\u00cen lunga serie de ani dedica\u021bi examin\u0103rii nutri\u021biei plantelor, s-a constatat c\u0103 nu doar macroelementele \u0219i microelementele sunt importante pentru culturile de plante, pentru cre\u0219terea \u0219i dezvoltarea lor, ci \u0219i aminoacizii, care se adaug\u0103 \u00een anumite fenofaze, \u00een func\u021bie de nevoile plantelor, precum \u0219i de condi\u021biile climatice care provoac\u0103 o stare stresant\u0103 la plante. <\/em><\/p>\n

\u00cen ultimii ani, am fost martori la schimb\u0103ri climatice extreme, \u00een special \u00een ceea ce prive\u0219te temperatura \u0219i umiditatea. Anul 2014 este amintit pentru ploile abundente \u0219i inunda\u021biile. De asemenea, oscila\u021biile de temperatur\u0103, pentru plante, \u00een fazele cele mai sensibile, au fost mari. Anul 2015 este amintit ca un an cu temperaturi extrem de ridicate \u0219i o perioad\u0103 secetoas\u0103, ceea ce a dus plantele la stres.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″ shape_divider_position=”bottom”][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][vc_column_text]\u00cen produc\u021bia intensiv\u0103 se cultiv\u0103 culturi cu randament ridicat, unde at\u00e2t calitatea, c\u00e2t \u0219i cantitatea sunt importante, ceea ce epuizeaz\u0103 \u0219i mai mult plantele.<\/p>\n

Indiferent dac\u0103 plantele sunt cultivate \u00een produc\u021bie intensiv\u0103 sau pentru nevoi proprii, cele aflate \u00een condi\u021bii meteorologice extreme \u0219i \u00eentr-o stare de stres au mai multe dificult\u0103\u021bi \u00een a reu\u0219i, dau randamente mai mici \u0219i lupt\u0103 doar pentru propria supravie\u021buire.<\/p>\n

Aminoacizii, ca parte integrant\u0103 a proteinelor, joac\u0103 un rol foarte important at\u00e2t \u00een \u200b\u200bconstruirea celulelor, c\u00e2t \u0219i \u00een procesele fiziologice \u0219i biochimice din celula vegetal\u0103.<\/p>\n

Exist\u0103 20 de aminoacizi care particip\u0103 la procesele fiziologice ale plantelor, iar fiecare dintre ei are propria func\u021bie specific\u0103.
