“…Studi perbedaan parameter buah dan benih antar populasi telah banyak dilakukan pada jenis-jenis tanaman hutan seperti Trigonobalanus doichangensis di China (Zheng, Sun, Zhou, & Coombs, 2009), Pinus wallichiana di India (Rawat & Bakshi, 2011), Jatropa curcas di India (Gairola, Sharma, & Dwivedi, 2011). Abies nordmanniana di Western Black Sea Region, Turki (Sevik, Yahyaoglu, & Turna, 2012)Cedrus deodara di Jammu dan Kashmir (Mughal & Thapliyal, 2012), Senna siamea di Thailand (Takuathung, Pipatwattanakul, & Bhumibhamon, 2012), dan Anthocephalus cadamba (Sudrajat, 2016). Penelitian-penelitian tersebut menunjukkan adanya keragaman morfo-fisiologi buah dan benih antar populasi sebagai parameter awal untuk mengidentifikasi keragaman genetik dan karakterisasi sifat-sifat morfologi yang membedakan populasi satu dengan yang lainnya.…”

Suren (Toona sinensis) is a potential multipurpose species that is more cultivated at upland community forests, especially in Java and Sumatra islands. This research was aimed to assess the variation of fruit and seed morpho- ABSTRAKSuren (Toona sinensis) merupakan jenis potensial multiguna yang banyak dibudidayakan di hutan rakyat dataran tinggi, khususnya di Pulau Jawa dan Sumatera. Tujuan penelitian ini adalah untuk mengkaji keragaman morfofisiologi buah dan benih dan untuk mengetahui besarnya kontribusi faktor geoklimat dan genetik terhadap karakteristik morfo-fisiologi buah dan benih suren. Benih dikumpulkan dari tujuh populasi di Sumatera Barat, Jambi, dan Jawa Barat pada bulan Maret-Mei 2015. Parameter morfologi yang diukur adalah ukuran dan berat buah dan benih, sedangkan parameter fisiologi yang diukur adalah perkecambahan dan daya simpan benih. Analisis ragam menunjukkan perbedaan morfo-fisiologi buah dan benih yang nyata antar populasi untuk semua parameter yang diuji. Populasi Cimalaka memberikan kualitas benih yang lebih baik dibandingkan dengan kualitas benih dari populasi lainnya, terutama untuk parameter fisiologi benih. Sebagian besar parameter tidak berkorelasi dengan faktor-faktor geoklimat, kecuali untuk jumlah benih hampa yang berkorelai negatif dengan suhu rata-rata tahunan tempat tumbuh, dan lebar sayap benih yang berkorelasi dengan ketinggian tempat tumbuh. Ragam genotipe dan koefisien ragam genotipe untuk semua parameter buah dan benih ditemukan lebih tinggi daripada ragam lingkungan dan koefisien ragam lingkungan yang memberi indikasi bahwa genotipe mampu menerangkan sebagian besar keragaman untuk parameter-parameter tersebut. Nilai heritabilitas yang berpasangan dengan kemajuan genetik yang tinggi ditemukan pada parameter daya dan kecepatan berkecambah. Analisis komponen utama terhadap parameter buah dan benih menunjukkan bahwa populasi-populasi yang berdekatan secara geografik mempunyai kedekatan secara genetik.

“…Firs reproduce sexually via seeds. Consequently, their commercial production depends on seed viability and quality [13,14]. Previous research [15][16][17][18][19][20] shows that germination efficiency is significantly affected by seed mass.…”

Research Highlights: The correlations between seed mass and the remaining physical properties were determined in selected fir species, and a method for seed sorting was proposed to promote uniform germination and emergence. Background and Objectives: Information about the variation and correlations between the physical properties of seeds is essential for designing and modeling seed processing operations such as seed separation. The aim of this study was to determine the range of variation in the physical properties of seeds in eleven fir species, and to analyze the correlations between these parameters to improve the seed sorting process. Materials and Methods: Terminal velocity, thickness, width, length, the angle of external friction and mass were determined in the seeds of 11 fir species. The measured parameters were used to calculate the geometric mean diameter, three aspect ratios, sphericity index and the specific mass of each seed. Results: The seeds of Sierra white fir where most similar, whereas the seeds of balsam fir differed most considerably from the seeds of the remaining fir species. In the majority of the analyzed fir species, seed mass was most strongly correlated with terminal velocity, followed by thickness. Conclusions: Fir seeds should be sorted primarily with the use of mesh sieves with longitudinal openings to obtain fractions with similar seed mass and to eliminate the need for dewinging.

“…Despite those high interests of D. guineense to populations, we do not know much about how its spatial distribution could be impacted by climate change and which strategies to implement for its sustainable use and conservation in West Africa [our landscape of interest (LOI)] and particularly in Benin. In order to achieve that purpose, this study aimed at addressing the following research questions: in the context of climate change, under different scenarios (IPCC, 2013);(i) what is the extent of stable (suitable both at present and in the future) areas for the spatial distribution of D. guineense? (ii) What is the extent of unsuitable (both at present and in the future) areas for the spatial distribution of the species?…”

Dialium guineense is a multipurpose species useful in many respects. It is used in agroforestry and the trade of most of its organs is source of income for rural populations. Despite the high interests of this species to populations, we do not know much about how its spatial distribution could be impacted by climate change and which strategies to implement for its sustainable use and conservation. In order to overcome these challenges, MaxEnt was used to model the ecological niche of D. guineense and different decision thresholds w ere used to interpret and classify the outputs. Climate will impact the distribution of D. guineense. Indeed under Africlim rcp 4.5 horizon 2055, the predicted stable areas of species distribution will be about 73% of West Africa when the threshold of the minimum training presence is considered and will decrease to 12% when the threshold of the maximum training sensitivity plus specificity is considered. Under Africlim 8.5 horizon 2055, the corresponding values for the stable areas of the species are, respectively 70 and 8% of the study area. In comparison with the global results of West Africa, in Benin, D. guineense will be less threatened by climate change. As strategies for sustainable use and conservation of the species, growing and introducing it in its favorable areas to account for its absence or low densities, is recommended. Also, building capacities to the users of the species so that they can grow it on their farms is recommended.
