Kanu'ōiwi nā hua pī (huahelu)

mau ano o nā'ōlelo hiki ke hōʻike 'ia ma ke kanu honua: asexual a me ka moe. Keʻano mua mai nā 'na ano o ka EYI o hereditary' ike, me ka pololei ke kelepona hele mahele, vegetative - ma ka pūʻulu o somatic keena, a me ka propagation o ka hana kūikawā haploid keena - spores. Ka lua, oi e holumua ai palapala - ia mea moe nā'ōlelo, e alakai ana i ka ho okumu ana o na anoano. Ua lŘlŘ i loko o ke ola kalapona o gymnosperms a me flowering mea kanu, i kapaʻia angiosperms. Ma keia pepa, ua noonoo ka mawaho 'ole o ka hua me ka pī, loaʻa mai i nā kūlana e pono no kona ulu, e like me ka hoʻoholo' ana i ia e pōmaikaʻi ai i na mea kanu hiki i ka poʻe mamo ma nā'ōlelo.

He aha a pehea ka anoano i hana?

Bean - thermophilic moʻomeheu makahiki legume ohana, ka mea, he pua ano kinona ua like no me ka hahai sailboat paha e noho ana me ka pelupelu ia mau eheu. Loko o ka pua i loko o kekahi ua hapa no ka mea, i kapaʻia ka pistil, i ke kumu o ka hua ua hūnāʻia ma lalo o kona iwi embryo sac. He He diploid oocyte a me ka 'ole, haawiia i like ke kikowaena halepaahao. Ka mea, kūpono fertilize mau sperm, kūpono ma, a he mea i ka hua o ka mohihi. He ka germ, me ka hapahā o ke aloha i huiʻia no ka ulu a me ka hoʻomohala o nā cotyledons, a me na veils, i kapaia ka hua kapa.

He aha e na anoano o dicotyledons

All flowering mea kanu a me nā cotyledons i hanaʻia e like me ka hopena o ka fertilization o ka hua me na anoano ma ke kahua o ka i a Mānoa i ka papa kuhikuhiE ua pâʻani 'o ia ma nā māhele o ka pua: calyx, corolla o petals, androecium oia hoi o stamens, a, o ka papa, a me ka pistil hua kumu. 'Ole ka hua me ka pī like i loko o ka 6th papa' ike lea i ke kālaimeaola pauku like botany. Ua loaʻa he ellipsoid kinona, i ke aloha no a he kilakila dala o semen ua hui me ka kŘpa a uukuʻilikai wahi.

Kēia hiʻona minimizes i ka hui 'ana o ka hua me ke kaiapuni. Ka mawaho 'ole o ka me ka pī hua kohu i ka papa kuhikuhiE excretory hui, nenoaiu i loko o mammals. Aia ka i ka ho'ākāka 'ana i loko o kanaka'anatomia - me ka pī-hoʻokino puʻupaʻaʻelua. Ma ka loko, ka concaveʻaoʻao o ka rumen mea - wahi me ka pī hua a ua pili i ka puapua hua maloo, me ka pī mahope. Nolaila i ka inoa o ka ohana laau - Legumes. He ua oi mamua o 12 tausani.? Ueo. Ka hapa nui o kona mau lala - herbaceous ano, aka, aia no kekahi laau uuku a me na laau. I waena o legumes kahea aku mooolelo no ka maʻiʻo o ka waiwai nō hoʻi kumuʻiʻo: ia mea soy, peas, ka papapa maka, papapa.

Hua 'ole, a me ko lakou ano

Mākou e hoʻomau i ka nānā i ka 'ole o ka hua mohihi. Ke Kii lalo, hōʻike i ke alo o ka hōʻike muaʻia aʻe māhele,ʻo ia ka hua kapa komo, elua cotyledons a me embryo ke aupuni 'therebetween.

Like i oleloia, ka mea ma waho hapa - peels ka hua - mea he hua germ derivative a lahilahi (integuments). Ua hanaʻia ka hana o ka hoomaluhia mai desiccation, loa ana wela a me nā adverse abiotic aʻe. O ka holo ana, no ka nui 'ole o ka hua embryo. No ke aha la keia mea ai, e ka ike ma ka lalo nei.

Embryo dicot

E like me mākou e hoomanao, ma ke kaʻina hana o ka papalua fertilization hoʻomaopop 'ana i wale flowering kanu, o ka fertilized hua - ka zygote - Hawaiʻi multicellular ho okumu. Ua ua kapaʻia he embryo, a he ekolu māhele: ka embryonic kumu, he ōhāhā a me ka plumule. E lohe i na kipi 'ole o ka me ka pī hua. Noaia ke aupuni 'hoi e hōʻike mai i ka embryo ua maluhia hunaia ma waena o cotyledons,' aʻole wale nō ka nui loa, akā, i ka loa ke kino a me ka kūlana 'ole. Next, e pane mākou i ka nīnau, i mea na mana hoʻomaopop 'ana i loko o ka walaʻauʻana eiiiiiaiou o ka embryo.

embryonic mole

Ka nui na dala o ka aina kanu i pono-ulu kumu'ōnaehana: i ka papa kuhikuhiE,ʻaoʻao a paranasal. Ka mauʻu, a me ka laau uuku laau? Ueony hiki ke hana mau 'ano o ka lola honua nā hale i mea botanically kapaʻia kāna mau' ōlelo a me ka fibrous aa nenoaiu. E like me ka mea huli mai, ka mea komo ma ka hooulu ana o ka hookahi hapa - ka embryonic kumu. E hoʻomaka ana kona aeea mahele i kanu physiology o ka papa kuhikuhiE ana ma i hoakaka hoʻomaka 'ʻano papa hana e like me ka hua germination. Ka papapa maka, nā komako, peas a me nā wela-puni, a kōkua aloha i ka wai ulu i kauoha mai i kaʻoi loa me ka hui pu ana o na? Aneie aʻe, no laila, i kēia kaʻina culminated i loko o ka muli o ka hou opiopio mea kanu.

