Pehea e hiki ai i kekahi ke hōʻike i ke kahe ʻana o kahi pua i hiki ʻole ai ia e pua

ʻO Ferns kekahi o nā lāʻau kahiko loa a ākea loa o ka lewa. Loaʻa i nā poʻe ʻepekema hou he ʻumi tausani o kā lākou mau ʻano i hiki ke loaʻa i nā lāʻau ʻino a me nā hoʻonaninani.

Kahi mua nā ferns ma ka Carboniferous manawa a uhi ʻia ka hapa nui o nā wahi marshy. Hiki ke loaʻa i nā ʻāpana o nā lau o kēia mea kanu ma nā ʻāpana o ka honi. Ma kēiaʻatikala e kamaʻilio mākou e pili ana i ka wehewehe ʻana o kēia mau mea kanu, a pili pū nō paha inā hiki ke hōʻoia ʻia hiki ʻole ke pua hiki ke pua.

Mahea e loaʻa ai nā ferns?

ʻO nā kūlana ʻoluʻolu loa no nā nahele he mau lāʻau ʻoihana, kahi e hōʻike ai kēia mau mea kanu i ko lākou ʻano āpau. Hiki iā lākou ke ulu i ka ʻāina wale nō, akā ma ka lāʻau a me nā pua o nā lāʻau.

ʻAʻole hika ʻo Ferns i nā nohona ola, no laila, ʻike pinepine ʻia ka mea i loaʻa i kēia mau wahi:

• pōhaku pili;
• kahiki;
• loko;
• nā alanui.

Kōkua ʻo Lianiform a me nā kumulāʻau lāʻau i nā wahiʻeleʻele, a ʻo ka mākaukau mau makahiki e kū ana ma hope o nā loko.

I nā anuanu huhū, hiki ke loaʻa nā mea kanu hakanima wale nō. ʻO nā mea maʻamau he mau ʻano o ka fern:

• ʻOstrich maʻamau;
• Kāne wahine a me Iapana;
• Kau kahiki kāne;
• Kanaka lehulehu;
• Nā lauwila o Scolopendra;
• ʻO Orlyak maʻamau.

Kākoʻo a me ke ʻano o ka fern

ʻOkoʻa ʻo Fern mai nā mea maʻalahi mai nā mea kanu maʻalahi i loko o kahi hoʻolālā ʻoi aku ka paʻakikī, kahi o ke kumu lāʻau, aʻa a me nā lau.

I nā huaʻai maloʻo, ʻōmaʻomaʻo ka ʻōpala, aʻo nā mea kanu lāʻau-like me ka nui o nā mea kanu me ka lei kiʻekiʻe ma luna.

ʻEhā hua ʻelua nā Rhizome i nā mea kanu mea i ʻelua.

1. Aia ka aʻa adnexal ma lalo, a ʻo nā lau ma luna;
2. Hoʻopili ʻia ka ʻili o ka rhizome i nā aʻa a me nā lau.

I kekahi mau ʻano o nā ferns, hiki ke loaʻa ka rhizomes i ka make.

ʻO nā lau he lau nui nui, akā aia nā hiʻohiʻona:

1. I ka awelika, ʻo ka lōʻihi o nā lau he 70-100 centimeter, akā akā ma ke ʻano maoli hiki iā ʻoe ke ʻike i nā specimens e hiki i kona nui ke hiki i 30 mika;
2. ʻO ke ʻano o ka pale ke koʻokoʻo a me ka pā laha me ka lāʻau paʻa;
3. Kūleʻa hou nā lau, ʻōleʻa pinepine nā lau ʻōpio. Ke hoʻomau nei ka ʻōlaʻi ma ʻō i ka wā lōʻihi;
4. Eia kekahi ma o nā hana nui, hiki i nā lau o kekahi mau ʻano ʻehā ke lawelawe e like me nā mea lawe no nā spora.

