biological diversity, this research was aimed to determine the seed germination percentage in suitable environmental condition in order to stop its further extension to improve the long-term management particularly in Diyala province. This study included the identification of the seed ability to germinate and the environmental circumstances affecting the propagation of the water Hyacinth plant by seed. Three sowing dates of different months for seed were selected (March, April and May). The experiment was designed with three replicates using the Randomized Complete Block Design. The results of the experiment indicated the seed germination average was 84% in general and germination occured only at the temperature range of 28-35 ºC that went through three stages (Germination, floating and growth of the plant).The plant produced six to seven daughter plants within nine to eleven days after floating. The seed sown on the 20th of March (the first date) needed 43 days to germinate. The percentage of time saving of the floating time laps in the third sowing reached 44.54%. The seed sown on the 20th of March provided advanced plant height 13.2cm.The third seed sowing date of the 20th of May showed higher root length 25.45cm. Leaf area indicated 1.743 m2 in the third seed sowing. Green plant weight as the first seed sowing date reached 4775.2gm/m2. The present information will be usefull to manage this invasive plant through the world.
