Clone variation of seed traits, germination and seedling growth in Dalbergia sissoo Roxb. clonal seed orchard

open access: yesAnnals of Forest Research, 2013
A clonal seed orchard (CSO) of Dalbergia sissoo Roxb. at Hoshiarpur, India consisting of 20 clones originating from different agro-climatic conditions of four northern states (Uttar Pradesh, Rajasthan, Haryana and Uttarakhand) was the source of seeds for

The method for breeding and genetic assessment of Scotch pine clones at forest seed orchards [PDF]

open access: yesСибирский лесной журнал, 2016
Fast height growth selection usually considered as the basic type of Scotch pine breeding strategy. Due to this fact height growth of pine clones usually is taken as the first key feature.

Regeneration in gap models: priority issues for studying forest responses to climate change [PDF]

open access: yes, 2001
Recruitment algorithms in forest gap models are examined with particular regard to their suitability for simulating forest ecosystem responses to a changing climate. The traditional formulation of recruitment is found limiting in three areas.

Planting the seeds for a forest of RNAi pathways

open access: yesPLOS Biology, 2023
Cells from most eukaryotic species make several different types of small interfering RNAs. Pioneering work in plants, published in PLOS Biology almost 20 years ago, established a framework to understand how multiple RNA interference pathways can regulate the genome in parallel.

Growth characteristics and saponin content of mountain-cultivated ginseng (Panax ginseng C. A. Meyer) according to seed-sowing method suitable for cultivation under forest

open access: yesForest Science and Technology, 2020
Mountain-cultivated ginseng (MCG) is a very important health functional material in Korea and the USA. In this study, the growth and saponin of MCG change according to the sowing method were investigated.

Securing access to seed: social relations and sorghum seed exchange in eastern Ethiopia [PDF]

open access: yes, 2008
Access to seed is crucial for farming, though few studies investigate household-level access in the informal ‘farmer seed systems’ which still supply most seed in poor countries.

Seed Yield and Morphological Variations of Beechnuts in Four European Beech (Fagus sylvatica L.) Populations in Croatia

open access: yesSouth-East European Forestry, 2018
Background and Purpose: Since the last decade, the amount and periodicity of European beech seed crops in Croatia have been disrupted, and thus the regeneration of its forests has become increasingly questionable. The aim of this study was to determine: (

Long Distance Seed Dispersal by Forest Elephants [PDF]

open access: yesFrontiers in Ecology and Evolution, 2021
By dispersing seeds long distances, large, fruit-eating animals influence plant population spread and community dynamics. After fruit consumption, animal gut passage time and movement determine seed dispersal patterns and distances. These, in turn, are influenced by extrinsic, environmental variables and intrinsic, individual-level variables.
