Mefuta le Mekhoa ea Ts'ebetso ea Maemeli a Tloaelehileng bakeng sa Paballo ea Lipalesa le Litholoana Merohong.

(I) Balaoli ba Khōlo ea Limela

1. Li-Auxins

(2,4-D), 4-CPA. Liemeli tsena li sebetsa ka ho etsisa li-auxin tsa semela, ka hona li khothalletsa ho hola le ho arohana ha lisele, ho matlafatsa tšebetso ea metabolic ka har'a ovary, le ho susumetsa parthenocarpy (popeho ea litholoana tse se nang peo). 2,4-D e bonts'a ts'ebetso e phahameng ea baeloji 'me hangata e sebelisoa bakeng sa meroho ea solanaceous joalo ka tamati le li-eggplant; leha ho le joalo, ts'ebeliso ea eona ea ts'ebeliso e tlameha ho laoloa ka thata (ka tloaelo 10-20 mg/L bakeng sa tamati), kaha ho tsepamisa mohopolo ho feteletseng ho ka lebisa ho senyeheng ha litholoana habonolo. 4-CPA e fana ka boemo bo phahameng ba polokeho 'me e loketse ho sebelisoa mefuteng e mengata e fapaneng ea meroho, ho kenyeletsoa tamati, likomkomere, le pelepele, hangata ka bongata ho tloha ho 25 ho isa ho 50 mg/L.

2. Li-Gibberellins

Gibberellic Acid (GA3) e khothalletsa ho lelefatsa lisele le ho senya boroko, kahoo e eketsa sekhahla sa ho beha litholoana. Temong ea morara, ho sebelisa GA3 (50 mg/L) nakong ea palesa ho ka khothalletsa ho holisa monokotšoai le ho fokotsa ho hola ha kutu (ho thatafala ha lehlaka la litholoana). Bakeng sa fragole, ho fafatsa GA3 (5-10 mg/L) nakong ea lipalesa ho potlakisa ho lelefatsa ha peduncle le ho ntlafatsa katleho ea ho tsamaisa peo.

3. Li-cytokinins

Mehlala e kenyelletsa 6-Benzylaminopurine (6-BA) le Forchlorfenuron (KT-30). Mahlahana ana a khothalletsa karohano ea lisele, ho liehisa senescence, le ho eketsa palo ea lisele tse ka har'a tholoana. Forchlorfenuron e sebelisoa haholo ho mahapu le mahapu, moo e khothalletsang haholo ho atolosoa ha litholoana; leha ho le joalo, kopo e sa nepahalang e ka fella habonolo ka litsi tse sekoti kapa ho se sebetse hantle ka har'a litholoana.


(II) Lintho tsa Phepo

1. Manyolo a Boron

Boron e bapala karolo ea bohlokoa ho hlahisoeng ha lintho tsa pectin ka har'a mabota a lisele tsa semela mme e khothalletsa ho mela ha peo e phofshoana le ho lelefatsa peō ea peō. Khaello ea boron e lebisa ho nts'etsopele e fokolang ea litho tsa lipalesa le ho fokotsa ho sebetsa ha peo e phofshoana merohong, e leng ho bakang ho theoha ha lipalesa le litholoana. Ho fafatsa tharollo ea 0.1% -0.2% ea borax kapa boric acid nakong ea lipalesa ho ka eketsa haholo litekanyetso tsa ho beha litholoana tsa meroho e kang tamati, likomkomere le linaoa.

2. Manyolo a Calcium

Calcium e tsitsisa mearo ea lisele le ho matlafatsa ho tiea ha litholoana le ho hanyetsa khatello ea maikutlo. Mathata a ’mele—a kang ho bola ha lipalesa ka har’a tamati le pelepele—a amana haufi-ufi le khaello ea k’halsiamo. Tšebeliso ea foliar ea 0.3% -0.5% ea calcium chloride kapa calcium sugar alcohol solution nakong ea ho beha litholoana ho ka thibela mafu a joalo ka katleho le ho lelefatsa sethala sa bophelo ba litholoana.

3. Manyolo a Phosphorus le Potassium

Phosphorus e kenya letsoho metabolism ea matla a limela 'me e khothalletsa ho arohana ha lipalesa; potasiamo e ntlafatsa ho hanyetsa khatello ea kelello ea semela le ho ntlafatsa bokhoni ba ho tsamaisa lihlahisoa tsa photosynthetic ho litholoana. Tšebeliso ea foliar ea 0.2% -0.3% monopotassium phosphate solution e ka matlafatsa haholo bokhoni ba ho thunya le ho beha litholoana tsa meroho.


(III) Li-Biostimulants

1. Li-extracts tsa Seaweed

E ruile ka lintho tse sebetsang tse kang polysaccharides, metsoako ea phenolic, le lilaoli tsa kholo ea limela, li-extracts tsena li matlafatsa ho hanyetsa khatello ea limela le ho khothalletsa phapang ea lipalesa le nts'etsopele ea litholoana. Liphuputso li bontšitse hore ho sebelisa monontsha oa foliar o nang le alginic acid nakong ea palesa ea likomkomere ho ka eketsa sekhahla sa ho beha litholoana ka 15% -20%.

2. Li-Humic Acids

Metsoako ena e ntlafatsa sebopeho sa mobu, e khothalletsa nts'etsopele ea metso, 'me e matlafatsa matla a semela bakeng sa ho amohela limatlafatsi. Ho feta moo, li-humic acid li laola ho leka-lekana ha li-hormone tsa limela, kahoo li ntlafatsa ho bolokoa ha lipalesa le litholoana lijalong tsa meroho.
