“…Seed germination and seedling emergence are critical phases in the development of plants and this implies that seed vigour is an important trait for the selection of important crop cultivars [3,4]. The capacity of a seed to germinate quickly and competitively depends on the genetic and physiological constitution of the seed [5,6]. In addition, seed size at maturity is an important physical indicator of seed quality which can affect vegetative growth and is frequently related to yield [1].…”

Origin-dependence of variation in seed morphology, mineral composition and germination percentage in Gynandropsis gynandra (L.) Briq. accessions from Africa and Asia

Background: Spider plant [Gynandropsis gynandra (L.) Briq.], an economically promising African leafy vegetable, characterized for leaf yield components and nutritive quality, exhibits poor seed germination that hinders a wider expansion of the crop in urban and periurban horticultural systems. So far, there is little information pertaining to seed morphological traits and mineral elements content that may be associated with higher seed germination. This research investigated the hypothesis that spider plants from different geographical areas exhibited differences in seed mineral composition, morphological traits, and germination capacity. To this end, twenty-nine accessions of Gynandropsis gynandra from West and East-Southern Africa, and Asia were screened for variation in seed size (area, perimeter, length, width), 10-seed weight, mean germination time, germination percentage and mineral content variations. The scanning electron microscopy (SEM), light microscopy and energy dispersive spectroscopy (EDS) solution were used to study seed morphology and mineral composition. Results: We show for the first time the external and internal structure of the seeds of Gynandropsis gynandra and measured eight mineral elements, including carbon (C), oxygen (O), magnesium (Mg), aluminium (Al), phosphorus (P), sulphur (S), potassium (K) and calcium (Ca). The accessions differed significantly (p < 0.001) with respect to seed size (area, perimeter, length, width), 10-seed weight, mean germination time and germination percentage. The hierarchical cluster analysis based on fourteen variables grouped the accessions into three distinct clusters, partially dependent on their geographical origin. Asian accessions exhibited smaller seeds and recorded higher values in terms of germination percentage. West African accessions had bigger seeds but with lower germination percentage. Variation in minerals such as potassium, carbon, and calcium content showed different patterns according to geographical origins.(Continued on next page)

“…Kashyap et al (1994) found significant differences among different cultivars and period of storage of wheat seed for all parameters of viability and vigour. There were significant differences in viability and vigour of soybean, rice, sesame and kenaf during storage (Thseng et al, 1996;Nkang and Umah 1996;Kamaswara and Jackson, 1996;Adebisi and Ajala, 2000;Adebisi et al, 2013a). Harrington (1972) reported that germination and vigour in crop decreased as storage time and relative humidity increased.…”

Longevity and vigour of pigeon pea (Cajanus cajan (L.) Millsp.) seed stored under humid tropical ambient conditionsAbstract: Seeds of 20 pigeon pea (Cajanus cajan (L.) Millsp.) genotypes were evaluated for seed longevity and vigour under humid ambient conditions. Cleaned seeds of each genotype were packed into a polyethylene bag, the packaged lot was electrically sealed and thereafter placed in a seed store under ambient conditions (30 ºC, RH 75 %). Seed samples were withdrawn at 0, 60, 120, 180 and 240 days after storage for seed quality parameters evaluation. The experiment consisted of two factors which were genotype and storage duration and was a laid out in a completely randomized design with three replications. Data were collected on rate of seed germination, seed viability, seedling length, seedlings fresh mass, seedlings dry mass and seedling vigour index. Data collected were subjected to analysis of variance and significant treatment means were separated using Tukey's HSD test at 5 % probability level. PROBIT modelling was also used to predict the seed longevity of stored pigeon pea. Significant differences were observed in all seed quality attributes evaluated among the 20 pigeon pea genotypes and storage time except seedling fresh mass. Seed quality attributes decreased significantly with increasing storage periods. Genotypes NSWCC-18A, NSWCC-24, NSWC-34 and NSWCC-29A were identified to be superior for most of the seed quality attributes evaluated. PROBIT modelling result revealed that genotype NSWCC-29b had the highest storage life (16.28 months) and the highest storage potentials in terms of seed viability and other seed quality attributes of all seed lots. Dolgoživost in vitalnost semen kajana (Cajanus cajan (L.) Millsp.) shranjenih v vlažnih tropskih razmerahIzvleček: Dolgoživost in vitalnost semen 20 genotipov kajana (Cajanus cajan (L.) Millsp.) sta bili ovrednoteni v vlažnih tropskih razmerah. Očiščena semena vsakega od genotipov so bila shranjena v zaprte polietilenske vrečke, ki so bile nameščene v hrambo semen pod okoljskimi razmerami (30 ºC, RH 75 %). Vzorci semen so bili odvzeti po 0, 60, 120, 180 in 240 dnevih za ovrednotenje parametrov kakovosti. Poskus je bil dvofaktorski, kjer je bil prvi dejavnik genotip, drugi pa trajanje hrambe in je bil izveden kot popolni naključni poskus s tremi ponovitvami. Zbrani so bili podatki o kalivosti semen, njihovi viabilnosti, dolžini sejank, sveži in suhi masi sejank in njihovem vitalnostnem indeksu. Podatki so bili ovrednoteni z analizo variance, poprečja značilnih obravnavanj so bila ločena s Tukeyevim HSD testom pri verjetnosti 5 %. Za predvidevanje dolgoživosti shranjenih semen kajana je bil uporaben PROBIT model. Ugotovljene so bile značilne razlike v vseh ovrednotenih kakovostnih parametrih semen med vsemi 20 genotipi kajana in med časi hrambe, z izjemo sveže mase sejank. Kakovostni parametri semen so se s časom shranjevanja značilno zmanjševali. Genotipi NSWCC-18A, NSWCC-24, NSWC-34 in NSWCC-29A so bili prepoznani kot najboljši v vseh ovrednotenih...

“…One aspect of great relevance in the accelerated aging test is the seed size, being one of the quality components that most affects crop performance (Adebisi et al, 2013). Effects of seed size have been observed on seed germination, seedling emergence and related agronomic aspects in many crop species, including Amaranthus cruentus L. (Kaydan and Yagmur, 2008).…”

The use of vigor tests for assessing seed lot quality is an important tool for production and commercialization. However, research on evaluating the quality of amaranth seeds is still scarce. The objective of this work was to evaluate procedures for conducting the accelerated aging test, aiming at the identification of different levels of vigour among lots of amaranth (Amaranthus cruentus L.) seeds cultivar BRS Alegria. Five seed lots were used and submitted to tests of germination, first count of germination, seedling emergence and accelerated aging, using the aging periods of 24, 48 and 72 hours and adopting the traditional methodology with water and the use of saturated (40g NaCl in 100mL of water) and unsaturated (11g NaCl in 100mL of water) sodium chloride (NaCl) solution. The accelerated aging test at 41ºC and periods of 24, 48 and 72 hours of conditioning saturated NaCl solution allowed the stratification of the lots at vigour levels, similar to the results obtained by the seedling emergence test and the first count of germination. The accelerated aging test, using saturated saline solution (40g NaCl in 100mL of water) for 24 hours at 41°C, is therefore suitable for evaluating the physiological potential of amaranth seeds.
