Study The Seed Germination in Different Time of Planting on Propagation and Growth of Eichhornia crassipes (Mart)Solms in Northern Iraq.

Abstract

The experiment was conducted during spring and summer 2011 at field of the college of Agriculture and Forestry in Naniva Province (Iraq) to study the effect of different time of seed planting (March ,April ,June) on seed germination ,growth and propagation .It use a simple experiment in (RCBD) with three replicates . The results showed that in general the germination was 87% .The seeds were germinated during the duration of the season growth under temperature of 28-35 Cْ and in light ,but seeds under mother plant can not germinated in the dark. However ,the seeds germinated in water passing three stages ,After germination ,the seedlings remains attached to the mud. After some times the seedlings get detached from the mud and become free floating .It then multiplies vegetatively .Furthermore ,The individual plant had created from single seed germination gave 206 daughter plant with 2.199 m²/ m² leaf area and the mat covered 1/44 m² after 64 days. So this plant has a potential of producing seeds and propagates for high propagation and growth.
