The plant age influences eggplant fruit growth, metabolic activity, texture and shelf-life
(Elsevier Science, 2020-10)
Vegetable quality shows extensive variation along a single production cycle depending on the harvest season. So far, these effects have been mostly attributed to variations in preharvest climatic conditions, resource ...
Conservation values of understory vascular plants in even- and uneven-aged Nothofagus antarctica forests
(Springer, 2020-09)
Usually, stands with aging trees are considered forests with higher conservation values, regardless their structural diversity and other functional attributes. Natural stands present a wide range of age structures, from ...
Plant and herbivore ontogeny interact to shape the preference, performance and chemical defense of a specialist herbivore
(Springer, 2018-06-30)
The amount of damage that herbivorous insects impose on plants varies as a function of plant ontogenetic trajectories in tissue quality and defenses, and the herbivores’ own developmental trajectories in body size, mandible ...
The interplay between ovule number, pollination and resources as determinants of seed set in a modular plant
(PeerJ, 2018-07-31)
Background. A classical dichotomous perspective proposes that either pollination or plant resources limit seed production. However, ovule number could also be limiting when pollination results in complete ovule fertilization ...
Ectomycorrhizal fungal communities in Nothofagus nervosa (Raulí): A comparison between domesticated and naturally established specimens in a native forest of Patagonia, Argentina
(Elsevier, 2015-12)
Due to its overexploitation during the past century, Nothofagus nervosa is currently included in conservation and domestication programs, in which ectomycorrhizas play an important role. We aimed to describe the abundance ...
Expression of a plastid-targeted flavodoxin decreases chloroplast reactive oxygen species accumulation and delays senescence in aging tobacco leaves
(Frontiers Research Foundation, 2018-07)
Leaf senescence is a concerted physiological process involving controlled degradation of cellular structures and reallocation of breakdown products to other plant organs. It is accompanied by increased production of reactive ...
Salicylic acid determines differential senescence produced by two turnip mosaic virus strains involving reactive oxygen species and early transcriptomic changes
(2013-12)
Losses produced by virus diseases depend mostly on symptom severity. Turnip mosaic virus (TuMV) is one of the most damaging and widespread potyvirus infecting members of the family Brassicaceae, including Arabidopsis ...
Fire influences the structure of plant–bee networks
(Wiley Blackwell Publishing, Inc, 2017-10)
Fire represents a frequent disturbance in many ecosystems, which can affect plant–pollinator assemblages and hence the services they provide. Furthermore, fire events could affect the architecture of plant–pollinator ...
Native plant naming by high-school students of different socioeconomic status: implications for botany education
(Routledge, 2018-01)
People’s diminished awareness of plants, affected by anthropogenic environmental deterioration, has challenged science education to overcome the obstacles impeding a better understanding of their meaning and value. The aim ...
A new Late Triassic age for the Puesto Viejo Group (San Rafael depocenter, Argentina): SHRIMP U-Pb zircon dating and biostratigraphic correlations across southern Gondwana
(Pergamon-Elsevier Science Ltd, 2014-12)
The Puesto Viejo Group crops out in the San Rafael Block, southwest Mendoza, at approximately 35° S and 68°20' W. It consists of the basal mainly grayish Quebrada de los Fósiles Formation (QF) overlying by the reddish Río ...
