Swertia chirayita is a highly endangered and very well known medicinal plant enlisted in the IUCN list of endangered plants in the world. The plant is currently having a very low population in eastern Himalayan region due to its very low germinability in its own natural habitat. The plant population was found to have a range of diversity in morphological observations and some of the morphovariants were found to be very low among the variant populations which created a concern due to its diminishing range of genetic base in this region. A basic group of 5 morphovariants and 24 sub variants were identified and separately maintained. It is a pluriannual plant and reproductive or flowering stage was observed after completion of two years of vegetative stage from the time of seed germination. A range of morphovariant diversity was observed in the populations of Neora Valley and Lava region of eastern Himalaya in our investigation. Diversity was critically observed in some of the parameters of different morphovariants in the population. Conservation practices were generally done by not making groups or sub groups of this endangered plant while we proposed the way of conservation by making groups for proper conservation of this vulnerable plant.

“…Seed deterioration starts immediately after harvest and therefore, post-harvest handling of rice seed plays a key role in the maintenance of seed quality (Vange et al, 2016). It is important to preserve the genetic integrity of seeds during storage to retain high seed quality (Pradhan & Badola, 2012). Factors that affect the quality of seed during storage include drying temperature, moisture content, storage temperature, oxygen supply, pest and diseases, packaging material and duration of storage (Muangkaeo et al, 2005;Chattah et al, 2012;Jyoti & Malik, 2013).…”

Storage temperature and moisture content are the most crucial (Pradhan & Badola, 2012). The optimum moisture content for storing rice seed is between 12-14% (Whitehouse et al, 2015).…”

Inappropriate seed packaging and seed dormancy affects seed quality and consequently leads to reduced crop stand, low seedling vigour and reduced yields. The objective of the study was to determine the effect of seed packaging material and seed treatment on viability and dormancy in rice seeds. Effect of packaging material was evaluated by storing freshly harvested seeds of Basmati 370 and BW 196 varieties in polythene, khaki, cheese cloth, polypropylene (Pp) sack and gunny bag sat room temperature and at 6 o C for six months. Effect of seed treatment on dormancy was determined by pre-treatment of seeds with nitric acid at 0.1 M, 0.2 M, 0.5 M, 1 M and 2 M, gibberellic acid (GA 3 ) at 1000 ppm, 2000 ppm and 5000 ppm, and hydrogen peroxide at 0.5 M, 1 M, 2 M, 3 M, 5 M and dry heat at 50 o C for 48 hours. The seeds were subjected to germination test on moist paper and data on percentage germination, seedling length and seedling dry weight were taken. Packaging material had a significant (P ≤ 0.05) effect on germination and vigour. At room temperature, seed stored in polythene bag had the highest germination 88.2% and 57.8% for BW 196 and Basmati 370, respectively. Basmati 370 in khaki bag stored in the cold room had the highest germination 48.3%, while BW 196 stored in polythene had the highest (86.0%). Pre-treatment of seeds reduced dormancy, with variety BW 196 showing the highest germination of up to 67%, while variety Basmati 370 had the lowest germination of up to 40%. Gibberellic acid (GA 3 ) at 5000 ppm was the most effective in breaking seed dormancy resulting in up to 95.7% germination. The results of the study indicated that packaging rice seed in polythene bags for periods not exceeding six months and pre-treatment with GA 3 maintains high seed viability and breaks dormancy, respectively, thus ensuring rapid and uniform germination of vigorous seedlings. This would reduce the period farmers have to wait after harvest before they can plant newly harvested rice seeds.

“…Hal ini memberi indikasi adanya keragaman daya simpan yang cukup tinggi antar populasi jabon putih. Keragaman daya simpan benih dari beberapa populasi juga terjadi pada Swertia chirayita (Pradhan, & Badola, 2012). Dari delapan populasi yang diuji, benih dari Pomalaa memiliki mutu fisiologis (viabilitas, vigor, dan daya simpan) yang tinggi dengan parameter-parameter perkecamabah benih tertinggi pada benih sebelum dan setelah disimpan, yang diikuti oleh benih dari Batu Hijau.…”

Jabon putih [Neolamarckia cadamba (Roxb.) Bosser] has been cultivated in large scale. However it is constrained by the availability of high quality seeds and seed storability information. This study aimed to identify seed storability of jabon putih based on populations and seed morpho-physiological characteristics. Seeds were collected from eight populations, located in eight provinces. Population was a single factor in a completely randomized design for testing the germination characteristics (germination capacity, germination uniformity, germination speed, mean germination time and germination value) before and after storage. Geo-climate and soil macro elements were used as parameters to examine the correlation between environmental factors and seed characteristics before and after storage. Population was significantly correlated with germination characteristics, before and after storage for 54 months. The results indicated that seeds from Pomalaa population had the best germination characteristics, while those from Ogan Kemiring Ilir had the worst germination characteristics. Based on moisture content and storability, jabon putih seed could be categorized as orthodox that can be stored in long time at low temperatures with low moisture content. Geo-climate and soil macro element were not significantly correlated with germination. This result indicated that genetic factor had high contribution to seed storability of jabon putih.Key word : Genetic factor, morpho-physiological, ortodox seed, storage ABSTRAK Jabon putih [Neolamarckia cadamba (Roxb.) Bosser] telah banyak dibudidayakan dalam skala luas, namun terkendala dengan ketersediaan benih bermutu dan belum adanya informasi daya simpan benih. Penelitian ini bertujuan untuk mengidentifikasi karakteristik daya simpan benih jabon putih berdasarkan populasi dan karakteristik morfo-fisiologi benih. Benih dikumpulkan dari delapan populasi yang terletak di delapan provinsi. Populasi menjadi faktor tunggal dalam rancangan acak lengkap untuk menguji karakteristik perkecambahan (daya berkecambah, keserempakan tumbuh, kecepatan berkecambah, rata-rata waktu berkecambah dan nilai perkecambahan) sebelum dan setelah penyimpanan. Geo-klimat dan unsur makro tanah merupakan parameter yang dipakai untuk menguji korelasi antara faktor lingkungan dan karakteristik perkecambahan benih sebelum dan sesudah disimpan. Perbedaan asal benih atau populasi berpengaruh nyata terhadap perkecambahan benih sebelum dan setelah disimpan selama 54 bulan. Benih dari populasi Pomalaa (Sulawesi Tengah) mempunyai karakteristik perkecambahan terbaik sedangkan benih dari populasi Ogan Kemiring Ilir (Sumatera Selatan) mempunyai karakteristik perkecambahan terendah. Berdasarkan tingkat kadar air dan daya simpannya, benih jabon putih dapat dikategorikan sebagai benih ortodoks yang mampu disimpan lama pada suhu dan kadar air rendah. Sebagian besar faktor geo-klimat dan unsur makro tanah tidak berkorelasi nyata dengan perkecambahan benih baik sebelum maupun setelah disimpan. Hasil penelitian ini me...