Cotyledons a me kā lākou kūlana ma ka hiki 'ana o ka seedling

I mea e poʻe mamo hiki germinate i koi 'hookoe nutrient hui: pulapula o ke,'amino nāʻakika, bipi kūpaluʻia. Ma dicots ia i loaa i loko o nā cotyledons. I ke kakahiaka nui embryo germination ke aloha waiwai i loaa mai i ka mea hoʻoheheʻe palapala, loa i loaʻa no ka kaʻaluna ma keena. Ma seedling cotyledons o dicotyledonous mea kanu hoʻomaka e hana i kaʻoihana o ka honua mua, i ka ai-kapaia embryonic lau. Aka hoi, e hiki ke lawe mai kāʻamaʻai, a i ka bipi mea kanu a me nā mea a pau i ka mea e pono ai ea waiwai ka mea.

He aha ka ka germination o ka hua?

He He physiological kaʻina hana i ua ma muli o keʻano papa hana o ka hoʻololi mai i ka latent wā i loko o ke ola ana o ka hua i loko o kaʻeleu ulu ke kahua embryo māhele: aa, a kumu me ka lau. E like me ka hopena, i ka seedling mua 'ōili mai, a laila, ho okumu i'ōpiopio mea kanu. He aha ke ano o ka germinating me ka pī hua? Photos hooku iho la ia ma lalo pono hōʻike i ka mua hoʻomaka e hoʻomōhala i ka embryonic kumu, he ōhāhā a laila,ʻo ia ma luna o ka lepo cotyledon lau. Ma hope o kekahi mau manawa o ka ulu wahi o ke kumu, he o apical hoʻonaʻauao lole - meristem - hua mai la i ka oiaio, na lau me ka pī mea kanu.

Ke koena manawa

Ma hope o oo ana, e haawi ia ia e like me ka papapa maka, me ka pī anoano wa e ohi ai, mai ka mahina, eʻaʻole hiki iā koke germinate. 'Aʻole wale no legumes, akā, no hoi no nā pūʻulu, e like me nā komako, eggplants, kaʻukama, Pono manawa e kiʻi i ko lakou mau hua i Ua puka paha-e ohi ai oo ana. Ua Ua wehewehe aku kuhikuhi ma ka mea ia i keia manawa ma ka germ keena pūnao lawe mai ma ka loa haʻahaʻaʻilikai. Ha na anoano ua kokoke haliia mai la mawaho, i ka wai maʻiʻo mea emi ma mua o ke ono o ka huina kaumaha.

E like me kaʻilihune - na anoano e kupu palena iki ikehu lawa ole no ka hoololiia ana o ke aloha 'ona cotyledons ma wailana ano. Ua mawaho a me na 'ole me ka pī hua ma ka latency meaʻaʻoheʻokoʻa mai ia o ka vegetative wā mawaena ia ka mea, i hoomakaukauia e no ka lulu i ka lepo. Oko hai aku kuhikuhi i ke kahe ana o ka metabolic reactions i loko o ka halepaahao nucleus, i ka loa haʻahaʻa i loko o ka wā o ka dormancy.

He aha ka mea e pono ai ka germination o ka embryo

Ma ka agronomy ke hoomaopopo i ka ana ma lalo nei, e hōʻoia 'mea e like ai o ka hua germination a me ka seedling muli amicable: imua o ka wai, maikaʻi wela, o oxygen loaʻa nui, ka mea e pono ai ke hoʻomālamalama. E hoomanao i kēia mau kumumea i loko o hou au mamuli. Ka mua wahi ma luna o mākou papa inoa o abiotic aku ana ka wai. He mea pono i ka pehu keena, i ua pu ma ka hooikaika ana i ko lakou hanu.

Këia i ka 'ole o ka hua o ka papapa maka, ua loaʻa mai i ka mana o ka embryo mea hiki wale ina na ke aloha waiwai makana i loko o ka cotyledons, e hele i loko o pāʻoihana palapala. O ke kumu ho i ka wai nā lātoma, penetrating i loko o kā lākou pūnaewele parenchyma. E like me ka wela-puni ulu, ka papapa maka maikai pii ma ka pono la-mehana lepo. Akā, i ka malamalama, aole ia e pili i ka germination ikehu. No kaʻimi hoʻopunipuni? Aneii hua mai latent moku'āina ka mea, ua malamaia lakou nei, stimulants e like me phytohormones.

I hoʻomaka? Eaia scarification, oa mechanically loko i ka pono o kaʻili, me ā 'inoʻino kekahi o nā hale i nā wahi o ke kipi' ole o ka hua o ka papapa maka, ka oi aku o ka cotyledon a me ka germ. Penei, a pau o kēia mau mahiʻai hana hōʻeleu i ke germination kaʻina ulu.
