AB  - Drought  is  one  of  the  main  consequences  of  climate  change  that  negatively  affects  plant  growth and development, which in turn leads to a reduction in yield. The objective of this study was to investigate the effects of the physiological responses to the drought stress of maize plants (population IP3722), obtained from seeds of different ages (originating from 2012. and 2016) and different previous experience (the seeds formed in 2012. were more exposed to drought than in 2016.). Two populations responded to drought treatment by a significant decrease of shoot fresh and  dry  weight,  this  was  followed  with  decrease  leaf  area  and  transpiration  rate.  Drought  tre-atments enabled induction and differentiation of chemical signals of drought (abscisic acid-ABA and xylem pH) and hydraulic signals (leaf water potential), and monitoring of their activity on stomatal conductance. The data showed that hydraulic signals have the same impact on stomatal reactions in the D2012 and D2016 treatments. They also indicated that the chemical signal of ABA works toward stomatal closure, but that the effect depends on whether it originates from the leaf or the root. Leaf-originating ABA had more effect on the closure of D2012 stomata, while root-ori-ginating ABA and pH was more active in the D2016
AB  - Suša nastaje kao posledica klimatskih promena, koja negativno utiče na rast i razvoj biljaka, a  to  dovodi  do  smanjenja  prinosa.  Cilj  ovog  rada  bio  je  da  se  istraži  efekat  suše  na  fiziološke  reakcije  biljaka  kukuruza  (IP3722),  koje  su  dobijene  iz  semena  različite  starosti  (regenerisano  2012. i 2016.) i različitih prethodnih iskustava (semena koja su formirana 2012. su bila u većoj meri izložena suši nego ona iz 2016.). Suša je kod oba uzorka dovela do smanjenja sveže i suve mase nadzemnog dela biljke, što je bilo praćeno opadanjem lisne površine i stomatalne provod-ljivosti. Tretmanom suše su indukovani hemijski signali (ABA i pH) i hidraulički signal (vodni potencijal), koji su uticali na provodljivost stoma. Podaci su pokazali da hidraulički signal ima podjednak udeo na zatvaranje stoma u tretmanu D2012 i D2016. Takođe, ABA kao hemijski signal dovodi do zatvaranja stoma, ali ovaj efekat zavisi od toga da li ABA potiče iz korena ili lista. ABA poreklom iz lista je imala značajniji doprinos u zatvaranju stoma kod  D2012, dok ABA poreklom iz korena i pH kod tretmana D2016.
