Dual Treatment

Fresh date palm fruits (cv. Barhi) have received much attention due to their sweet taste and popularity in marketing. There is a critical need to prolong their storability, as well as maintain their quality during the postharvest and marketing periods. In this study, the effects of spraying date palm trees with melatonin (Mt) and/or methyl jasmonate (Mj) at 10, 20, and 50 ppm, on their growth and yield were investigated. In addition, impacts on quality and storability of the fruits were also studied. In general, application of Mt was mostly more effective than that of Mj, even at 50 ppm, with regard to all evaluated parameters. However, the dual treatment at 50 ppm recorded the highest relative chlorophyll and nutrient content in date palm leaves, as well as the yield and its components. Regarding the date palm fruits stored at 4 °C for 28 days, this dual treatment recorded the lowest weight loss and fruit decay values (0.14 and 2%, respectively), the highest firmness (6 g·cm−2), total soluble solids content (36 °Brix), total sugar content (32.5 g/100 g fresh weight), and the lowest total acidity (0.16 g citric acid/100 mL juice). Moreover, the highest total phenolic content and activity of peroxidase and polyphenol oxidase enzymes in the stored fruits were also recorded for the dual treatment. In contrast to the untreated fruits, scanning electron microscopy observations showed that the sprayed fruits had a very good microstructure, showing intact and thick exocarp tissue with a dense layer of epicuticular wax. The mesocarp tissue showed a normal and clear cellular framework with well organized and arranged cells, after 28 days storage at 4 °C. Based on these results, we can conclude that application of the dual treatment (Mt + Mj) at 50 ppm is a promising way to prolong the storability of date palm fruits and maintain their quality during storage periods.

<p>Pertumbuhan dan daya hasil dari berbagai klom nilam dievatuasi di KP. Cimanggu (Bogor) dari tahun 1999 - 2000. Dua puluh dua klon nilam yang berasal dai kultur kalus yang diradiasi dengan sinar gamma, 1 klon kontrol (asal kultur mata tunas) serta 3 klon pembanding (Klon TT, Sdk dan Crt) ditanam dengan jarak tanam 100 cm x 50 cm. Percobaan dirancang secara acak kelompok dengan 3 ulangan. Luas petak adalah 10 m2 yang memuat 20 tanaman. Parameter yang digunakan adalah sifat- sifat morfologi, yang meliputi tinggi tanaman, diameter batang, jumlah dan panjang cabang, jumlah daun per cabang, panjang dan lebar daun serta komponen hasil, yang meliputi berat tanaman, berat tcrsuling (segar dan kering) dan kadar minyak. Hasil penelitian menunjukkan bahwa berdasarkan sifat-sifat morfologi dan komponen hasil terdapat 4 klon yang mcnonjol. yaitu 3 klon hasil kultur jaingan (klon lb, 2b, dan 75) dengan hasil tema kering masing-masing 0.222; 0.222; dan 0. 216 kg/tanaman dan kadar minyak masing-masing 4.28; 4.00; dan 4.54%, serta satu klon konvensional (Ct) dengan hasil tema keing 0.469 dan kadar minyak 4.84%.</p><p>Kata kunci: Pogostemon cablin, nilam, klon, kultur jaringan</p><p> </p><p><strong>ABSTRACT </strong></p><p><strong>Evaluation on the growth and yield potency of different clones ofpatchoulifrom tissue culture</strong></p><p>The growth and yield potency of different patchouli developed from tissue culture were studied at the Cimanggu Experimental Garden from 1999 to 2000. The materials were twenty-two clones of patchouli raised rom the gamma irradiated calli, 1 control clone (raised rom tissue culture propagated plant from which the irradiated calli were derived) and 3 conventionally propagated clones (Crt, TT and Sdk). The planting mateials were planted in a plant spacing of 100 cm x 50 cm. The experiment was designed as a randomaized block in 3 replicates. Plot size was 10 m2, accommodated 20 plants. Parameters used for evaluating the clones were morphological characters and yield components. The morphological characters included plant height, stem diameter number of branches, number of leaves per branch and size of leaves, while the yield component included weight of whole plant, distilled herbs (fresh and dry herbs) and oil content. Based on die morphological characteristics and yield components, 4 clones showed their superioity. The four clones were lb, 2b, and 75 (raised from tissue culture) with a herb yield of 0.222; 0.222 and 0216 kg/plant and an oil content of 4.28, 4.00 and 4.84% respectively, and Ct ( from convetional clone) with a herb yield of 0.469 kg/plant and an oil content of 4.84%.</p><p>Key words : Pogostemon cablin, nilam, clones, tissue culture</p>
