A plant phenotyping approach was applied to evaluate growth rate of containerized tree seedlings during the precultivation phase following seed germination. A simple and affordable stereo optical system was used to collect stereoscopic red-green-blue (RGB) images of seedlings at regular intervals of time. Comparative analysis of these images by means of a newly developed software enabled us to ...

Forest community structure may be influenced by seedling density dependence, however, the effect is loosely coupled with population dynamics and diversity in the short term. In the long term the strength of conspecific density dependence may fluctuate over time because of seedling abundance, yet few long-term studies exist. Based on 11 years of seedling census data and tree census data from a 2...

Low seedling quality is a pervasive problem for smallholder forestry in the Philippines. Intervention measures to improve seedling quality are being examined in a research project funded by the Australian Centre for International Agricultural Research. Field trials have been established as part of this ‘seedling enhancement project’ to compare performance on outplanting of Gmelina arborea when ...

Anthropogenic habitat deterioration can promote changes in plant mating systems that subsequently may affect progeny performance, thereby conditioning plant recruitment for the next generation. However, very few studies yet tested mating system parameters other than outcrossing rates; and the direct effects of the genetic diversity of the pollen received by maternal plants (i.e. correlated pate...

This experiment was carried out in Islamic Azad university (Shoushtar Branch) for investigate effect of salt stress on seedling growth of soybean cultivars. The soybean cultivars (Hill, Klark and Williams) obtained from Iran seed and plant institute, Karaj, Iran. The experimental design was 2 factorial, arranged in completely randomized design with 4 replication. First factor was soybean cultiv...

The text is intended for biologists and ecologists working with wild plant species. article draws attention to possible methodological inaccuracies in determining seed germination various attempts manipulate the seeds of difference between laboratory (in field), basic principles collection or selection, selection test sample, parameters related (seed germination, rate, mean time, index), initia...