Ke ola kai o Fern

Hoʻolaha ka hoʻomake a Fern i nā ʻano spores, kahi i waiho ʻia ma nā lau pilikino o ka mea kanu.

ʻO ke kaʻina o ka nucleation o kahi mea kanu hou kahi penei:

1. I ka manawa pinepine, ʻike ʻia nā spores ma lalo o ka lau fern. ʻO nā wahi me nā nui o nā hua he nui i pili i kēlā me kēia, i kapa ʻia nā ʻehaʻehā, ma ka ʻano like me nā ʻeke liʻiliʻi;
2. I ka wā e pakeke a ka spora, hāʻule lākou a laha ma ka lewa;
3. Inā hāʻule ka mea kanu i ka nohona kūpono, a laila ulu ka pā lau liʻiliʻi mai ia, kahi i kapa ʻia he gametophyte a pili i nā hanauna o ka fern;
4. I kona nānāʻana, ua like kēia papa me ka puʻuwai, i hoʻopili ʻia i ka ʻāina e nā kaula milo - rhizoids;
5. Hoʻokumu ʻia nā gametes ma ka ʻaoʻao o ka ulu o ka mea i ulu, ʻo ia nā wahine (hua manu) a me nā kāne (sperm) formations;
6. Hoʻopilikia ʻia ka fertilization me ke kōkua o nā ua a i ʻole ka hau, e hāʻawi ana i ka sperm i ka ovum.

Ma muli o ka hoʻoulu ʻana, loaʻa kahi zygote, kahi i puka ai kahi sporophyte ma hope o ia, ʻo ia hoʻi ke ʻano o ka mea kanu. ʻO ia kekahi o ka gaustorium, ia like me ka wāwae ʻili e hoʻopili ʻia i kahi pua. Ma lalo o nā kūlana maikaʻi loa, ma hope o kekahi manawa, pono e kū pono ka lau lau mua, e ʻōlelo ana he kūleʻa ka hoʻolālā o kahi lāʻau hou.

Aia nā pūlani palahalulu ʻē aʻe e hoʻoulu ai i ka popen, kahi i loaʻa ai nā gametes. Hoʻokumu kēia mau ʻano i ka cones a ʻaʻohe mānaʻu.

Hiki paha, e kau ʻia ma ke ʻano o ke kumupaʻa, i mea e hoʻomoʻa ʻole ai ka pua?

No ka mea kanu he mea kanu kahiko, hiki iā ʻoe ke lohe i nā moʻolelo he nui e pili ana iā ia. ʻO ka mea e kaulana a hoʻowalewale mai iā lākou inā e ʻike ʻoe i kahi pua pua i ka pō o Ivan Kupala, a laila e hōʻike ʻia kahi mea huna a loaʻa ʻole i kekahi kanaka nā waiwai.

Akā inā e nānā i kēia nīnau mai kahi ʻanoʻike a me ka nānā ʻana i ke ʻano o ka fern, hiki iā ʻoe ke hele i ka hopena i hiki ʻole ke pua. Hōʻike pū ʻia kēia ma ka olakino olakino o ka mea kanu.

Pehea e hōʻoia ai ʻaʻole hiki i ka pua?

No ke aha lā ʻaʻole e pua iki ai? Ma ka nānā ʻana i ke ʻano o ke kumu o ka aʻai, hiki iā mākou ke ʻōlelo i ka hiki ʻole o ka pua ma kēia mea kanu no ka mea hoʻolaha ʻia e nā pua, ʻaʻole nā ​​hua.

I kona helehelena me ka pua, ua like nō ia me nā mea kanu pua, akā ʻo ka mea maoli he nui nā mea maʻamau me nā mosses, a ʻo ia hoʻi no nā mea kanu maʻalahi.

ʻO Fern ke nani a me nā pua ʻōmaʻomaʻo nui e ulu nei ma nā ululāʻau ʻōmaʻomaʻo, akā, ʻaʻole naʻe, hiki ʻole ke ʻike ke hiki i kāna pua.
