\u00cen trecut, merele erau mai mici, mai acre \u015fi mai amare dec\u00e2t \u00een \u200b\u200bprezent, \u00eens\u0103 se stricau mai repede \u00een timpul depozit\u0103rii. Zece tipuri de mere de baz\u0103 au fost studiate de cercet\u0103torii canadieni pentru a afla \u00een ce m\u0103sur\u0103 s-au modificat propriet\u0103\u0163ile lor din cauza cultiv\u0103rii de c\u0103tre om.<\/p>\n
Sean Myles, doctor docent \u00een \u015ftiin\u0163ele agriculturii la Universitatea Dalhousie din Canada, \u0219i echipa sa au lucrat \u00eentr-o livad\u0103 cu peste o mie de soiuri de mere, inclusiv soiuri str\u0103vechi ve\u0219nic verzi \u0219i mere s\u0103lbatice provenite din p\u0103durile Kazahstanului. Cercet\u0103torii au constatat c\u0103 m\u0103rul mediu cultivat ast\u0103zi este de 3,6 ori mai greu, este cu aproximativ jum\u0103tate mai acru \u0219i mult mai pu\u021bin amar dec\u00e2t speciile s\u0103lbatice din care deriv\u0103, scrie Sky News.<\/p>\n
\u201ePe baza \u00eensemn\u0103rilor istorice, am descoperit c\u0103 cultivarea de mere \u00een ultimii dou\u0103 sute de ani s-a \u00eendreptat spre m\u0103rul cu un con\u021binut mai mare de substan\u021b\u0103 uscat\u0103 solubil\u0103, mai pu\u021bin amar \u0219i mai pu\u021bin sensibil \u00een timpul depozit\u0103rii. Rezultatele noastre cuantific\u0103 schimb\u0103rile semnificative care s-au produs de la \u00eenceputul cultiv\u0103rii m\u0103rului, oferind dovezi c\u0103 \u00eencruci\u015farea diferitelor soiuri de mere a condus la diferen\u0163ierea \u00een continuare a merelor cultivate fa\u021b\u0103 de soiurile care cresc \u00een mediu s\u0103lbatic\u201d, au precizat cercet\u0103torii.<\/p>\n
Drept urmare, merele cultivate \u0219i cele s\u0103lbatice difer\u0103 \u0219i genetic, ceea ce se datoreaz\u0103 \u00eendrept\u0103rii aten\u0163iei, de sute de ani, asupra hibrizilor de specii.<\/p>\n
\u201eMerele care cresc \u00een mediu s\u0103lbatic ofer\u0103 material genetic poten\u021bial valoros care ar putea fi util pentru \u00eembun\u0103t\u0103\u021birea merelor\u201d, au spus speciali\u015ftii.<\/p>\n
Merele sunt unul dintre cele mai cultivate fructe din lume, cultivarea merelor dat\u00e2nd de cel pu\u021bin 7.000 de ani.<\/p>\n
