Aia nā mea hoʻoponopono ulu ulu i nā ʻano he nui, kēlā me kēia me kāna kuleana kūʻokoʻa a me ka laulā o ka noi. Eia kekahi mau mea hoʻoponopono ulu ulu a me ko lākou mau hiʻohiʻona i manaʻo nui ʻia he maʻalahi a maʻalahi hoʻi:

ʻO nā mea hoʻoponopono ulu lāʻau (PGRs) he pūhui kemika i hoʻohui ʻia me nā hopena physiological like a me nā hana kemika like me nā hormones mea kanu endogenous. Aia ka mea hoʻoponopono ulu i ka ʻāpana ākea o nā pesticides a he papa ia o nā pesticides e hoʻomalu i ka ulu a me ka ulu ʻana o nā mea kanu, me nā pūhui synthetic e like me nā hormones mea kanu maoli a me nā hormones i unuhi pololei ʻia mai nā meaola.

ʻO Auxin ka indole-3-acetic acid, me ke ʻano mole mole C10H9NO2. ʻO ia ka hormone mua loa i ʻike ʻia e paipai i ka ulu ʻana o ka mea kanu. ʻO ka huaʻōlelo Pelekane mai ka huaʻōlelo Helene auxein (e ulu). ʻO ka huahana maʻemaʻe o ka indole-3-acetic acid he aniani keʻokeʻo a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. Hiki ke hoʻoheheʻe ʻia e like me ka ethanol a me ka ether. Ua maʻalahi ka oxidized a lilo i ʻulaʻula rose ma lalo o ke kukui, a ua hoʻemi ʻia kāna hana physiological. ʻO ka ʻakika Indole-3-acetic i loko o nā mea kanu i loko o kahi kūlana manuahi a i ʻole ma kahi kūlana paʻa (paʻa).

ʻO ka ʻokoʻa o ka hana: 24-epibrassinolide he 97% ikaika, aʻo 28-homobrassinolide he 87% ikaika. Hōʻike kēia i ka 24-epibrassinolide i ʻoi aku ka ʻoi aku o ka hana ma waena o nā brassinolides i hoʻohuihui ʻia.
