Ruwa danshin shuka kwayoyin

Ruwa danshin ko transpiration, - wannan ne mai matukar muhimmanci na rayuwa da shuka. Ruwa da ake tunawa da tushen tsarin tare da narkar da ma'adanai da suke da muhimmanci ga al'ada girma da kwayoyin. Mafi yawa daga cikin tunawa ruwa evaporates ganye.

Da muhimmancin ruwa a cikin shuka jiki ci gaba. Ruwa - mai da muhimmanci sosai kashi da ta rawa a cikin rayuwa da shuka da wuya a overestimate. Saboda da ruwa goyon bayan turgor na sel, yin ganye da kuma mai tushe ne m da resilient. Ba tare da isasshen ruwa shuka da sauri fades.

Bugu da kari, tare da ruwa tunawa da tushen da ma'adanai an rarraba wa dukan gabobin da shuka. Danshi kuma kare jiki daga zafi fiye da kima. Danshin ruwa da shuke-shuke faruwa yafi ta hanyar da stomata - musamman samuwar kan ganye. A wasu awo transpiration ne da za'ayi da kuma duk kan shuka ta hanyar da sutura masana'anta.

Stomata da su tsari. Danshin da ruwa ganye auku farko ta hanyar musamman tsarin da ake kira stoma. Stomata kunshi biyu matsara Kwayoyin jinjirin wata siffar, tsakanin wanda akwai kananan rata. A ciki bango matsara Kwayoyin ne thicker da kuma m - bakin ciki. A karkashin tsarin ne a kananan rami.

Stomata suna located a garesu daga cikin takardar. Amma da yawa shuke-shuke suna located in na ciki na da shi. Amma a ruwa shuke-shuke, ganye suna tuntube da ruwa (msl, ruwa Lily), - a kan m gefen ganye.

Shi ne ya kamata a lura da cewa stomata ne alhakin ba kawai ga danshin ruwa, amma kuma ga gas musayar tare da yanayi - ta hanyar su ne oxygen da kuma carbon dioxide.

Danshin ruwa: yana daukan wuri? Kamar yadda aka ambata riga, transpiration iya faruwa ta hanyar maida hankali ne akan dukan shuka jiki jiki - a cikin wannan harka shi ne ake kira cuticular. A ganye, mai tushe, da sauran gawawwakin matasa shuke-shuke an rufe tare da guda Layer na epidermis - ta hanyar da shi, kuma a can ne danshi kau. A mafi balagagge shuke-shuke a cikin matsanancin surface na ball da aka ajiye da kakin cuticle cewa kare kwayoyin daga matsananciyar asarar danshi da bushewa fita. Saboda haka, cuticular transpiration a balagagge ganye rage zuwa m.

Main danshin wuce da shi ta hanyar da stomata. Don fara da ruwa motsa ta hanyar da xylem tasoshi, sa'an nan motsa a kan cell ganuwar cikin intercellular sarari inda podustichnye tattara a cikin kogo.

Bude da kuma rufe na stomata ne da farko rinjayi da yawan ruwa. Lokacin da danshi accumulates a matsara Kwayoyin, suka budewa da kuma dauki wani nau'i na jinjirin wata - a cikin wannan harka a rata yana buɗewa. Idan bai isa ba ruwa a cikin sel, suka rasa turgor, su ganuwar fada saukar da rufe tsaguwa.

Jihar na da stomata sakamako da kuma carbon dioxide ciki. Idan matakin a cikin tsokoki na shuke-shuke plummets, da matakai na stomata bude kunna. A at ma high maida hankali na gas rata rufe. Wannan shi ne dalilin da ya sa stomata aka rufe da dare, a lokacin da matakai na photosynthesis tsaya a nan ba.

Danshin ruwa da ta gwada yawa halaye. Kamar wani tsari, transpiration yana ta gwada yawa Manuniya, wanda ake amfani da su a da aikin noma, kimiyya da kuma sauran duniyoyin da rayuwar dan Adam.

Alal misali, transpiration kudi ya nuna yadda mutane da yawa grams na ruwa kasaftawa zuwa takamaiman ɓangare na shuka yanki da naúrar lokaci. By aunawa da yawan aiki na transpiration, yana yiwuwa ya ce nawa da bushe nauyi da shuka da aka tara a lokacin da danshin na daya kilogram na ruwa. A fassara wadannan Manuniya, yana yiwuwa a sami wasu mutum halaye na shuka iri, don kafa yanayi da zama dole domin ta m girma.
