Abstract. Ku-or Y, Leksungnoen N, Ngernsaengsaruay C, Andriyas T. 2020. Seed longevity of Buchanania siamensis Miq. in reclaiming salt-affected areas in Thailand. Biodiversitas 21: 743-747. Inland salinity is a grave threat to soil fertility as it causes loss of arable land. Salt-tolerant species, such as Buchanania siamensis Miq., can be used for the reclamation of land affected by salinity. We investigated the appropriate conditions to store the seeds of B. siamensis and the storage duration after which the seeds can still germinate. Storage methods included cooling at 4°C and storing at room temperature (between 25-30°C). Seeds kept at 4°C had low germination (6.75% ± 1.71), with longevity of only up to a week, compared to seeds stored at room temperature, which had germination of 94% ± 4.00 and could be stored for more than 200 days. Seed-longevity test was conducted at 14 levels (the number of storage days). Germination was reduced by 50% after 3.5 months, indicating that the seed could only be stored for the short term. The seeds were classified as having an intermediate behavior in which the germination increased exponentially with increasing seed moisture content. We recommend that seeds be stored at a temperature between 25 and 30°C, with sowing done within 3.5 months to obtain germination at or above 50%.

Аim. To determine the optimum moisture content and comparative longevity of seeds of wheat species accessions for long-term storage according to the results of the “accelerated seed aging” experiment. Results and Discussion. There was estimated seed longevity of the representatives of wheat species Triticum aestivum L., T. spelta L., T. durum Desf., T. dicoccum (Schrank) Schuebl., T. monococcum L., T. sinskajae A. Filat. et Kurk. of three reproduction years – 2014, 2016 and 2017, at three moisture levels – 5 %, 6 % and 7 % in the experiment with accelerated aging. Germination energy and germination rate depended on the year conditions, seed moisture, the interactions year – genotype, year – seed moisture and all three factors: year conditions, seed moisture, genotype (influence power from 16.1 to 20.1). Accelerated aging caused decrease in seed germination energy and germination rate in almost all samples at all three moisture levels. Under the accelerated aging, with an increase in seed moisture content from 5 % to 7 %, on average by the accessions, the seed germination energy (from 83 % to 63 %) and germination rate (from 90 % to 68 %) decreased on samples. At all three moisture levels, relatively high germination energy and germination rate after accelerated aging had T.monococcum (86-95 % and 88-97 %) and Polba 3 (74-96 % and 85-98 %). A low germination energy (66-69 % и 68-77 %) and germination rate showed T.sinskajae UA0300224 (66-69 %) and T.durum Spadschyna (56-75 % и 61-92 %). At all three seed moisture levels, the high plasticity of germination energy had T.sinskajae UA0300224 and T.durum Spadschina, germination rate – T.sinskajae. With all three seed moisture levels, T.sinskajae UA0300224 and T.aestivum Harkivska 26 were characterized by stable germination rate. Conclusions. The highest seed longevity of the studied accessions is provided by moisture of 5%, less but close longevity – the moisture of 6%. The least longevity in three test options had seeds with 7 % moisture content. Among studied accessions of wheat species most longevous seeds had T.monococcum UA0300439 and Polba 3. The seeds of T.sinskajae UA0300224 and T.astivum PI619379 were less longevous.

Aim. Analysis of soybean (Glycine max (L.) Merr.) germplasm seed longevity with different biochemical composition for further storage optimization in active collections and during long-term storage. Methods. The content of protein, oil, fatty acid composition (palmitic, palmitic-oleic, stearic, oleic, linoleic, linolenic, eicosenic, behenic) in experimental soybean seed samples was analyzed. The process of accelerated storage aging, storage at –20°C were carried out at original seed moisture content and after additional drying. Laboratory and field indexes of seed germinability, mophophysiological state of seedlings, elements of crop structure were evaluated. Results. The longevity of soybean seed germplasm with different biochemical composition, different degree of drying was determined. The statistical relationship between fatty acid content and germination of soybean seeds in experimental and control variants was established. Conclusions. Drying to 4% seed moisture content extends the longevity of soybean seeds with different biochemical composition. Extra drying should be applied in special modes even for seeds with 7% moisture content. Keywords: germplasm, soybean, storage, longevity, moisture content.

In this paper, we considered the effects of different drying regimes on the subsequent longevity of Bambara groundnut seeds. Freshly harvested Bambara groundnut seeds from 27 genebank accessions were divided into five samples. One sample (control) was immediately dried at 17°C/15% RH and the other samples were dried at 45°C/35% RH for up to eight days, before transfer to 17°C/15% RH. After drying, seed moisture content was raised to 10.9% before packing the seeds in aluminium foil packets and placing at 45°C. Samples were removed at regular intervals for germination tests to compare seed longevity. Initial drying at the higher temperature resulted in a faster reduction in seed moisture content. The effect of the different drying regimes on subsequent longevity was not significant for most accessions. Nonetheless, the seed longevity of smaller-seeded accessions was perhaps enhanced by initial drying at a higher temperature; in contrast, initial drying at 17°C appeared to be the best drying treatment for larger-seeded accessions. Overall, the results suggest that initial drying at a higher temperature was beneficial for reducing processing time and for some accessions would be beneficial for seed longevity, but further work is required to understand for which seed lots.

Malva Parviflora

Seed development was examined in Malva parviflora. The first flower opened 51 days after germination; flowers were tagged on the day that they opened and monitored for 33 days. Seeds were collected at 12 stages during this period and used to determine moisture content, germination of fresh seeds and desiccation tolerance (seeds dried to 10% moisture content followed by germination testing). Seed moisture content decreased as seeds developed, whereas fresh (max. 296 mg) and dry weight (max. 212 mg) increased to peak at 12–15 and ~21 days after flowering (DAF), respectively. Therefore, physiological maturity occurred at 21 DAF, when seed moisture content was 16–21%. Seeds were capable of germinating early in development, reaching a maximum of 63% at 9 DAF, but germination declined as development continued, presumably due to the imposition of physiological dormancy. Physical dormancy developed at or after physiological maturity, once seed moisture content declined below 20%. Seeds were able to tolerate desiccation from 18 DAF; desiccation hastened development of physical dormancy and improved germination. These results provide important information regarding M. parviflora seed development, which will ultimately improve weed control techniques aimed at preventing seed set and further additions to the seed bank.
