“…The seeds of silver fir were somewhat larger than those analyzed [43] and Kaliniewicz et al [41], but their dimensions were within the range of average values noted in Poland [29]. The evaluated seeds were similar to selected batches of Normann fir seeds in terms of length [27,45], and they were similar to pindrow fir seeds in terms of length and width [46]. The analyzed Korean fir seeds were approximately 10% larger than those studied by Song et al [47].…”

Research Highlights: The correlations between the analyzed physical properties of seeds and seed mass were determined. The results were analyzed to determine most effective seed separation devices for the evaluated fir species. Background and Objectives: Information about the variations 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 variations in the basic physical properties of seeds of selected fir species, and to identify the correlations between these attributes for the needs of the seed sorting processes. 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 average values of the basic physical properties of the analyzed seeds were determined in the following range: terminal velocity – from 4.8 to 7.1 m s-1, thickness – from 1.76 to 3.22 mm, width – from 3.29 to 5.57 mm, length – from 5.44 to 11.06 mm, angle of external friction – from 26 to 33°, and mass – from 7.9 to 48.3 mg. 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. 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.

“…According to many authors [2,13,33,37,[40][41][42], fir seeds differ in germination capacity that can range from 0 to approximately 90% in freshly harvested seeds. The above can be attributed to the fact fir seeds are characterized by a high proportion of empty seeds [2,13,20,37,43,44], which can reach 70% in some cases.…”

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.

“…Seeds of different species and of the same species from different provenances behave differently in their germination response and the equal knowledge about this thing is very essential for understanding plantation programs (Masoodi et al 2014). Seed improvement quality is needed to get optimal germination.…”

“…Germination of a seed is the initial, and, under some circumstances, critical step in afforestation by natural or artificial means. Similarly, a species may be found in a wide variety of climatic regions, but the germination behavior may differ according to provenance (Masoodi et al 2014). Benech-Arnold and Sanchez (eds.)…”

Abstract. Purwantoro RS. 2017. Seed germination and seedling growth of Chiococca javanica (Rubiaceae) in relation to fruit maturation and media growth. Nusantara Bioscience 9: 111-119. Chiococca javanica is a plant having ornamental potential. The seeds extracted from the fruits were classified according to maturity stage: Unripe -yellow; ripe -reddish; and over ripe -dark-red and seed germination were done in two germination media: sand and rice husk. The statistical approach was a randomized complete block design with three replications. Analysis of variance indicated that the seeds of C. javanica from the ripe and over ripe fruit had higher significances (P<0.05) on germination capacity, speed of germination, mean germination time, mean daily germination, peak value and germination value than the seeds from yellow fruits. The effect of growing media on germination process showed higher significance in sand than that in rice husk. Similarly, mean daily germination in sand was higher than that in rice husk. All seedling growth parameters of the seeds from ripe and over ripe fruit showed significant different on number of leaves, shoot length, diameter of seedlings, number of lateral roots, roots length, fresh weight and dry weight of plants than the seeds from unripe fruit.
