Abiotic anxieties are appraised to be the focal root for worldwide garner revenue
reduction and, considered as a pronounced restraint to agriculture.Therefore, it is
especially important to cognize plants' responses to such stressors, predominantly those
heavy metals which act as micronutrients of plants. The potato peel surface was applied
in order to find probable solution of this existing problem, especially for those areas
where industrial wastewater is commonly used for irrigation of daily consumable crops or
vegetables.
This investigation based on such cost-effective technology which the farmer can easily be
used at their main receiving channel of irrigation. For this purpose, potato peel surface
was prepared by blazing and characterized via using SEM technology then used for
recycling of laboratory prepared wastewater. The recycled water was used for cultivation
of two important vegetables in comparison with plants grown in normal tap water and
metal contaminated water.
The ionomics (trace metals) tool was taken into consideration to state the related
problems for better solution. The cultivation of three traits provide valuable information’s
about ionomics impacts on ecosystem in relation with mushroom, weeds, insect’s growth
and bird negligence towards metal mediated plants. The altered leaves structure and
reduced stomatal size was accountable for reduced growth rate and adapted mechanism
for survival in metal contaminated environment which was successfully controlled in
recycled water.
The data obtained described the accumulation of metal in plant and alteration which the
plants respond at cellular level in presence of metal and its remediation results in the
improvement in the biological mechanism in traits of which have been cultivated in the
recycled wastewater for enhanced biomass production. Exposure of excessive
concentration of Cu metal in plants b triggers a wide range of physiological and
biochemical modifications like reduced growth rate, photosynthetic activity, disturb C, N
metabolism with high proline and phenol accumulation. This was related to the
generation of ROS (reactive oxygen species) usually produced in presence of Cu metal
xxxii
due to which plant responded defensive mechanism for absorption of ROS species while
traits in recycled water showed normal mechanism which covers up decrease in the
photosynthetic pigments, repair of damage chloroplast membrane, C, N metabolism with
decrease enzyme activity. Furthermore, reduced growth rate in seedlings of plants b were
observed up to maturity level with modified structure of fruit and flower, when seeds of
plants b were grown in regular garden soil with irrigation by normal tap water in
comparison of seeds of plant a and c showed abnormal growth rates. This modified seeds
structure of plant b acquired, in contaminated environment, was alarming to us and
indicates the need of technology which can give the support in crops augmentations for
competitive population of the world. Hopefully this technology will provide support to
farmer for their improving crops quantitatively and qualitatively without scarcity of
water. |
