Determinação da Distância de Dispersão Efetiva de Cabralea canjerana

Floresta e Ambiente
Objetivou-se conhecer a distância de dispersão efetiva de Cabralea canjerana (Vell.) Mart. em um fragmento de Floresta Estacional. Foram alocadas parcelas de 5 m × 5 m em uma área com alta densidade de indivíduos regenerantes da espécie.

Seed ecology in dry sandy grasslands - an approach to patterns and mechanisms

, 2013
Dry sandy grasslands occur throughout Central Europe and Southern Germany, and they host many rare and endangered plant species. To date, insufficient data on seed ecological aspects of this endangered vegetation type exist.

The effect of cultural and environmental factors on potato seed tuber morphology and subsequent sprout and stem development [PDF]

, 2001
Seed crops of the variety Estima were grown in each of 2 years using two planting dates, two harvest dates, two plant densities and two irrigation regimes to produce seed tubers which had experienced different cultural and environmental conditions.

Impact of Row Distance and Seed Density on Grain Yield, Quality Traits, and Free Asparagine of Organically Grown Wheat

Agronomy, 2019
Organic farming faces challenges providing sufficient nutrient supply as manure and crop rotations are often the major nutrient inputs. Larger row distances and fewer seed densities can support nitrogen availability by giving more space to the single ...

PLANT DENSITIES AND ITS EFFECT ON YIELD AND ITS COMPONENTS OF SOME FABA BEAN VARIETIES [PDF]

Journal of Plant Production, 2002
Two field experiments were conducted at Shandawill Research Station. Sohag governorate during 1999/2000 and 2000/2001 seasons. The aim of this investigation was to study the effect of three plant population density i.e 16.7, 33.3 and 50 plants/m2 on ...

Negative density dependence of seed dispersal and seedling recruitment in a Neotropical palm [PDF]

, 2014
Negative density dependence (NDD) of recruitment is pervasive in tropical tree species. We tested the hypotheses that seed dispersal is NDD, due to intraspecific competition for dispersers, and that this contributes to NDD of recruitment.

Microgreens Production: Exploiting Environmental and Cultural Factors for Enhanced Agronomical Benefits

Plants
An exponential growth in global population is expected to reach nine billion by 2050, demanding a 70% increase in agriculture productivity, thus illustrating the impact of global crop production on the environment and the importance of achieving greater ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Weed suppressive effect of common vetches in sole and intercrops with oat depending on seed density ratio and cultivar of vetch

Julius-Kühn-Archiv, 2014
Seed vetches (Vicia sativa L.) are currently grown mainly in catch crop mixtures. They are characterized by a high biomass production with a good rooting intensity and good weed suppressing effect.
