“…As in the case of rosette leaf number, the correlation was not significant in our small sample size (P < 0.35). Nevertheless, the trend was consistent with previous studies that showed intraspecific selection for rapid germination can lead to an increase in seed size and evolution of invasiveness (Graebner et al 2012;Tanveer et al 2013;Torices et al 2013). Given that ecological studies on germination speed have suggested a strong relationship with seed size and competitiveness (Dubois & Cheptou 2012;Lonnberg & Eriksson 2013;Afonso et al 2014;Leverett & Jolls 2014), our finding may suggest that the competitiveness of larger seeds is partly mediated by rapid germination.…”

Seed germination is a key life history transition for annual plants and partly determines lifetime performance and fitness. Germination speed, the elapsed time for a nondormant seed to germinate, is a poorly understood trait important for plants' competitiveness and fitness in fluctuating environments. Germination speed varied by 30% among 18 Arabidopsis thaliana populations measured, and exhibited weak negative correlation with flowering time and seed weight, with significant genotype effect (P < 0.005). To dissect the genetic architecture of germination speed, we developed the extreme QTL (X-QTL) mapping method in A. thaliana. The method has been shown in yeast to increase QTL mapping power by integrating selective screening and bulk-segregant analysis in a very large mapping population. By pooled genotyping of top 5% of rapid germinants from ~100 000 F3 individuals, three X-QTL regions were identified on chromosomes 1, 3 and 4. All regions were confirmed as QTL regions by sequencing 192 rapid germinants from an independent F3 selection experiment. Positional overlaps were found between X-QTLs and previously identified seed, life history and fitness QTLs. Our method provides a rapid mapping platform in A. thaliana with potentially greater power. One can also relate identified X-QTLs to the A. thaliana physical map, facilitating candidate gene identification.

Knowledge of the effects of seed burial depth and the presence of straw on the soil surface on weed seedling emergence provides useful information for the development of weed management tactics. Buttonweed (Borreria densiflora DC.) is a troublesome weed that occurs in large infestations in soybean and sugarcane crops from north-central Brazil. This study investigated buttonweed emergence at different seed burial depths and straw amounts present on the soil surface. The experiment was conducted in greenhouse conditions, under a factorial design between four seed burial depths and four amounts of surface straw. Percent seedling emergence and fresh biomass (g) were evaluated at twenty-five days after installation (DAI). Greater buttonweed emergence occurred in seeds that were placed on the soil surface either without surface straw or with up to 1,000 kg ha −1 of straw on the soil surface. With 4,000 kg ha −1 of surface straw, buttonweed emergence was prevented when seeds were placed at a depth of 0.5 cm or deeper in the soil. These data indicated emergence of this weed species was greater at depths near the soil surface and in soils with the least amounts of surface straw. Information generated in this study provides a starting point for the development of knowledge for understanding the biology of buttonweed emergence and its population dynamics. Such information may be directly transmitted to growers and lays the groundwork for an integrated management approach for this weed species.

“…The soil is an environmental factor that also determines plant growth which is influenced by the organism, climate, topography, time and parent material (Hoveizch 1997). There are many soil factors (variables) that influence the diversity and distribution of plant species, such as organic matter, exchangeable cation, soil types and other soil factors Tanveer et al (2013) suggest that the Celosia arvensis tends to grow better in neutral and slightly acidic soil as compared to alkaline soil environments.…”

Sofiah S, Sulistyaningsih LD. 2019. The diversity of Smilax (Smilacaceae) in Besiq-Bermai and Bontang Forests, East Kalimantan, Indonesia. Biodiversitas 20: 279-287. The genus Smilax has taxonomic complexity problems and spacious distribution. Taxonomic study to reveal the diversity of Smilax species had been done in some regions, such as America, China, Japan, Thailand, and Indonesia. However, there is lack of information of Smilax species diversity in Kalimantan especially in East Kalimantan which lies in Sundaland biogeographic. This study was carried out to explore and record the diversity of Smilax species including the ecological and environmental data in Besiq-Bermai and Bontang forests in East Kalimantan, Indonesia. This research conducted on February and August in 2012 and July-August 2015 using exploration methods. Purposive random sampling was used to do the botanical sampling. The principal component analysis (PCA) was performed to determine the relationships between environmental components and Smilax species occurrences. There were five species of Smilax which were housed in those forests in East Kalimantan, namely, Smilax leucophylla Blume, Smilax gigantea Merr., Smilax odoratissima Blume, Smilax zeylanica L., and Smilax modesta A.DC. Smilax leucophylla and Smilax zeylanica are the most widely used by the local people for medicine. The taxonomic description, distribution, use, and vernacular name were given. The environmental factors that contribute significantly to Smilax's growing environment are temperature and light intensity.
