Ko te Gibberellin he momo homoni tipu tetracyclic diterpene, ā, ko tōna hanganga taketake he gibberelline waro-20. Ko te Gibberellin, he homoni whānui-rahi e whakahaere ana i te tipu tipu o te tipu, he mea nui ki te whakahaere i te tipu o ngā puku tipu, rau, putiputi me ngā hua.
Te whakamahinga o te gibberellin
►Bwhakaroa i te moe o te purapura.
►Rwhakahaere i te tipu o te tipu.
►Cte whakahaere i te wā pua.
►Pte rerekētanga o te pua tāne romano.
►Fte tiaki i te pirau.
Ngā take o te pakaru o ngā hua
Ko te pakaru o ngā hua he āhuatanga o te kore taurite o te tinana o ngā tipu. Ko te take matua ko te kore e taea e te tipu o te kiri te urutau ki te tipu o te penupenu hua. E ai ki ngā rangahau me ngā whakarāpopototanga a ngā tohunga, ko ngā mea e awe ana i te pakaru o ngā hua ko: te pēhanga turgor i runga i te kiri, te tere tipu kore taurite o te penupenu me te kiri, te ngāwari o te kiri hua me te hanganga o te kiri hua. I roto i ēnei, ko te pēhanga pupuhi o te pericarp i pāngia e te wai me te ihirangi o te gibberellin me te waikawa abscisic; ko te kaha miihini o te pericarp i pāngia e te ihirangi konupūmā me ngā wāhanga pakitara pūtau; ko te toronga o te pericarp i pāngia e te ira whakangā o te pakitara pūtau. Ina kore taurite te pēhanga pupuhi, te kaha miihini me te toronga o te pericarp, ka puta te pakaru o ngā hua.
I te wā ua, ka nui rawa te wai ka pupuhi te kiri, ka pakaru ngā hua. I ngā marama maroke me ngā marama ua, ka tere ake te tupu o te hua i te kiri. Ina tae mai te wā ua, ka tere te mimiti o te wai me ngā matūkai e ngā tipu. Ko te kore taurite o te tere tipu i waenga i te hua me te kiripaka me te pikinga o te pupuhi o te kiripaka ka pakaru ngā hua. Mā te rehu hau ki runga i ngā hua tipu hei whakataurite i te pūnaha pēhanga o te kiri me te penupenu ka ārai i te pakaru o ngā hua.
I tēnei wā, e whakaatu ana ētahi tuhinga me ngā rēkoata whakamātautau he iti noa te pānga tahi o tēnei momo surfactant ki ngā kaiwhakahaere tipu gibberellin. Mā te whakanui matapo i te pānga tahi o ngā tāpiringa ka piki ake te utu o ngā kaiwhakatipu. Nō reira, e kī ana mātou me whakakotahi pūtaiao te huinga tika o ngā kaiwhakahaere tipu me ngā tāpiringa kia rite ki ngā āhuatanga me ngā hiahia o ngā huawhenua me ngā hua i ngā wāhanga tipu rerekē.
Bwhai hua
♦Mā te hanga kiriata i runga i ngā rau, i ngā hua rānei, ka whakaiti i te horoinga o te wai ua ki ngā wāhanga whai hua pēnei i ngā kaiwhakahaere tipu me ngā patu harore, ka karo i te whakamahinga anō, me te whakaiti i ngā utu.
♦Hangaia he paparanga tiaki pare-rā ki te mata o te rau me te mata o te hua, kia pai ai te whakaiti i te kino i puta mai i te hihi ultraviolet me te hihi o te rā i raro i te rā wera, ā, ka mahi hei raka wai me te ārai i te mimiti.
♦Whakatakotoria te pūnaha whakawhanui i waenga i te hua me te kiri kia kore ai e pakaru.
♦I muri i te rehu i te matū whakatipu tauanga hei whakapai ake i te tae o ngā hua, ka taea te rehu hei whakaroa i te wā e tukuna ana ngā hua.
♦Ka honoa ki ngā kaiwhakahaere tipu, ka whakaratohia he taurangi whānui mō ngā hua me ngā huawhenua i ngā wāhanga tipu rerekē.
