Ke ola nei nā kumulāʻau Gingko no nā makahiki he mau makahiki ma o ka hoʻomohala ʻana i nā hana uku e mālama ai i ke kaulike ma waena o ka ulu a me ka ʻelemakule.
Ginkgo biloba, he lāʻau gymnosperm deciduous maoli no Kina i ʻike maʻamau ʻia ma ke ʻano he mea hoʻohui olakino a me ka lāʻau lapaʻau.
Ua ʻike ʻia hoʻi no ke ola lōʻihi loa.
Kekahi o ka ʻO Gingko ʻoi aku ka nui o nā lāʻau ma Kina a me Iapana ma mua o ke tausani makahiki. Ua ʻōlelo ʻia ʻo Ginkgo he mōʻalihaku ola. ʻO ia wale nō ka mea ola e hiki ke ola ma mua o 1000 mau makahiki me ka pale ʻana i ka ʻelemakule, ka waiwai nui loa o nā mea ola. No laila, ua kapa ʻia ʻo Gingko i kahi kokoke i ka make ʻole.
ʻO ka ʻepekema ma hope longevity ʻO ia mau lāʻau kahiko i makemake nui i ka poʻe loea noiʻi lōʻihi. ʻO kekahi o ia pūʻulu, ma hope o ka noiʻi ʻana i nā loli e pili ana i ka makahiki i ka vascular cambium mai 15 a 667 mau makahiki Ginkgo biloba lāʻau, ua paʻi i kā lākou ʻike i kēia manawa ma Ianuali 13, 2020 ma PNAS.
I loko o nā mea kanu, pili ka emi ʻana o ka hana o ka meristem (nā ʻāpana ʻokoʻa ʻole e hoʻāla ai i ka ʻiʻo) me ka ʻelemakule. I nā mea kanu nui e like me Gingko, ʻo ka hana o ka meristem i loko o ka vascular cambium (ka mea ulu nui i loko o nā ʻōpala) ke kumu.
Ua aʻo kēia pūʻulu i ka hoʻololi ʻana o nā waiwai o ka cambium vascular i nā kumulāʻau ʻo Gingko kahiko a me nā kumu cytological, physiological, a me nā molecular. Ua ʻike lākou ua hoʻomohala nā kumulāʻau kahiko i nā ʻano hana uku e mālama i ke kaulike ma waena o ka ulu a me ka ʻelemakule.
ʻO nā hana e pili ana i ka hoʻomau ʻana o ka māhele cell i ka cambium vascular, ka hōʻike kiʻekiʻe o nā genes pili i ke kū'ē, a me ka hiki ke hoʻomau i ka hana synthetic o nā metabolites pale lua i hana mua ʻia. Hāʻawi kēia haʻawina i ka ʻike i ke ʻano o ka ulu ʻana o ia mau lāʻau kahiko ma o kēia mau mīkini.
