Petunia Hybrid Shows Variation in Growth Due to Influence of Biotic and Abiotic Stress Components

Abstract

In natural environment, biotic and abiotic stress component influences the growth of plants. They always affect the development of plant in the different forms. Some plants have ability to encounter stresses by changing their morphological, physiological and biochemical activities. But some plant can‟t accommodate with these stresses and have negative impact due to reduction in photosynthetic activity, reduced transportation of water etc. Here, certain biotic and abiotic factors are applied to Petunia hybrida plant and then influence and reactions are studied for selected time period. Common garden Petunia- Petunia hybrida is derived from P.integrifolia and P.axillaris. Here, the applied factors are „wood ash extract‟, „high temperature and light‟, „temperate and cold water‟ as abiotic factors and „neem leaf extract‟ and „competition between plants‟ as biotic factors.
