چکیده
AbstrakData keanekaragaman durian (Durio zibethinus L.) yang terbatas merupakan salah satu kendala dihadapi dalam pengelolaan dan pengembangannya di Indonesia. Keanekaragaman genetik dapat ditinjau berdasarkan ciri morfologi didukung dengan molekuler. Tujuan penelitian ini adalah untuk mengetahui kekerabatan antar aksesi dendrogram menggabungkan data daun polimorfisme Inter Simple Sequence Repeats (ISSR). Pengamatan mengacu pada deskriptor ektraksi DNA metode CTAB telah dimodifikasi. Setelah berhasil diekstraksi, diamplifikasi tujuh primer ISSR analisis polimorfisme. Konstruksi terbentuk hasil menggunakan program NTSYS. Berdasarkan 15 diamati terdapat 5 sangat membedakan antara kelompok durian. Lai (D. kutejensis) memiliki lebih panjang hingga 24 cm lebar 16 dibandingkan 28 9 cm. Hasil amplifikasi diperoleh sebanyak 35 pita 31 bersifat polimorfik persentase berkisar 66,7–100%. Persentase mencapai 100% 842, PKBT 4, 5. mempunyai koefisien kemiripan sebesar 0,56–0,91 membentuk dua tidak memisahkan aksesi-aksesi Lai. Ciri digunakan merekonstruksi menjadi 0,48–0,96. Dendrogram secara tegas Pohon Kecamatan Serpong direkonstruksi pertama kalinya.AbstractLimited on the diversity of is one obstacles encountered in its management and development Genetic can be reviewed based morphological characteristics supported by molecular characteristics. This study aimed to determine relationship between accessions a that combines leaf morphology (ISSR) polymorphism data. Observation features refered descriptors extraction using modified method. After successful extraction, was amplified with seven primers for analysis. The construction formed NTSYS program. Based observed, greatly distinguished accession group. had longer up wider leaves than length (16 cm) width (9 cm). amplification results were obtained bands out them polymorphic PCR product ranged 66.7–100%. percentage could reach primers. an interaction coefficient 0.56–0.91 two groups which did not separate feature used reconstruct into slope 0.48–0.96. explicitly divides cluster analysis durians District has been reconstructed first time.

Analysis of translocatory balance in durian (Durio zibethinus) fruit.
We estimated translocatory balance in fruit of the tropical tree Durio zibethinus Murray on the basis of a compartment model. Rates of fruit respiration, dry weight growth and translocation increased with time. Over the 8.2 weeks of fruit development, the relative distribution of translocation was 80% to dry weight growth and 20% to respiration. The ratio of respiration rate to translocation ra...

The scientific basis of the adverse, or at times lethal, effect of ingesting durian (Durio zibethinus Murray) while imbibing alcohol has not been established. Symptoms are reminiscent of the Disulfiram-Ethanol Reaction (DER) arising from the inhibition of aldehyde dehydrogenase (ALDH). Cognizant of the inhibitory effect of sulfur compounds like disulfiram on ALDH and the rich sulfur content of ...

The objective of this study was to explore the influence of pyrolysis temperature on the physicochemical properties of biochar synthesized from durian wood (Durio zibethinus) sawdust. Surface morphological features, including the porosity and BET surface area of biochars, provide appropriate dimensions for growing clusters of microorganisms with excellent water retention capacity in soil. Oxyge...
متن کاملEffect of different purification techniques on the characteristics of heteropolysaccharide-protein biopolymer from durian (Durio zibethinus) seed.
Natural biopolymers from plant sources contain many impurities (e.g., fat, protein, fiber, natural pigment and endogenous enzymes), therefore, an efficient purification process is recommended to minimize these impurities and consequently improve the functional properties of the biopolymer. The main objective of the present study was to investigate the effect of different purification techniques...
