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

Chipping Quality

Acceptable chip quality based on chip color was obtained in five potato cultivars freshly harvested in August, September and October. Placing the tubers in 5 °C storage severely impaired chip quality. Reconditioning the tubers at 21 °C for 2 weeks improved chip quality in the cultivar Kennebec harvested in October and in two experimental cultivars, F5208 and F5889 harvested in September and October. Tubers of the cultivars Warba and Irish Cobbler from all harvests failed to become reconditioned satisfactorily. Preconditioning tubers at 21 °C before storing them at 5 °C and then reconditioning at 21 °C improved chip color in all cultivars. The color improved to an acceptable level in tubers of Kennebec harvested in October and of the experimental cultivars harvested in September and October. In these also, preconditioning produced good chip color when tubers were chipped directly from 5 °C storage. Tubers from all harvests of the experimental cultivar F5889, including those harvested when immature in August, chipped well from storage at 5 °C after 5 weeks of preconditioning at 21 °C.
