“…Both populations presented a weak association between the variables ( Figure 4). Other studies, with another species from Fabaceae, also did not find associations between seed weight and seedling vigor [5], [46]. Seedling survivor and faster germinations associated with seed weight were also not observed [4].…”

“…Bigger seeds have greater food supplies, which could result in greater initial growth rates [1]- [4]. In order to identify the best propagation methods, seed size and weight have been used to identify seed lot quality in several plant species [1], [4], [5]. Some studies have shown that biometrics of seeds could be used as an indirect parameter to propitiate grater and homogenous germination, and also favoring the germination of the embryo resulting in the most vigorous seedlings [1], [4], [6].…”

Morphological integrations are unknown to forestry seeds. Understanding if seed measurements could predict its future seedlings features is a central question in seedling production. Hymenaea courbaril is an important species in this context and to the applied forestry.Thus, this study aimed to understand how some seedling features, could be related to the seed weight, and be affected by the population origin. The measurements consisted of seedling collar diameter, weight, protophilus area, central and lateral vein. Seed weight consistently varied between the populations in the study. Both populations had higher weight ranges than mentioned in the literature. There was no strong evidence that greater seed weight requires lesser time to germinate, conflicting with previous information. All the measurements presented enough shreds of evidence to be considered different when comparing the populations, except for the protophilus area and lateral vein length. All the studied measurements presented low correlation indexes to seed weight, except for seedling collar diameter, and seedling weight, which presented a moderate correlation. Protophilus elongation pattern was strongly associated with the leaf width when compared to midvein.

“…Desired soil moisture was maintained using water up to ten days. The seedlings emergence was considered just after coming out of cotyledons above the soil surface (Mishra et al, 2014). For the judgment of growth and dry weight, 10 randomly selected seedlings from each replication were harvested from each Petri dish.…”

“…The effect of seed size on seedling vigour and seed yields has recently been reviewed by Ambika et al (2014). Large seeds generally help in producing better seedling compared to medium and/or small sized seeds due to sufficient energy content in large seeds (Mishra et al, 2014). Nevertheless, heavy-weighted seeds help in producing better performance on seed germination, survival and initial seedling growth compare to light seeds (Upadhaya et al, 2007;Singh and Sexena, 2009;Sadeghi et al, 2011).…”

Germination and seedling growth of Sesbania species as influenced by seed size

et al. 2018

An experiment was carried out at Plant Systematics Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh to find out the effect of seed size on germination and seedling growth of three Sesbania species. Seed size was graded as small (3.1–3.5 mm), medium (3.6–4.0 mm) and large (4.1–4.5 mm); and three Sesbania species viz. S. bispinosa, S. cannabina and S. sesban, were used as experimental materials. The treatments were arranged in factorial experiment laid in completely randomized design having four replications. Though the effect of seed size on germination and seedling growth parameters followed similar trend, significant differences were observed among these three Sesbania species. Medium-sized seed produced the highest percentage of emergence and germination, and large-sized seed produced the highest seedling length, vigour index, and total biomass; although the numerical values did not differ statistically. The small-sized seeds were poor performer in all aspect of germination and seedling growth descriptors. The correlation matrix analyses showed that seed size, both length and/or width, highly correlated with root and seedling length, base diameter, vigour index and biomass yield of Sesbania spp. The medium to large-sized seed sown at relatively higher seed rate could be helpful for higher biomass yield of Sesbania spp. especially at the early growth stages.Progressive Agriculture 28 (4): 316-322, 2017

“…The shoot-root ratio is important for establishment, growth and survival of seedling. Mishra et al (2014) reported that the root-shoot ratio is used to assess the overall health of plants. Nevertheless, the vigour index ranged from 1731-384 with an average value of 1217 (Table 1).…”
