ʻO kēia mauʻu ʻohe a lāʻau paha? No ke aha e ulu wikiwiki ai ka ʻohe?

ʻO ka ʻohe, kekahi o nā mea kanu maʻamau i ko mākou ola, he kumu hoihoi. Ke nānā aku nei i ka ʻohe kiʻekiʻe a lohi, ʻaʻole hiki i kekahi ke haʻohaʻo, he mauʻu a he lāʻau paha kēia? No ka ʻohana hea? No ke aha e ulu wikiwiki ai ka ʻohe?

Ua ʻōlelo pinepine ʻia ʻaʻole mauʻu a ʻaʻole lāʻau ka ʻohe. ʻO ka ʻoiaʻiʻo, no ka ʻohana Poaceae ka ʻohe, i kapa ʻia ʻo "Bamboo subfamily". Loaʻa iā ia kahi ʻano vascular maʻamau a me ke ʻano ulu o nā mea kanu lāʻau. Hiki ke ʻōlelo ʻia he "ʻano nui o ka mauʻu." He mea kanu ka ʻohe me ka waiwai kaiaola, waiwai, a me ka moʻomeheu. Aia ma mua o 600 mau ʻano i loko o 39 genera ma Kina, ka hapa nui i kahele ʻia ma ka muliwai ʻo Yangtze a me nā panalāʻau a me nā ʻāpana hema o ia. ʻO ka laiki kaulana, ka palaoa, ka sorghum, a me nā mea ʻē aʻe, ʻo ia nā mea kanu a pau o ka ʻohana Gramineae, a he ʻohana pili loa lākou no ka ʻohe.

Eia kekahi, hoʻokumu ke ʻano kūikawā o ka ʻohe i ke kumu no kona ulu wikiwiki. He ʻohe ma waho a he hakahaka ko loko. ʻO ka maʻamau ka lōʻihi a me ka pololei. ʻO kāna ʻano internode kūikawā e hiki ai i kēlā me kēia internode ke hoʻolōʻihi koke. Hoʻomohala nui ʻia ka ʻōnaehana kumu o ka ʻohe a hoʻolaha nui ʻia. Hiki i kona aʻa ke komo koke i ka nui o ka wai a me nā meaʻai. Hāʻawi ka wai lawa i ka mana mau no ka ulu ʻana o ka ʻohe. Ma o kāna ʻupena aʻa nui, hiki i ka ʻohe ke komo pono i nā mea like ʻole e pono ai no ka ulu ʻana mai ka lepo. No ka laʻana, hiki i ka ʻohe pilikua Kina ke ulu a hiki i 130 kenimika i kēlā me kēia 24 hola ke ulu wikiwiki. ʻO kēia ala kūʻokoʻa o ka ulu ʻana e hiki ai i ka ʻohe ke hoʻonui wikiwiki i kona ʻano heluna kanaka a noho i kahi ākea i kahi manawa pōkole.

I ka hopena, he mea kanu kupaianaha ka ʻohe no ka ʻohana mauʻu a loaʻa iā ia nā hiʻohiʻona kūʻokoʻa e hiki ai ke ulu wikiwiki. ʻO kona maʻalahi a me ka hoʻomau ʻana e lilo ia i kumu waiwai no nā huahana like ʻole, me ke ʻano o ka pepa ʻohe. ʻO ka hoʻopaʻa ʻana i nā huahana i hoʻokumu ʻia i ka ʻohe hiki ke hāʻawi i kahi ola hoʻomau a ʻike i ke kaiapuni.
