Maturation curves and degree-days accumulation for fruits of 'Folha Murcha' orange trees Curvas de maturação e graus-dia acumulados para frutos de plantas de laranjeira 'Folha Murcha'

Scientia Agricola, 2006
The effect of thermal summation on orange fruit growth on different rootstocks has not been studied for the State of Paraná, Brazil. This research evaluated the growth of fruits by means of maturation curves, and quantified the growing degree-days (GDD ...

Incentives and constraints for the use of organic seeds in organic farming: example of Capsicum annuum seeds in the Netherlands and Spain [PDF]

, 2017
The EU legislation on organic farming was aimed at forcing the use of organic seeds in organic production. However, there are striking differences in its implementation across the EU and the use of organic seeds is still sparse.

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Yield Response of Grafted and Self-Rooted Tomato Plants Grown Hydroponically under Varying Levels of Water Salinity

Agronomy
To overcome the scarcity of fresh water, researchers have turned to investigating different techniques that enable using saline water to irrigate crops, aiming to increase the efficiency of using available water resources.

Environmental influence on intraspecific trait variation in the tropical seagrass Halodule uninervis

Oikos, EarlyView.
Intraspecific trait variation (ITV) enhances the precision of applying functional trait approaches in plant ecology. Despite its benefits, ITV is rarely considered in functional trait‐based seagrass research. The goal of our research is to measure ITV in the tropical seagrass species Halodule uninervis and assess the environmental factors associated ...

Physiological and Biochemical Responses of Almond (Prunus dulcis) Cultivars to Drought Stress in Semi-Arid Conditions in Iran

Plants
Identifying and selecting almond cultivars with drought tolerance traits is crucial for developing more resilient cultivars, especially in regions prone to water scarcity or facing changing climate conditions.

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Response of potential cucurbit rootstocks against Meloidogyne spp [PDF]

, 2014
the Cucurbita hybrids, usually used as cucurbit rootstocks, are susceptible to Meloidogyne. Its cultivation increases the nematode population densities at similar levels than ungrafted cucumber or melon crops, and higher 'Ievels than watermelon ...

CALIFORNIA CITRUS ROOTSTOCKS

HortScience, 1993
Though California is currently not facing the intense disease pressure that led to the development of the Troyer and Carrizo citrange rootstocks (sweet orange × trifoliate orange hybrids) that replaced the sweet orange (Citrus sinensis [L.] Osbeck) rootstocks, the California industry is still actively involved in breeding and evaluating rootstocks.All ...
