<\/p>Fotosyntes<\/strong>Alla tr\u00e4d f\u00e5r sin energi ifr\u00e5n solens ljus genom att omvandla vatten och koldioxid till socker och ett \u00f6verskott av syre. F\u00f6r att g\u00f6ra detta anv\u00e4nder alla v\u00e4xter klorofyll. Klorofyllet finns i n\u00e5gra olika varianter som \u00e4r olika bra p\u00e5 att absorbera olika v\u00e5gl\u00e4ngder av solens ljus. Klorofyllet ger v\u00e4xten dess gr\u00f6na f\u00e4rg genom att huvudsakligen, men inte enbart, absorbera r\u00f6tt och bl\u00e5tt ljus. \n

<\/p>I och med behovet av ljus str\u00e4var alla v\u00e4xter upp\u00e5t. Vissa mer och andra mindre, vissa breder ut sig mer i sidled \u00e4n andra. Tr\u00e4dets v\u00e4xts\u00e4tt \u00e4r del av artens karakt\u00e4ristika och \u00e4r behov som du enklare jobbar med \u00e4n emot. Samtidigt \u00e4r ditt m\u00e5l som bonsaiodlare oftast att l\u00e5ta din bonsai efterlikna tr\u00e4d av samma art. \n

<\/p>Stammen b\u00e4r fotosyntesapparaten<\/strong>De v\u00e4xter vi odlar som bonsai har en vedartad stam och vedartade grenar. Stammen skyddas av ett barkskikt som genom vaxartade kemiska f\u00f6reningar skyddar vattnet p\u00e5 insidan fr\u00e5n att komma ut samt insekter, bakterier och virus att ta sig in. \n

<\/p>Stammen har tv\u00e5 huvudfunktioner. 1, att lyfta l\u00f6vapparaten s\u00e5 att den n\u00e5r solljuset. 2, att f\u00f6rmedla vatten och n\u00e4ring och vissa tillv\u00e4xthormoner fr\u00e5n r\u00f6tterna till ledarna och l\u00f6vverket samt f\u00f6rmedla energin i form av sockerarter fr\u00e5n bladen till r\u00f6tterna. \n

<\/p>F\u00f6r att kunna uppr\u00e4tth\u00e5lla fotosyntesen, skapa blommor och frukt m.m. s\u00e5 beh\u00f6ver v\u00e4xten f\u00f6rutom vatten ocks\u00e5 sp\u00e5r\u00e4mnen. I den lilla bonsai-krukan beh\u00f6ver vi d\u00e4rf\u00f6r regelbundet tillf\u00f6ra dessa i form av g\u00f6dning. N\u00e4ringen och vattnet sugs upp av r\u00f6tterna. \n

<\/p>Rotsystemet<\/strong>Vattnet sugs upp genom osmotiskt tryck. Genom att v\u00e4xten med sin fotosyntes bildar socker s\u00e5 \u00e4r vattenkoncentrationen mindre p\u00e5 insidan rottr\u00e5den \u00e4n p\u00e5 utsidan. Eftersom sockermolekylerna \u00e4r f\u00f6r stora s\u00e5 kommer de inte igenom det tunn cellskiktet. Under tiden \u00e4r det mer sannolikt att vattenmolekyler \u00e5ker fr\u00e5n d\u00e4r det finns mer vatten \u00e4n fr\u00e5n d\u00e4r det finns mindre. Detta bildar ett infl\u00f6de av vatten i rottr\u00e5darna. \n

The experiment above can be tested with a semi-permeable layer, such as old-fashioned sausage casing. Water molecules statistically tend to migrate more often from the side where the water concentration is higher. This phenomenon is known as osmotic pressure.<\/figcaption> \n<\/figure> \n<\/div> \n

<\/p>Genom att v\u00e4xten aktivt drar in kalcium, magnecium, kalium med flera positiva joner dras negativa joner spontant in i v\u00e4xten. V\u00e4l d\u00e4r inne bidrar de till att \u00f6ka det osmotiska trycket (ovan). \n

<\/p>F\u00f6r att r\u00f6tterna skall kunna genomf\u00f6ra sitt mycket viktiga uppdrag beh\u00f6ver n\u00e4ringskoncentationen h\u00e5llas p\u00e5 en lagom l\u00e5g niv\u00e5. Kommer f\u00f6r mycket n\u00e4ring p\u00e5 en g\u00e5ng blir salthalten p\u00e5 utsidan r\u00f6tterna f\u00f6r h\u00f6g och det osmotiska trycket orkar inte trycka upp vattnet i bonsaiens\/tr\u00e4dets krona, varf\u00f6r den vissnar och d\u00f6r. D\u00e4rf\u00f6r beh\u00f6ver du h\u00e5lla en l\u00e5g men stabil koncentration i krukan. \n

<\/p>En av de l\u00e4ttaste s\u00e4tten att g\u00f6ra detta \u00e4r genom att ha en jord som agerar jonbytare med vattnet och binder till sig de viktiga n\u00e4rings\u00e4mnena, men till\u00e5ter r\u00f6tterna att aktivt laka ur dem efter behov. \n

<\/p>F\u00f6r att r\u00f6tterna skall kunna jobba effektivt beh\u00f6ver de kunna andas syre. Det syre v\u00e4xten tillverkar sj\u00e4lv anv\u00e4nds ju av l\u00f6vverket sj\u00e4lvt och \u00f6verskottet l\u00e4cker ut i luften. S\u00e5ledes beh\u00f6ver r\u00f6tterna andas sitt eget syre under jord. F\u00f6rbrukningen \u00e4r inte s\u00e5 stor men absolut livsn\u00f6dv\u00e4ndig. \n

<\/p>F\u00f6r att kunna f\u00e5 syre s\u00e5 det r\u00e4cket beh\u00f6ver jorden vara v\u00e4ldr\u00e4nerad s\u00e5 att inte vatten blir st\u00e5ende i krukan. F\u00f6r mycket vatten dr\u00e4nker de \u00f6mt\u00e5liga rottr\u00e5darna. D\u00e5 slutar tr\u00e4det att ta upp vatten. \n
