Yintoni ixesha lokufota?

Izityalo, njengezinto eziphilayo, zixhomekeke kwizikhuthazi ezininzi ezibanceda ukuba "bazi" into amabayenze nendlela yokwenza ngawo onke amaxesha. Umzekelo, xa iqala ukuphola, imithi enqabileyo iyayeka ukondla amagqabi, kuba ngekhe iphile kwiqabaka.

Kodwa into iya ngaphaya kokwazi xa ilixesha lokuphumla okanye lokuqalisa kwakhona ngomsebenzi. Ngapha koko, inani leeyure zokukhanya liya kugqiba, ubukhulu becala, xa izityalo kufuneka zenze umsebenzi wazo ngamnye. Le nkqubo yaziwa njenge ixesha lokufota, kwaye ibalulekile kuzo zonke izityalo.

Yintoni ixesha lokufota?

Ixesha lokufota iseti yemisebenzi eyenziwa zizityalo kuxhomekeke nokuba kusemini okanye ebusuku, lixesha lonyaka kwanomjikelo welanga. Ngamanye amagama, umahluko kwinani leeyure zokukhanya, kunye nexesha kunye nexesha, zizinto ezinefuthe kulawulo lokuhluma kwezityalo kunye nokukhula.

Ngesi sizathu, kumahlathi afumileyo akweleenjiko uninzi lwezityalo zihlala ziluhlaza, kuba amaqondo obushushu ahlala ezinzile unyaka wonke, kwaye imvula ine rhoqo.

Kwelinye icala, kwimimandla apho kubhaliswe khona iqabaka kunye / okanye imbalela, mininzi egxekayo: eminye kuba inamagqabi anokufa ukuba ebengagqunywe ngumkhenkce okanye likhephu; Abanye ukunqanda ukomisa (ukugcina amagqabi kubandakanya indleko enkulu yamanzi, ethi, ukuba ubushushu nembalela zidityanisiwe, kulindelwe ukuba isityalo sinxanwe, kuba into exabisekileyo iza kulahleka ngokukhawuleza. banamanzi amancinci abaza kuwadinga, kwaye kokuncinci baya kuphulukana nawo).

Ulibona njani ixesha lokufota?

Izityalo ineefotoreceptor ezineseli ezibuthathaka ekukhanyeni, eziguqula amandla ombane abe ngumbane. Zimbini iintlobo: i-phytochromes, eziziiproteni ezisebenza njenge-photoreceptor zokukhanya okubomvu kunye nokukhanya okubomvu okude; kunye nee-cryptochromes, zezo zibona ukukhanya okuluhlaza okwesibhakabhaka.

Xa besenza, qalisa uthotho lwemisebenzi, kuxhomekeke kuhlobo lokukhanya abakufumanayo. Ke, ngelixa ii-phytochromes zibangela ukuveliswa okanye ukuthintelwa kweentyatyambo, i-cryptochromes ilawula ukuntshula kwembewu kunye nokukhula, ukongeza kwisingqisho se-circadian, oko kukuthi, ukwahluka ngokuhamba kwexesha kweenkqubo zebhayoloji ezenzeka kwizityalo. (Nakwizilwanyana).

Enkosi koku, singazibeka ngokusekwe kwindlela abasabela ngayo kwixesha lokufota. Umzekelo, siyazi ukuba kukho izityalo ezineentsuku ezimfutshane, iintsuku ezinde kunye nezinye ezingaphenduliyo kwixesha lokufota kwaye zaziwa ngokungathathi cala. Iimpawu nganye yazo zezi:

• Izityalo zosuku olufutshane: ezi zezona zidinga ukuba ubusuku bube ngaphezulu kuneentsuku ukuze zikwazi ukudubula. Eminye imizekelo ngumbona, coffee, poinsettia okanye sitrobheli.
• Izityalo zemihla emide: ezi zezinye ezifuna iiyure zokukhanya ezingaphezulu kobumnyama ukuze zikwazi ukudubula, ezinje ngecarnation, oats okanye inkampu.
• Izityalo ezingathathi cala ngemini: ezi ziqhakaza ngexesha elithile kuphuhliso lwazo, okanye emva kokuvezwa, umzekelo, ixesha lamaqondo obushushu asezantsi. Eminye imizekelo zii-rose bushes, iitumato okanye amathanga.

Yintoni na?

Zonke izityalo, ekubeni ziyimbewu kuphela, zixhomekeke kwizikhuthazi ezininzi eziya kugqiba ngobomi bazo. Kuxhomekeka ekubeni ziimfutshane, zide okanye azithathi cala, kunye nohlobo lokukhanya olufunyanwa ngabafoti babo bokufumana iifoto, baya kwenza imisebenzi ethile okanye abanye.

Kungenxa yoko, Xa i-photoreceptor yesityalo seentsuku ezimfutshane ifumanisa, masithi, ukukhanya okubomvu, into eza kwenzeka ngaphakathi kubo kukuba ayizukuvelisa iintyatyambo.; Kwelinye icala, ukuba ukukhanya kubomvu kakhulu, isiphumo siya kubuyiselwa umva. Kulawo aneentsuku ezinde, iifotoreceptor zokukhanya okuluhlaza linoxanduva lokulawula ukuveliswa kweentyatyambo, kodwa isiphumo sinye.

Ngaba ixesha lokufota linokulawulwa?

Kwindalo, izityalo ziyayazi into ezakwenziwa ngawo onke amaxesha. Benza oko ukusukela oko baqala inguquko, ngaphezulu kweminyaka engama-300 yezigidi eyadlulayo, kwaye kuyathenjwa ukuba iya kuqhubeka injalo ngonaphakade. Kodwa abantu bafuye izityalo ezininzi; Oko kukuthi, sifunde ukubahlakulela ukuze singenelwe kubo. Ukusukela oko kwaveliswa izindlu zokugcina izityalo, kwaye kamva iibhalbhu ezikhuthaza ukukhula kunye / okanye ukudubula kweentyatyambo, sikwafunda ukulawula ixesha lokuthatha izityalo.

Nangona ekuqaleni kwakusenzelwa ukuba nokutya unyaka wonke, ngoku kuyenziwa nokukhawulezisa inkqubo esiyithandayo., umzekelo ukuze zibahle ngenyanga ethile (njenge mzantsiweb, Esiyi shrub esiyinyanzelayo ukuba sityatyambe, Oko kukuthi, sisuse iibracts zayo ezibomvu, ngeKrisimesi).

Eyona nto inomdla kukuba asidingi nto ingako ukulawula ixesha lokufota. Ukuqhubeka nomzekelo we-poinsettia, ebusika kuya kufuneka uyibeke kwindawo apho ilanga lingakhanyisi ngqo kangangeeyure ezilishumi elinambini, kwaye apho likwiqondo lobushushu elimalunga ne-20ºC, ude ulibone lidubula.

Inqaku elidibeneyo:

Ungawabuyisela njani ebomvu amagqabi ePoinsettia

Kwaye ukuba into oyifunayo kukuqhubela phambili ixesha lesityalo, ungahlwayela imbewu yayo kwi umvelisi zombane. Ngale ndlela, unokuvuna iiletesi, umzekelo, ngaphambili kakhulu kunokuba bekulindelwe.
