stdClass Object ( [id] => 1169961 [title] => Dr. Ivica Vlatković o fazama cvjetanja: Sorte krupnog ploda trebaju puno duža razdoblja niskih temperatura od sorti malog ploda [alias] => dr-ivica-vlatkovic-o-fazama-cvjetanja-sorte-krupnog-ploda-trebaju-puno-duza-razdoblja-niskih-temperatura-od-sorti-malog-ploda [catid] => 306 [published] => 1 [introtext] => [fulltext] =>

Prekid vidljivog rasta bilo kojeg dijela masline koji sadrži meristem struka naziva dormantnost. Smatra se da je dormantnost pupova prestala kad je 25-75% (obično 50%) pupova sposobno za rast, piše Maslina.

Indukcija cvatnih pupova je prvi stadij reproduktivnog ciklusa masline kada dolazi do prvog poticaja za tvorbu cvatnog pupa, a u biljnim tkivima nema vidljivih ili biokemijskih znakova koji bi se mogli odrediti.

Kod masline se indukcija cvatnog pupa događa ljeti.

Sljedeći stadij razvoja cvatnih pupova je njihova inicijacija. Inicijacija cvatnih pupova je stadij u kojemu se cvatni pupovi mogu identificirati histokemijskim ili biokemijskim testovima. Kod masline se to događa na prijelazu iz ljeta u jesen. I na kraju diferencijacija cvatnih pupova je razvoj dijelova cvijeta nakon inicijacije.

Kod mnogih voćnih vrsta umjerenog pojasa, cvatni se pupovi potpuno razviju prije zime, ali kod masline diferencijacija nastupa zimi ili na kraju zime.

Maslini je potrebno određeno razdoblje niskih temperatura da bi cvatni pupovi nakon indukcije nastavili s procesom diferencijacije. Pri tome svaka sorta ima različite vremenske sume subinaktivnih zimskih temperatura nižih od 7,2 Celzijeva stupnja.

Tijekom godina maslinarstva uočio sam da stolne sorte krupnog ploda (oblica, ascolana, dužica, uovo di picione...) da bi imale dobru oplodnju trebaju puno duža razdoblja prosječno niskih temperatura od uljnih sorti malog ploda.

Ako se dogode prodori hladnog polarnog zraka, kao 2012., 2016. i posebno 2018. godine, onda, uz velike štete na maslinama određenih područja, možemo očekivati obilan rod tamo gdje štete nije bilo, piše Maslina

Elezović je preporučivao
Po Elezoviću potpuno skidanje kore može se uspješno primijeniti na oblici, slivnjači, dužici i ostalim sortama krupnog ploda. Djelomično skidanje kore može se primijeniti na manje bujnim granama starijih stabala uljarica. Na mladim stablima uljarica može se primijeniti samo jednostruko zarezivanje.

Prekid vidljivog rasta bilo kojeg dijela masline koji sadrži meristem struka naziva dormantnost. Smatra se da je dormantnost pupova prestala kad je 25-75% (obično 50%) pupova sposobno za rast, piše Maslina.

Indukcija cvatnih pupova je prvi stadij reproduktivnog ciklusa masline kada dolazi do prvog poticaja za tvorbu cvatnog pupa, a u biljnim tkivima nema vidljivih ili biokemijskih znakova koji bi se mogli odrediti.

Kod masline se indukcija cvatnog pupa događa ljeti.

Sljedeći stadij razvoja cvatnih pupova je njihova inicijacija. Inicijacija cvatnih pupova je stadij u kojemu se cvatni pupovi mogu identificirati histokemijskim ili biokemijskim testovima. Kod masline se to događa na prijelazu iz ljeta u jesen. I na kraju diferencijacija cvatnih pupova je razvoj dijelova cvijeta nakon inicijacije.

Kod mnogih voćnih vrsta umjerenog pojasa, cvatni se pupovi potpuno razviju prije zime, ali kod masline diferencijacija nastupa zimi ili na kraju zime.

Maslini je potrebno određeno razdoblje niskih temperatura da bi cvatni pupovi nakon indukcije nastavili s procesom diferencijacije. Pri tome svaka sorta ima različite vremenske sume subinaktivnih zimskih temperatura nižih od 7,2 Celzijeva stupnja.

Tijekom godina maslinarstva uočio sam da stolne sorte krupnog ploda (oblica, ascolana, dužica, uovo di picione...) da bi imale dobru oplodnju trebaju puno duža razdoblja prosječno niskih temperatura od uljnih sorti malog ploda.

Ako se dogode prodori hladnog polarnog zraka, kao 2012., 2016. i posebno 2018. godine, onda, uz velike štete na maslinama određenih područja, možemo očekivati obilan rod tamo gdje štete nije bilo, piše Maslina

Elezović je preporučivao
Po Elezoviću potpuno skidanje kore može se uspješno primijeniti na oblici, slivnjači, dužici i ostalim sortama krupnog ploda. Djelomično skidanje kore može se primijeniti na manje bujnim granama starijih stabala uljarica. Na mladim stablima uljarica može se primijeniti samo jednostruko zarezivanje.

Dr. Ivica Vlatković o fazama cvjetanja: Sorte krupnog ploda trebaju puno duža razdoblja niskih temperatura od sorti malog ploda

Prekid vidljivog rasta bilo kojeg dijela masline koji sadrži meristem struka naziva dormantnost. Smatra se da je dormantnost pupova prestala kad je 25-75% (obično 50%) pupova sposobno za rast, piše Maslina.

Indukcija cvatnih pupova je prvi stadij reproduktivnog ciklusa masline kada dolazi do prvog poticaja za tvorbu cvatnog pupa, a u biljnim tkivima nema vidljivih ili biokemijskih znakova koji bi se mogli odrediti.

Kod masline se indukcija cvatnog pupa događa ljeti.

Sljedeći stadij razvoja cvatnih pupova je njihova inicijacija. Inicijacija cvatnih pupova je stadij u kojemu se cvatni pupovi mogu identificirati histokemijskim ili biokemijskim testovima. Kod masline se to događa na prijelazu iz ljeta u jesen. I na kraju diferencijacija cvatnih pupova je razvoj dijelova cvijeta nakon inicijacije.

Kod mnogih voćnih vrsta umjerenog pojasa, cvatni se pupovi potpuno razviju prije zime, ali kod masline diferencijacija nastupa zimi ili na kraju zime.

Maslini je potrebno određeno razdoblje niskih temperatura da bi cvatni pupovi nakon indukcije nastavili s procesom diferencijacije. Pri tome svaka sorta ima različite vremenske sume subinaktivnih zimskih temperatura nižih od 7,2 Celzijeva stupnja.

Tijekom godina maslinarstva uočio sam da stolne sorte krupnog ploda (oblica, ascolana, dužica, uovo di picione...) da bi imale dobru oplodnju trebaju puno duža razdoblja prosječno niskih temperatura od uljnih sorti malog ploda.

Ako se dogode prodori hladnog polarnog zraka, kao 2012., 2016. i posebno 2018. godine, onda, uz velike štete na maslinama određenih područja, možemo očekivati obilan rod tamo gdje štete nije bilo, piše Maslina

Elezović je preporučivao
Po Elezoviću potpuno skidanje kore može se uspješno primijeniti na oblici, slivnjači, dužici i ostalim sortama krupnog ploda. Djelomično skidanje kore može se primijeniti na manje bujnim granama starijih stabala uljarica. Na mladim stablima uljarica može se primijeniti samo jednostruko zarezivanje.
