Albizia zygia produces valuable timber which has received some level of prominence in the international market. However, the seeds are dormant, and the tree species remain undomesticated. This study was conducted to evaluate the effect of seed size and presowing on the germination of Albizia zygia in a nursery. Seeds were grouped into four categories in regard to their length, small (≤0.5 cm), medium (> 0.5 < 0.8 cm), large (≥0.8 cm), and mixture of small, medium, and large seeds. The seeds were subjected to five main seed pretreatment methods, namely, soaking in sulphuric acid (H2SO4) for 2 minutes, mechanical scarification, soaking in hot water for 5 minutes, soaking in cold water for 24 hours, and control where seeds were sown without any treatment. The results indicate that combination of mechanical scarification and large seeds produced the highest (100%) germination. Hot water treatment was effective in large seeds producing 69.0% germination. The increased germination for mechanically scarified seeds suggests that seed dormancy in Albizia zygia is mainly due to its hard seed coat. Therefore, it is recommended to farmers to adopt use of mechanical scarification and large seeds, since it is safe and effective.

Albizia lebbeck is a multipurpose tree species prioritised for conservation in Malawi. The different plant parts are used in traditional medicine to treat different diseases. However, the seeds are dormant, and the tree species remain undomesticated. A study was conducted to evaluate the effect of seed size and presowing on the germination of Albizia lebbeck in a nursery. Seeds were grouped into four categories in regard to their length, small (≤0.5 cm), medium ( cm), large (≥0.8 cm), and mixture of small, medium, and large seeds. The seeds were subjected to five main seed pretreatment methods, namely, soaking in sulphuric acid for 2 minutes, nicking, soaking in hot water for 5 minutes, soaking in cold water for 24 hours, and control where seeds were sown without any treatment. The results indicate that combination of nicking and large seeds produced the highest (100%) germination. Hot water treatment was effective in large seeds producing 67.5% germination. The increased germination for mechanically scarified seeds through nicking suggests that seed dormancy in Albizia lebbeck is mainly due to its hard seed coat. Therefore, it is recommended to farmers to adopt use of nicking and large seeds, since it is safe and effective.

The seeds of Albizia lebbeck have been observed to exhibit physical dormancy due to presence of hard seed-coat. To overcome this problem, the seeds were subjected to seven pre-sowing treatments viz., T1-immersion of seeds in cold water for 12 h; T2-immersion of seeds in cold water for 24 h; T3-immersion of seeds in hot water (100 °C) and subsequent cooling at room temperature for 12 h; T4-immersion of seeds in hot water (100 °C) and subsequent cooling at room temperature for 24 h; T5-immersion of seeds in cold water for 12 h followed by immersion in hot water (100 °C) and allowed to cool for 1 h; T6-immersion of seeds in cold water for 24 h followed by immersion in hot water (100 °C) and allowed to cool for 1 h. Untreated seeds served as control (T0). Treatment T3 gave highest germination (96%) which was comparable with T5 (95 %), T4 (94 %) and T6 (93%). Nine growing media viz., T1: soil,  T2: soil+sand (2:1), T3: soil+perlite (2:1), T4: soil+Farm Yard Manure (FYM) (2:1), T5: soil+vermicompost (2:1), T6: soil+sand+FYM (1:1:1), T7: soil+sand+vermicompost (1:1:1), T8: soil+perlite+FYM (1:1:1) and T9: soil+perlite+ vermicompost (1:1:1) were, also, studied for their effect on seedling growth of A. lebbeck. Among these media, maximum values of shoot length (23.82 cm), root length (21.14 cm), collar diameter (3.59 mm) and seedling quality index (0.350) were observed in T7.

The study was conducted at the Laboratory of the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, during March to August, 2008 to examine the effect of hot water treatment at different temperatures with varying immersion periods on the viability of Sesbania rostrata seeds. Effect of dipping seeds in hot water at temperature of 78, 79, 80 and 810C for 24, 25, 26, 27 and 28 min were evaluated for this purpose. The lowest seed viability and seed germination (0.5%) was obtained at 81 0C for 28 min immersion period. The lowest hard seed (3.0%) and minimum (0.63%) pathogenic infection was found at same temperature and immersion period. Germination and tetrazolium tests were used throughout the experiment for estimating seed viability. Extreme hot water treatment deteriorated the viability of Sesbania rostrata seeds.

Ditylenchus Destructor

The Effectiveness of Hot Water Treatment Against Nematode  Ditylenchus destructor on Garlic BulbsThe high importation of garlic increases the risk of entry and spread of Ditylenchus to Indonesia. The hot water treatment (HWT) has the potential to be developed as an effective and safe method for elimination Ditylenchus in garlic. The aim of the current research was to examine effectiveness of HWT application on imported garlic to eliminated Ditylenchus. The research consisted of garlic sampling, nematode identification and determination of population abundance, and HWT. Samples were taken from traditional markets. The range of HWT temperature tested was 41, 43, 45, 47, 49, 51, 53, and 55 °C for 20 minutes and control. Optimization of treatment time was carried out at 49–51 °C for 5, 10, 15, 20, 25, 30 minutes and control. The results showed that based on morphological characters the parasitic nematodes that infect imported garlic from China were D. destructor. Nematode populations are varied in the sample, the highest number was 508 nematodes per 50 g of garlic. Hot water temperature at 41–51 °C did not affect the quality of garlic, and the temperature of 49–55 °C caused 100% nematode mortality. Hot water at 49 °C for 20–30 minutes or 51 °C for 20–25 minutes effectively eliminated Ditylenchus in garlic without affecting the garlic quality. The research confirmed the presence of D. destructor in imported garlic imported from China, so it is recommended to tighten inspection at a port of entry and monitoring its potential spread in Indonesia.

Treated Seed

The majority of the seed sprout–related outbreaks have been associated with Escherichia coli O157:H7 and Salmonella. Therefore, an effective method for inactivating these organisms on the seeds before sprouting is needed. The current pasteurization method for mung beans in Japan (hot water treatment at 85°C for 10 s) was more effective for disinfecting inoculated E. coli O157:H7, Salmonella, and nonpathogenic E. coli on mung bean seeds than was the calcium hypochlorite treatment (20,000 ppm for 20 min) recommended by the U.S. Food and Drug Administration. Hot water treatment at 85°C for 40 s followed by dipping in cold water for 30 s and soaking in chlorine water (2,000 ppm) for 2 h reduced the pathogens to undetectable levels, and no viable pathogens were found in a 25-g enrichment culture and during the sprouting process. Practical tests using a working pasteurization machine with nonpathogenic E. coli as a surrogate produced similar results. The harvest yield of the treated seed was within the acceptable range. These treatments could be a viable alternative to the presently recommended 20,000-ppm chlorine treatment for mung bean seeds.

Postharvest Treatments

Mango (Mangifera indica L.) is a popular fruit in the international market due to its excellent flavor, attractive fragrance, taste and nutritional properties. However, it is highly perishable since it ripens easily after harvest and it is susceptible to postharvest diseases causing severe losses during storage and transport. The paper reviews the literature on the most important postharvest treatments to alleviate this problem which include the use of fungicides, hot water treatment, vapor heat treatment, controlled atmosphere, irradiation, wax coatings and biological control. The use of fungicides, hot water treatment, irradiation, and wax coatings appear to be the most widely used postharvest treatments.
