“…The higher growth and activity of phosphate solubilizing bacteria as well as high acid phosphatase activity affected greater solubilisation of insoluble inorganic phosphate compounds and mineralization of organic P, which in turn enhanced the available P status in jute-rice-potato and juterice-ladies finger cropping system in particular and Hooghly district as a whole compared to Nadia and North 24 Parganas districts. This is also supported by the findings of Das and Debnath, (2006), Majumdar et al, (2010) and Das et al, (2012).…”

“…For example, Battah et al ( 2001 ) showed that high concentrations of phosphate alleviated the toxic effects of thiobencarb ( S -4-chlorobenzyl diethyl (thiocarbamate)) on the growth and photosynthetic activity of Anabaena variabilis . Conversely, Das and Debnath ( 2006 ) showed that herbicides stimulate the growth and activity of aerobic non-symbiotic N 2 -fi xing bacteria and increase the amount of N and P in the rhizosphere. Qian et al ( 2009 ) also reported that exogenous nitric oxide protects Chlorella vulgaris from the toxicity of herbicides by reducing the damaging effects of oxidants and increasing the transcription of related genes.…”

Abiotic Stress Responses in Plants

Several environmental factors infl uence the mineral uptake of plants, including pH, redox potential, and the presence of xenobiotics as well as the temperature and salinity. Changes in environmental conditions affect the biological and physiological response of plants. Most important targets of plants are maintained by the ion homeostasis and mineral uptake in stress conditions. Plants may use the different procedures to regulate homeostasis. In general, Na salt stress decreases the levels of cationic nutrients such as K, Ca, and Mg due to competition for ion transport sites. Drought and salinity stress are physiologically related and the tolerance mechanisms overlap. Metals can interfere with mineral nutrition and change the concentration and composition of plant nutrients. Besides, metals may also alter the conformation of proteins, including transporters, or regulator proteins. Herbicides may disrupt the function and integrity of the cell membrane, and signifi cant ion losses can occur. However, molecular mechanisms and genetic basis of interactions between abiotic stress and mineral uptake is lacking. Thus, future studies will focus on these aspects. In this chapter, the effects of some common stressors, such as salinity, drought, metals, herbicides, and on nutrient uptake are elucidated.

“…Na osnovu istraživanja u oblasti fiziologije biljaka utvrđeno je da korenske izlučevine čine oko 5% od biljne mase, što značajno utiče na kvantitativnu i kvalitativnu zastupljenost mikroorganizama. Izlučevine korena razlikuju se po hemijskom sastavu u zavisnosti od biljne vrste i kao takve ugrađuju u mikrobnu biomasu (Das & Debnath 2005). Količina i sastav organske materije utiču na formiranje mikrobioloških zajednica u zemljištu.…”

Izvod: Mikroorganizmi učestvuju u stvaranju plodnosti zemljišta, kako potencijalne tako i efektivne. Mikroorganizmi omogućavaju odvijanje procesa humifikacije i dehumifikacije i zauzimaju centralno mesto u kruženju neophodnih hranljivih makro i mikroelemenata. Zona zemljišta koja okružuje korenov sistem biljaka i pod uticajem je njegovih izlučevina može se definisati kao rizosfera. Svojim korenskim izlučevinama kukuruz može značajno da utiče na sastav i brojnost mikroorganizama u rizosferi. Biofertilizatori su mikrobiološka đubriva koja sadrže selekcionisane visoko efektivne sojeve bakterija, algi i gljiva izolovane iz zemljišta. Njihovim unošenjem u zemljište aktiviraju se odgovarajući mikrobiološki procesi koji omogućavaju bolje i ravnomernije snabdevanje biljaka azotom, fosforom i kalijumom, kao i nekim mikroelementima. Primenom biofertilizatora koji sadrže rizobakterije promotore biljnog rasta -PGPR (Plant Growth Promoting Rhizobacteria) smanjuje se upotreba skupih azotnih đubriva, omogućava se biljci lakše usvajanje fosfora i utiče na pravac i dinamiku mikrobioloških procesa.
