Abantu abadala, bezongena kwiingxaki zemihla ngemihla, bayeka ukubhala ingqalelo kwihlabathi elijikeleze, ngelixa abantwana bebamangaliswa imihla ngemihla ngempawu zayo. Yaye isebenza njani? Kwaye kutheni? Kwaye kutheni? Kwaye ke kuyimfuneko? Lona kuphela luthanda inxaxheba kule mihlaba encinci! Yaye ukuba unxiba isiqheno somama okanye utata, kungekudala emva koko uza kuwubuza umbuzo othi: "Kutheni amaqabunga ephendukile ewa?" Njengokuba umbuzo ngokwawo awunzima kakhulu, yenye yeempawu zekwindla , kodwa kuya kubakho uluhlu Okongeziweyo, okufuneka iphendulwe ngokucacileyo kwaye iyaqondakala. Ewe, makhe sizame ukwenza!
Kwaye kutheni amaqabunga aphendukile?
Ngentwasahlobo nakusihlobo kwiphepha ngalinye le-pigment chlorophyll lihlala, elinemibala eluhlaza. Ingumlinganiselo omkhulu we-chlorophyll eyenza amaqabunga emifino eluhlaza. Le ngulube iyadingeka ngumthi kungekhona nje ubuhle, kodwa ukutya okumnandi, kuba i-chlorophyll ingasebenzisa ukukhanya kwelanga ukuguqula i-carbon dioxide kunye namanzi kwisondlo. Ngoko, ngenxa yombala walo ohlaza okwesantwasahlobo, ukhula lukhula kwaye lukhula. Kodwa kufike ixesha xa uluntu lulungiselela ubusika, xa umsebenzi walo obalulekileyo unqunyanyisiwe, xa amaqabunga ephendulela okwenkantsha-oku kwenzeka ekwindla. Amaqabunga afumana amanzi amancinci, i-chlorophyll iya kutshabalalisa, kwaye izityalo zilahlekelwa ngumbala wazo oluhlaza. Kuyathakazelisa ukuba i-chlorophyll ibonakaliswe ngokutsha ngelilanga, ngoko ixesha apho amaqabunga aqala ukujibilika ekutshweni akuhlali kwenzeka ngexesha elinye. Kwikwindla eyomileyo, ecacileyo, amaqabunga aya kutshintsha umbala ngokukhawuleza, kwaye ekwindla kwemvula ahlale eluhlaza ixesha elide.
Kwaye kutheni ezo ziphuzi, kwaye zibomvu?
Umntwana otyhawuleyo uya kubuza ukuba kutheni amanye amaqabunga emithini ephuzi, amanye aphendulela obomvu, kanti amanye ajika emdaka. Impendulo ilula. Inyaniso kukuba ngaphezu kwe-chlorophyll, amaqabunga ezityalo aqulethe ezinye iingubo, kodwa ngenxa yobuluhlaza obuninzi abonakalayo. Njengoko i-chlorophyll eluhlaza ihlaziya, enye imibala ibonakala:
- Amaqabunga aphuzi athola umbala wabo ngenxa ye "umsebenzi" we-pigment xmenthophyll yesityalo;
- Amaqabunga e-orange agqoke kwiingubo zabo zekwindla, xa i-carotene ye-pigment ibonakala, leyo, ngendlela, iyaziwa kuwo wonke umntu ngombala obomvu wearrot;
- Amagqabi obomvu athola umbala ongalindelekanga ngenxa yeengulube ze-Anthocyanins;
- Amaqabunga amdaka - oku akukona umbala wee-pigments, kodwa umbala weendonga zeeseli zeqabunga, kubonakala xa ezinye iingubo ezibonakalayo zedayi zingekho.
Kwaye kutheni amaqabunga awela?
Ukuba sithetha ngolu hlobo lwenqabileyo yamacembe, i-mechanism iyacaca - ekwindla, xa amaqabunga ephendukile, uluhlu oluhlukileyo lwamaseli lubonakala kwisiseko seqabunga, okubizwa ngokuba yi-cork layer. Kancinci, le ntlukwano inqumla uxhulumaniso phakathi komthi kunye neqabunga. Ihlala ilinde ukuba umoya uvuthe kwaye iphepha liphantsi. Kwisebe kwindawo yechungechunge ushiya isiqhekeza esincinci esithintela ugcino olukhuselekileyo, oku kuthetha ukuba emthini kuyinkqubo engenakubuhlungu. Ukuba uyazibuza ukuba kutheni amaqabunga aphendukile kwaye awa,
