Salinity and alkalinity are two of the main causes for productivity losses in agriculture. Quinoa represents a better alternative for global food products such as rice and wheat flour due to its high nutritional value and abiotic stress tolerance. Three cultivars of quinoa seeds (Titicaca, Puno and Vikinga) originating from Denmark were used in the experiments. The seeds were germinated under the action of three different salts (NaCl, Na2SO4, Na2CO3) at 0–300 mM for five days and the germination rate was calculated. Biometric measurements (radicle and hypocotyls lengths) andbiochemical determinations (proline) were performed in order to quantify the tolerance and the effects of salt and alkali stresses on the three quinoa cultivars. The germination rates showed that all cultivars were affected by the presence of salts, especially at 300 mM. The most sensitive cultivar to salts was Titicaca cultivar which evinced the lowest germination rate, regardless of the salt and the concentration used. On the other hand, Puno and Vikinga cultivars showed the best tolerance to the saline and alkaline stresses. Among the salts used, Na2CO3 had the most detrimental effects on the germination of quinoa seeds inhibiting the germination by ~50% starting with 50 mM. More affected was the growth of hypocotyls in the presence of this salt, being completely inhibited for the seeds of the Puno and Titicaca cultivars. Vikinga cultivar was the only one able to grow hypocotyls at 50 and 100 mM Na2CO3. Also, this cultivar had a high adaptability to NaCl stress when significant differences were observed for the germination rates at 200 and 300 mM as compared to 0 mM NaCl, due to the proline production whose content was significantly greater than that of the untreated seeds. In conclusion, the tolerance of the three quinoa cultivars to saline and alkali stress varied with the salt type, salt concentration and tested cultivar, with the Vikinga and Puno cultivars showing the best potential for growing under saline conditions.

Suaeda moquinii (Torrey) Greene (desert blite), a succulent shrub in the family Chenopodiaceae, is widely distributed in salt marshes of the western United States. Suaeda moquinii produces dimorphic seeds (soft brown and hard black). Both types of seeds were collected from a salt marsh in Faust, Utah. Experiments were conducted to determine the seed germination responses of the black and brown seeds to salinity and temperature. Brown seeds were found to be one of the most salt tolerant at the germination stage when compared to other halophytes. Brown seeds germinated (30%) at 1000 mM NaCl, but only a few black seeds germinated (8%) at 600 mM NaCl. Seed germination occurred in most saline treatments at the lowest thermoperiod (5–15˚C) tested. In some salinity treatments (600, 800, 1000 mM), further increases in temperature resulted in progressively decreased seed germination. Brown seeds germinated better and had a higher germination rate (germination velocity) than black seeds at all thermoperiods. The highest rate of germination of black seeds occurred at the lowest thermoperiod (5–15˚C). Recovery of germination for black seeds when transferred to distilled water after being in various salinity treatments for 20 days was nearly complete (82–100%) at the lowest thermoperiod (5–15˚C) but decreased with increase in the temperature. Brown seeds recovered substantially (59–97%) from salinity at all thermoperiods. Regression analyses indicated significant differences between the germination recovery of the black and brown seeds.

ABSTRACTIn vitro method to fasten availability high quality soybean seedsSoybean is an important crop as a source of food and its demand has increased every year. Several new varieties of soybean have been generated, but the number is still limited. Furthermore, the infestation of pests and infection of diseases have also limited the new soybean varieties production as it increase the risk of growth failure. Therefore, methods to fasten the availability of high quality of soybean seeds need to be developed. One of which can be done through in vitro culture method. The objective of this study was to obtain the best type and the best concentration of cytokinin for the growth of soybean explants in vitro. The experiment was conducted in Seed Technology and Tissue Technology Laboratory, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was Completely Randomized Design with 13 treatments and four replications. The basic media used were Murashige and Skoog (MS) + Vitamin B5 with addition of BAP (1.0 mg/l, 1.5 mg/l, and 2.0 mg/l), Kinetin (0.5 mg/l, 1.0 mg/l, and 1.5 mg/l), TDZ (0.01 mg/l, 0.1 mg/l, and 1.0 mg/l), and coconut water (10%, 15%, and 20%). The result showed that cytokinin types and concentrations gave different effect to soybean explant growth. The best treatment was demonstrated by BAP at the concentration of 1.5 mg/l as shown by the highest percentage of leaves and the number of shoots. However, it did not affect the percentage of buds produced by explant and the percentage of callus produced by explant.Keyword : BAP, Kinetin, TDZ, Coconut water, Soybean.AbstrakKedelai merupakan komoditas yang memegang peranan penting.

Seeds from mature seed pods of Cypripedium calceolus var. parviflorum were germinated on 1/4 MSMO (Sigma) + 100ml/l coconut water + 1% sucrose +/- 8g/l agar (pH 6.0), and with or without prechilling at 5C for 8 weeks. Protocorm with apex (stage 3) was use as an index of germination. Seeds sown on agar medium withou chilling treatment resulted in a 40% germination rate in 120 days but the germination was very uneven. Seeds germinated on agar medium with prechilling developed more synchronously with 92% germination in 60 days (ie. about 120 days after sowing). Suspension culture of seeds without prechilling resulted in 85% germination after 90 days. The synchronization of seed germination in suspension culture was intermediate between that on agar with and without prechilling. Protocorms germinated in suspension culture appeared morphologically identical to those germinated on agar medium. All stage 3 protocorms developed further on the same agar medium in darkness. Both agar and suspension culture in media containing coconut water provided reliable seed germination methods for this orchid species.
