The research was conducted in April - May 2024 at the Screen house of the Center for the Application of Agricultural Instrument Standards, Banten. This research used a factorial randomized block design, the first factor was the mechanical scarification treatment on seeds (S), which consisted of 3 levels, namely without wounding (S0), sanding (S1), and piercing (S2). The second factor was the concentration of gibberellin treatment, which consisted of 3 levels, namely a concentration of 50 ppm (G1), a concentration of 75 ppm (G2), and a concentration of 100 ppm (G3). The results showed that mechanical scarification by sanding had the best treatment effect, namely on the parameters of the percentage of germination power (82.22%). The concentration of gibberellin solution with a concentration of 50 ppm offer the best effect, namely on the parameters of the percentage of germination power (77.77%) and the percentage of seeds that did not grow (22.22%). The results indicated that there was an interaction between mechanical scarification treatment and gibberellin level concentration of 50 ppm and 75 ppm on the parameters of germination power. date: 2024 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/44738/1/Regita%20Chintya%20Azzahra_4442200157_Fulltext.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/2/Regita%20Chintya%20Azzahra_4442200157_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/3/Regita%20Chintya%20Azzahra_4442200157_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/4/Regita%20Chintya%20Azzahra_4442200157_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/5/Regita%20Chintya%20Azzahra_4442200157_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/6/Regita%20Chintya%20Azzahra_4442200157_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/7/Regita%20Chintya%20Azzahra_4442200157_Ref.pdf format: text language: id identifier: https://eprints.untirta.ac.id/44738/8/Regita%20Chintya%20Azzahra_4442200157_Lamp.pdf identifier: Chintya Azzahra, Regita (2024) PENGARUH SKARIFIKASI MEKANIK DAN TINGKAT KONSENTRASI GIBERELIN TERHADAP PEMATAHAN DORMANSI SERTA PERKECAMBAHAN BENIH SAWO MANILA (Manilkara zapota L.).
