SUMMARYExperiments, conducted over 3 years, investigated the effect of all combinations of two storage periods at low temperature (0 or 2 °C) and two storage periods at 10 °C on the sprout growth, numbers of stems per tuber, foliage development and subsequent tuber yield of the two maincrop varieties Maris Piper and Désirée.Although the number of day-degrees accumulated during sprouting was the same for all treatment combinations, there were large effects of treatments on the number of sproutlets per tuber and the total sprout length per tuber. However, there was no effect on the number of stems per tuber, foliage development or saleable ware yield inany year.

Sari. Kentang (Solanum tuberosum L.) adalah salah satu komoditas yang mendapat prioritas pengembangan, karena produk tanaman ini dipakai sebagai sumber karbohidrat serta memiliki potensi dalam diversifikasi pangan. Salah satu permasalahan dalam produksi kentang adalah terbatasnya persediaan benih kentang, karena adanya fase dormansi. Percobaan ini bertujuan untuk mengetahui interaksi antara suhu penyimpanan dan konsentrasi sitokinin terhadap pematahan dormansi benih kentang. Rancangan percobaan yang digunakan adalah Rancangan Petak Terbagi (Split Plot Design) dengan tiga ulangan.  Petak utama adalah suhu penyimpanan dengan tiga taraf, yaitu: suhu rendah ±10oC , suhu ruang  ±25oC  dan suhu tinggi ±30oC. Anak petak adalah empat taraf konsentrasi sitokinin, yaitu: 0 mgL-1, 50 mgL-1, 100 mgL-1, dan 150 mgL-1. Hasil percobaan menunjukkan terdapat pengaruh interaksi antara suhu penyimpanan dengan konsentrasi sitokinin dalam mempercepat pematahan dormansi benih kentang. Penyimpanan benih kentang pada suhu ruang disertai pemberian konsentrasi sitokinin 50 mgL-1 dapat mempercepat pematahan dormansi benih kentang G2. Perlakuan suhu rendah menghasilkan tunas yang lebih panjang tapi bobotnya tidak berbeda dengan yang diberi perlakuan suhu ruang dan suhu tinggi, sedangkan pengaruh perlakuan sitokinin tidak berbeda terhadap panjang tunas, persentase tumbuh tunas per ubi, dan bobot segar tunas.Kata Kunci : Benih Kentang, Suhu Penyimpanan, Sitokinin, DormansiAbstract. Potato (Solanum tuberosum L.) is one of the important agriculture commodities, because it contains carbohydrates and can use for food diversification in Indonesia. One of the problems in potato production is the limited of seed potatoes, because of potato seed dormancy. This experiment analyzed the interaction between storage temperature and concentration of cytokinin on dormancy breaking of potato seed. The experimental design used Split Plot Design with three replications. The main plot was the temperature of storage, that consisted of three levels: low temperature ± 10°C, room temperature  ± 25°C and high temperature  ± 30oC. Subplot consisted of four levels of cytokinin concentration: 0 mgL-1, 50 mgL-1, 100 mgL-1 and 150 mgL-1. The results of the experiment showed that there was an interaction effect between storage temperature and cytokinin concentration on accelerating the breakdown of potato seed dormancy. Storage of seed potatoes at room temperature with application of 50 mgL-1 cytokinin accelerated the breakdown of G2 potato seed dormancy.  Low temperature treatment resulted longer shoot but the weight was not different than other temperature treatments, whereas cytokinin treatment did not differ in shoot length, percentage of bud growth per seed, and fresh weight of shoots.Keyword: Potato Seed, Storage Temperature, Cytokinin, Dormancy

SummaryStorage experiments were performed at 4°, 25° and 37° C with platelet-rich plasma under sterile conditions. In some experiments also the effect of storing platelets at 4° C in whole blood was investigated.Before, during and after three days of storage, the platelets were tested at 37° C for their serotonin uptake and response to hypotonic shock. In addition some glycolytic intermediates were determined.A fair correlation was noticed between the serotonin uptake and hypotonic shock experiments. Both parameters were best maintained at 25° C. Also platelet counting, performed after the storage period, indicated 25° C as the best storage temperature. Determination of glycolytic intermediates did not justify any conclusion regarding the optimal storage temperature. Of the various anticoagulants studied, ACD and heparin gave the best results as to the serotonin uptake and hypotonic shock response, either with fresh or stored platelets. The use of EDTA resulted in the lowest activity, especially after storage.The results of these storage experiments in vitro, correspond well with those in vivo reported in the literature.

ABSTRAKPenelitian ini dilakukan untuk mengetahui motilitas dan viabilitas spermatozoa ayam kampung pada suhu 5oC menggunakan pengencer dan lama simpan yang berbeda. Metode yang digunakan dalam penelitian ini adalah penelitian laboratorium menggunakan Rancangan Acak Lengkap (RAL) Faktorial dengan pengencer ringer lactat solution, air kelapa dan tanpa pengencer serta lama simpan 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, masing-masing diulang 10 kali. Variabel yang diamati yaitu motilitas dan viabilitas spermatozoa. Analisa data yang digunakan adalah analisis varian. Hasil analisis data menunjukkan bahwa motilitas dan viabilitas spermatozoa menggunakan pengencer ringer lactat solution lebih tinggi (P<0,01) serta dapat bertahan sampai lama simpan 24 jam dibandingkan air kelapa dan tanpa pengencer. Adapun nilai motilitas ringer lactat solution, air kelapa dan tanpa pengencer pada lama simpan 24 jam masing-masing sebesar 43,5±17,17%; 8±4,83%; 6,5±2,4%, sedangkan nilai viabilitasnya sebesar 83,2±7,25%; 64,6±3,20%; dan 63,1±2,33%. Kesimpulan dari hasil penelitian ini adalah ringer lactat solution lebih baik dibandingkan air kelapa dan tanpa pengencer dalam mempertahankan kualitas semen ayam kampung pada suhu simpan 5oC sampai lama simpan 24 jam.Kata Kunci : air kelapa, ayam kampung, motilitas, spermatozoa, viabilitas  ABSTRACTThis study was conducted to determine the motility and viability of spermatozoa of Native chickens at 5oC using different diluents and time storage. The method used in this study was laboratory research using Factorial Completely Randomized Design with ringer lactate solution, coconut water and without diluent at 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 hours of time storage each repeated 10 times.
