Abstract

Present study was conducted to investigate the Detrimental effects of Drought and salinity stress on floral diversity and how physical symptoms appear after these stresses. Plants in their natural habitats adapt to stresses in the environment through variety of mechanisms. But stresses are harmful with their exceeding concentrations that damage the floral diversity. Study was completed by different surveys during May 2017 to August 2019.  40 plant species were collected and sample were tested and observed to check physical symptoms in plants parts like fruit, flower, leaves, stem and roots.  Plant species recorded under salt stress were 57.5%, drought stress 22.5% while combine affect of both salinity and drought in plants were 20%. Growth of many plants were badly affected by drought and salinity stress. Fruit and flower of the plants were much reduced, Stem was stunted, leaves mostly were wilted and roots were hollow and poor. Halophytes and drought tolerating plants were best in their growth. Overall floral diversity was under stress that was limiting the natural habitats.
