Persimmon, kesemek, buah kaki atau manggih hutan dalam bahasa minang adalah berbagai sebutan untuk buah yang dihasilkan oleh tanaman pohon  Diospyros kaki Thunb.  Buah kesemek mengandung berbagai nutrisi penting, anti toksik dan bahkan anti kanker. Kesemek merupakan tanaman sub tropika sehingga di Indonesia kesemek hanya beradaptasi pada ketinggian ± 1400 mdpl, seperti Alahan Panjang. Petani biasanya menggunakan anakan untuk perbanyakan, namun akibatnya tanaman membutuhkan waktu yang lama untuk berbuah, lebih dari 8 tahun. Kegiatan ini bertujuan untuk mentransfer teknologi sambung pucuk menggunakan anakan (root-sucker) sebagai batang bawah (root-stock) sebagai upaya untuk mendapatkan perbanyakan kesemek secara cepat dan tanaman cepat berbuah. Mitra kegiatan ini adalah kelompok tani Harapan Baru yang berada di Batu Bagiriek Alahan Panjang Kabupaten Solok, Sumatera Barat dari bulan Oktober hingga Desember 2016. Metode kegiatan meliputi penyuluhan, demonstrasi dan pelatihan grafting. Hasil kegiatan adalah petani meningkat pengetahuannya tentang manfaat buah kesemek, teknik budidaya dan pasca panen serta mampu melakukan grafting atau penyambungan pada kesemek menggunakan root-sucker (anakan) sebagai batang bawah. Berdasarkan hasil uji statistika menggunakan analisis Likert, kegiatan pengabdian masyarakat yang dilakukan memiliki nilai indeks 92, menunjukkan bahwa kegiatan yang dilakukan bermanfaat atau berhasil mentransfer pengetahuan dan juga keterampilan kepada petani.

Penelitian bertujuan untuk memperbanyak tanaman secara vegetatif dari pemisahan tunas akar dengan perlakuan auksin guna mendukung pengembangan pembibitan tanaman kesemek. Perbanyakan tanaman dilakukan dengan tunas akar yang direndam dengan auksin (IAA, IBA, NAA, dan Root-up; masing-masing 100 ppm), serta perlakuan kontrol. Hasil penelitian menunjukkan perlakuan IAA, NAA dan Root-up 100 ppm menghasilkan tunas lebih awal dibandingkan dengan kontrol dan IBA 100 ppm. Tingkat kematian bibit tertinggi mencapai 50% terjadi pada perlakuan Root-up 100 ppm dan kontrol. Jumlah tunas terbanyak dihasilkan oleh perlakuan IAA dan IBA sebanyak 16.5 dan 17.0 tunas.

An excised twig assay was developed to evaluate cherry geno-types for their tolerance to Pseudomonas syringae pv. syringae. One-year-old wood was collected at monthly intervals from October until January of `Royal Ann', `Corum', and a number of cherry rootstock. The rootstock included; F/12–1 and Giessen (GI) and M × M selections. A 2-cm incision (“^”-shaped flap) was made on each twig. A 20-μl droplet of inoculum or water was placed onto each incision. The inoculum was prepared with one avirulent (K4) and three virulent strains (W4N54, AP2, B15) concentrations (105, 106, or 107 cfu). Inoculated twigs were placed in test tubes and incubated at 15C in high relative humidity for 3 weeks. After incubation, twigs were evaluated for gummosis production (0–3, 0 = no gummosis), incision browning (1–4, 1 = yellow pith), and callus production (0–1, 0 = no callus). The concentration of bacterial suspension had no effect on symptom development. No gummosis or browning was observed on twigs inoculated with water or the avirulent strain. Based on the gummosis and browning ratings, rootstock M × M 2, M × M 39, M × M 60, GI 148-1, GI 154-2, and GI 154-4 were found to be resistant to these three strains of P. syringae in this assay. Root-stock F 12-1, GI 169–15, GI 172–9, and GI 173-9 were found to be tolerant.

Background: phenolic compounds are bioactive chemical species derived from fruits and vegetables, with a plethora of healthy properties. In recent years, there has been a growing interest in persimmon (Diospyros kaki L.f.) due to the presence of many different classes of phenolic compounds. However, the analysis of individual phenolic compounds is difficult due to matrix interferences. Methods: the aim of this research was the evaluation of individual phenolic compounds and antioxidant capacity of the pulp of two varieties of persimmon (Rojo Brillante and Triumph) by an improved extraction procedure together with a UPLC-Q-TOF-MS platform. Results: the phenolic compounds composition of persimmon was characterized by the presence of hydroxybenzoic and hydroxycinnamic acids, hydroxybenzaldehydes, dihydrochalcones, tyrosols, flavanols, flavanones, and flavonols. A total of 31 compounds were identified and 17 compounds were quantified. Gallic acid was the predominant phenolic compounds found in the Rojo Brillante variety (0.953 mg/100 g) whereas the concentration of p-hydroxybenzoic acid was higher in the Triumph option (0.119 mg/100 g). Conclusions: the results showed that the Rojo Brillante variety had higher quantities of phenolic compounds than the Triumph example. These data could be used as reference in future phenolic compound databases when individual health effects of phenolic compounds become available.

Natural Drying

Persimmon (Diospyros kaki L.f.) crop has markedly increased in Spain, and “Rojo Brillante” persimmon is the main cultivated variety. This astringent cultivar requires de-astringency treatment before commercialization, which may involve an extra cost. Its short commercial season implies handling large volumes of fruits with consequent postharvest losses. Therefore, the development of derived added-value products is of much interest. In this study, astringent and non-astringent “Rojo Brillante” persimmons were dehydrated by following a natural drying method used in Asia. The drying kinetics and physico-chemical properties were analyzed for 81 days. The results indicated subsequent reductions in weight, water content, and water activity throughout the drying process, and the equatorial diameter decreased. All the employed thin-layer mathematical models were suitable for representing the drying characteristics of both products with similar behavior. The effective water diffusivity values were 5.07 × 10−11 m2 s−1 and 6.07 × 10−11 m2 s−1 for astringent and non-astringent persimmon samples, respectively. The drying treatment significantly decreased the soluble tannins content, and the astringent samples obtained similar values to those obtained for the non-astringent samples in 20 days. The external and internal flesh of the astringent fruit remained orange through the drying period, while brown coloration in the non-astringent fruit was observed after 57 drying days. Therefore, prior de-astringency treatment would not be necessary.
