Bamboo Growth (Dracaena sanderiana) Essay -- Environment, Lucky Bamboo

This research was conducted to investigate light intensity effects on lucky bamboo vegetative growth in Azad University, Abhar Branch during 2008. The experiment was arranged as a complete randomized block design with 5 treatments (0.75, 1.14, 1.89, 2.29 and 4.09 Â µmol∙m-2∙s-1) in 10 replication. Results showed that 1.89 Â µmol/m-2/s-1 had significant differences from others treatments. The higher level of root number, shoot length and total weight of plants were obtained in 1.89 Â µmol∙m-2∙s-1 reatment. Number of shoot, shoot length and number of leaf per shoot were differ in different nodes and were highest in upping nod. Seedlings characteristics are during the growth time as a crucial factor in determining the ultimate fate of the plants. Therefore should be tried always seedlings have to very good condition. Seedling growth and quality are under influenced by environmental factors including light intensity (Lavendar, 1984). If environmental factors such as light intensity changes, also are under affect other factors and final quality of seedlings (Chaar et al., 1997). Seedling producers with changing and optimizing the light intensity regulated the seedlings growth, development, and plant vegetative quality (Lavendar, 1984). Lucky Bamboo with the scientific name Dracaena sanderiana has owned to Dracaenaceae family. This variety of dracaena does not belong to real bamboos of the Poaceae family. This plant are popular because beautiful leaves and robustness to apartment conditions. This plant is among plants that allowed indirect and low light intensity. So they classified in plants group with low light need (Brown, 2008). Brown (2008) reported ... ...results of this experiment showed that Lucky Bamboo is including Plants that have required too little light intensity. High light intensity can be cause yellowing of leaves. If want of results these experiments have a general recommendation for keeping these plants in apartment thus can say Because the total amount of light produced by sodium lamps with 400 watts at 3 meters distance is equivalent to 19 Â µmol s-1m-2. So use of a sodium or fluorescent lamp with 40 watts can to provide power equal to 1 / 9 Â µmol s-1m-2 for the plant (Barzegar & Yadegari, 2010). As that observed of this experiment the best treatment of light intensity for the optimum growth in Lucky bamboo plant is equivalent energy to 1 / 89 Â µmol s-1m-2. Can also provided light intensity needed for this shade-friendly plant with use a 40-watt incandescent lamp at a three meters distance apartment.
