PEMANFAATAN PARAMETER CHLOROPHYLL-A FLUORESCENCE UNTUK SELEKSI KLON KARET TAHAN KEKERINGAN
نویسندگان
چکیده
Chlorophyll-a fluorescence adalah perpendaran cahaya yang dilepaskan oleh klorofil untuk membuang kelebihan energi foton diterima dari sinar matahari pada proses fotosintesa. Salah satu parameter turunan chlorophyll-a Performance Index (PI). PI menggambarkan informasi kualitatif mengenai kebugaran tanaman. Pengamatan saat kondisi normal, tercekam kekeringan moderat, dan parah memungkinkan penghitungan nilai Drought Factor (DFI). Nilai DFI tingkat ketahanan tanaman terhadap cekaman lingkungan, termasuk kekeringan. Semakin tinggi DFI, semakin tahan tersebut lingkungan sebaliknya. Parameter telah berhasil dimanfaatkan menyeleksi genotip wijen, kacang arab, barley, sawit, karet. Penentuan sangat berguna kegiatan seleksi awal klon karet dapat menghemat waktu biaya harus dikeluarkan program pemuliaan

متن کاملChlorophyll Fluorescence: A Novel Method to Screen for Herbicide Resistance
The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rates...

Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m in TxS240 to 4320 mg m in Simmonds. Chlorophyll a/b ratio (Chl a/b) ranged from 9.8 to 5.5 in TxS238 and TxS243, respectively. Tonnage and Simmon...
متن کاملChlorophyll fluorescence emission spectrum inside a leaf.
Chlorophyll a fluorescence can be used as an early stress indicator. Fluorescence is also connected to photosynthesis so it can be proposed for global monitoring of vegetation status from a satellite platform. Nevertheless, the correct interpretation of fluorescence requires accurate physical models. The spectral shape of the leaf fluorescence free of any re-absorption effect plays a key role i...
