Scarification (botany)

Ịkpa ahụ n'ime ihe ọkụkụ na-agụnye ike ọgwụgwụ, imeghe, ma ọ bụ gbanwee uwe nke mkpụrụ osisi iji kwalite ịmị mkpụrụ. A na-emekarị ihe nfụkasị ahụ n'ụzọ igwe, thermally, na kemịkalụ. Mkpụrụ nke ọtụtụ ụdị osisi anaghị ebute mmiri na gas, si otú a na-egbochi ma ọ bụ na-egbu oge germination. Usoro ọ bụla e mere iji mee ka testa (uwe mkpụrụ) na-asọba na mmiri na gas ka a maara dị ka ịchafụ.

Scarification, n'agbanyeghị ụdị ọ bụla, na-arụ ọrụ site n'ịme ngwa ngwa usoro okike nke na-emekarị uwe mkpụrụ osisi na-agafe na mmiri na ikuku. Maka drupes (mkpụrụ osisi nkume), ịchafụ na-agbatịkwa ike ọgwụgwụ ma ọ bụ wepụ shei endocarp siri ike gburugburu mkpụrụ ahụ.

 Ụdị 
N'agbanyeghi usoro, mkpụrụ ndị a na-eme ka ha ghara ichekwa nke ọma ma chọọ ka a kụọ ha ngwa ngwa, ka mkpụrụ ndị ahụ ghara ịdị irè.

 Injinia 
Ụdị scarification a na-ahụkarị bụ scarification igwe.

Na scarification igwe, a na-emeghe testa ahụ iji kwe ka mmiri na ikuku banye. Enwere ike itinye uwe mkpụrụ osisi na faịlụ ígwè, jiri akwụkwọ ájá na-asacha ya, jiri mma na-asa ya, jiri hama na-agbaji ya nke ọma, ma ọ bụ mee ka ọ ghara ịdị ike ma ọ bụ meghee ya n'ụzọ ọ bụla ọzọ.

Enwere ike ijikọta scarification mmiri ọkụ na scarification kemịkal, mana ọ nwere ike ịchọ ihe nchebe megide gas ndị e mepụtara.

Hot water treatment is also used for removal of pathogens. Placing seeds in 90 °C for 90 seconds followed by dip in cold water for 30 seconds kills the human pathogens Escherichia coli O157:H7 and Salmonella. A variety of plant pathogens are also killed by hot water treatment.

 Okpomọkụ 
In some chaparral plant communities, some species' seeds require fire and/or smoke to achieve germination. An exception to that phenomenon is western poison oak, whose thick seed coatings provide a time delayed effect for germination, but do not require fire scarification.C. Michael Hogan (2008) Western poison-oak: Toxicodendron diversilobum, GlobalTwitcher, ed. Nicklas Stromberg 

 Chemical 
Chemical scarification na-emekarị na okike n'oge endozoochory - mgbe ụmụ anụmanụ na-eri mkpụrụ osisi na mkpụrụ osisi na acid afọ ha na-adị nro ma malite imebi testae, na-eme ka ha nwee ike ịbanye na mmiri. Mgbe a chụpụrụ mkpụrụ ahụ site na nsị, ọ bụghị naanị na a na-etinye ha n'ime nsị na-edozi ahụ nke osisi kamakwa ọ na-enwekwu ike - usoro nke ịmị mmiri dị mkpa maka mmalite nke ntolite.

Scarification aka na-agụnye iji otu ma ọ bụ karịa kemịkal iji ṅomie acid afọ nke anụmanụ na-eri mkpụrụ osisi iji kwalite ntolite. Ọ nwere ike ịgụnye itinye mkpụrụ n'ime acidic ma ọ bụ ihe ngwọta dị mkpa maka oge dịgasị iche iche. Enwere ike iji kemịkal dịka sulfuric acid ma ọ bụ ọbụna kemịkal ụlọ mee ihe iji metụta usoro a.
