Ohana o ka mea kanu

Complex luna kiʻekiʻe taxonomy o? Ueo mai nā 'he nui nā waeʻano. kanuʻohana nō ma lalo o ka mokuna (mea) a kiekie ae like. Ko lakou mau inoa i hana ia e like me na rula, a i na na e International Code o Kāhua Ulu'lāʻau Nomenclature. Plant ohana ka inoa ua i hanaʻia ma ka pepa i ka inoa kumu o keʻano genus maʻamau panina -aceae. Ke'ōlelo mai, no ka laʻana, i hanaʻia ma ka inoa o ka ohana Rosaceae (Rosaceae), a he o ka genus inoa «Rosa», ma ke kumu o ka a lawe Ros- hou, a pau -aceae. I ka 'epekema Mea Maluna ua i kekahi manawa, hoʻohana' ia nā mea loaʻa papa: subfamily a me ka superfamily.

mea kanu o kaʻohana i loko o ka laekahi 'ano i waho ma ke kakahiaka nui XX kenekulia. No ka mea manawa mua kēia waeʻano i hoʻolauna i ka botanist Per Manol mai Farani hoʻi i loko o 1689. Over o ka makahiki, e ho he pūʻulu o loa okoaʻano. Kēia hana o ka hoʻohana 'ana i kēia inoa i pau wale i ka 1906 me ka hookamaia o kūwaho hoʻi rula o Kāhua Ulu'lāʻau nomenclature. E like me na rula, keia inoa i hele mai i ka olelo i kekahi mea i mua haawiia keia i na kauoha ma Roma paha ohana - i loko o Palani.

I loko nō o ka 'ano o nā mea kanu, he mea pono e kaulana i kekahi mea hou like i kekahi i kekahi, a me kekahi mau - emi. Kēia similarity ua nānā 'ana i ka pilina o kēia mau mea kanu. It nā laha 'i ke kumu o ke kahua o nāʻohana. Ua Ua ea ae ia ma keia Honua, aia nō ma luna o 350.000 laha 'o nā mea kanu:

- E lulu aku hoi ka limu: i 1,3 tausani hanau a me 25 tausani? Ueony; ..

- Fern o 300 genera a me 11 tausani? Ueo ;.

- Horsetail: 1 genus, a ma kahi o 25? Ueony;

. - lycopsids: 4, a 1 tausani ano o ka? Ueo;

- gymnosperms: 60 genera a me 700? Ueony;

- angiosperms (flowering): oi ma mua o 500 mau ohana, ma kahi o 13 tausani genera, a oi aku mamua o 250 tausani? Ueo ...

Aia nā mea kanu o ka 'ohana a pau loa hoihoi i loko o kanaka ma ka hua'ōlelo o ko lākou mau pono ma ka maʻamau o ke ola. Me kēia mau mea kanu 'ike, ua hiki ole i ke kanaka ke ola i loko o mau, no ka mea, he nui no ia e i ka nui loa o konaʻai. Kekahi o ka loa e like me ka mea i kaʻohana o dicotyledonous mea kanu. Ano helehelena o ka mea kanu i: ka alo o nā cotyledons; helu o kekahi mau oihana mua o ka holomoku pua lākou helu, ua like ia paha kekahi mau o ka 4 a me ka 5; ke aupuni 'annular lawelawe lole. Ka mole nenoaiu o kēia mau mea kanu i ka hapanui kookoo. Keia ohana ua poe ma nā 'ano apau loa o ke ola. Mawaena o na dicotyledons loaʻa nā lāʻau ikiʻai, laau uuku a me na laau. Kēiaʻohana mea e pili ana i 4/5 o flowering mea kanu ma ka Honua.

Mea kanu o ka legume ohana e pili ana i ka papa o ka bipartite. Kēia mea he nui loa nui? Ueo. Flowers i kona 'elele i haku o dissimilar petals 5, i ka ole kinona, 10 stamens. leguminous hua characteristically hooponopono. Kā lākou mea ua kapaia he Kāhua Ulu'lāʻau makahiki "me ka pī". A e like me ka hiʻona o ka hanauna o ka hoʻokahi-kau ovary, i ua ole puunaueia i kekahi, a me ka hua o nā mea kanu polyspermic, hahai. Oo ka hua ua hikiʻana mai ma na nakaka nā pā, e i i i pili i ka anoano.

Bean i kahi o 6,6 tausani.? Ueo a me 200 genera. Ka mea, i hohola aku nā mea a pau ma luna o ka Honua. Keia ohana Ua maheleia i subfamilies caesalpinioideae, mimosa, legumes. Ma hope buke i ka nui helu o nā mea kanu i loko o ka 'ohana. Kekahi o ia mea i ka loa nui kanakaʻai: ka papapa maka, papapa, peas, chickpeas, peanuts, soybeans. Na hua o kēia mau mea kanu i he kiʻekiʻe ka maʻiʻo o kaʻai kumuʻiʻo, he nui nā minelala hao a me nā wikamina. He nui o ia i hoʻohana i ka waiwai i ai no na holoholona: clover, vetch, sainfoin, clover, alfalfa. Herbaceous 'elele legumes hiki ia oe e extract naikokene mai o ka lewa, i ka nui mea kanu, a i hoʻohana no ka aina reclamation.
