Asayansi ochokera ku Abilralturaci yaulirimaramication Sertivent of US Dipatimenting (Ar) kupanga kuyesetsa kupanga mitundu yatsopano ya matraberry, kugontheka kwa zipatso, ndi njira zachilengedwe zotetezera chikhalidwe.
Strawberries ndi chikhalidwe chamtengo wapatali ku USA, komwe nthawi yotsiriza ikukula mabulosi opangidwa. Pankhaniyi, ankhondo a ars adayang'ana chidwi chawo pakuchotsa mitundu yachilengedwe kuvunda kwachilengedwe ndikupereka zipatso zomwe zimatha kukhala zatsopano mukatha kukolola.
"Kusankhidwa kwa sitiroberi pabwalo lakale ku Beltsville, Maryland, amachitika kuyambira mu 1910, pomwe ofufuza athu adapeza momwe angasungire sitiroberi kapena kuzizira. Zomera za sitiroberi zopangidwa ndi dipatimenti yaulimi yaku US, m'malo mwake ndikukhala chiyambi cha magwiridwe a masitepe a dzikolo. Tsopano tikuyesetsa kugwiritsa ntchito mankhwala ophera tizilombo, pochotsa mbewu zokhazikika komanso kukhazikitsa matepi a New Kittics.
Ars imathandizira kulimbikitsa ukadaulo wokhala ndi mphamvu komanso thanzi la anthu kwa alimi azungu.
Fumium Wamkulu, wamaluwa - wofufuza tsopano, limodzi ndi anzanga ochokera kumandako, amapanga galimoto yomwe imafuna kufunika kwa mankhwala ophera tizilombo. Zipangizo zimagwira ntchito, kuwongolera ultraviolet (UV) Kuwala pa mbewu ndi tizirombo awo usiku.
"Mphamvu ya ultraviolet imapha tizilombo tating'onoting'ono tomwe timafotokozera, ndi a Arthropood tizirombo, kuwononga DNA yawo," adafotokozedwa ndi matayala. - Ultraviolet nthawi zambiri imagwiritsidwa ntchito kuwononga tizilombo toyambitsa matenda mu zipatala, maloborities, mankhwala othandizira madzi ndi zakudya za nyama.
Kugwiritsa ntchito kuwala kwa ultraviolet muzopanga kunali kochepa, chifukwa Mlingo wofunikira kuti chiwonongeko cha maluwa nthawi zambiri chimayambitsa kubzala mbewu, monga masamba owotcha ndi mawonekedwe ndi demors. Kafukufuku wathu anali ndi cholinga chopanga njira zovomerezeka zachuma pokonza ultraviolet, omwe amakhala ndi luso lothane ndi matenda ndi tizirombo osawonongeka kwa mbewu. "
Tarda ndi anzake adawona kuti kukonza kwa sitiroberi usiku kumawapatsa mwayi wogwiritsa ntchito ma radiation a ultraviolet kuwononga artively argoge ndi tizirombo, popanda kuwononga mbewu za sitiroberi. Zotsatira zake, famu ya eco-yochezeka imapezeka, yomwe imapereka zokolola chimodzi mwazomera za mabulosi am'mimba.
