Starch is polysaccharide which play important role in the metabolism of living organisms. In addition, starch are raw materials in the food and materials industry. Increasing the starch content of crops based on improving the activity of some genes encoding enzymes plays an important role in the process of biosynthesis and accumulation of starch, which is one of the research are of interest. Like in bacteria, the process of starch biosynthesis in plants occurs by using ADP-Glc as raw materials to

Soil texture is classified based on the amount of sand, silt and clay present in a soil sample (Schoonover & Crim 2015). A coarse soil is a sand or loamy soil, a medium soil is a loam, silt loam or silt whereas a fine soil is a sandy clay, silty clay or just clay (Ball 2001).

Fig 2. Effects of drought stress on photosynthesis. Drought stress causes accumulation of reactive oxygen species by disturbing the balance between productions of reactive oxygen species and the antioxidant defense which induces oxidative stress. During drought stress plants close stomata which decrease the CO2 influx. Besides reducing the carboxylation reduction in CO2 also directs more electrons to form reactive oxygen species. Under severe drought condition photosynthesis is limited by decrease

Other plants with narcotic properties in this family are mandrake (Mandrogora), belladonna (Atropa), henbane (Hyoscyamus), and tobacco (Nicotiana).
