Influence of flower functionality and pollination system on the pollen size-pistil length relationship
(Elsevier Gmbh, 2009-05)
Twenty-five biotically pollinated plants of the Chaco Serrano Forest (Córdoba, Argentina) were studied in order to analyze whether ‘flower functionality’ is related to the relationship between pollen size and pistil length. ...
Pollen size and pistil length variation: the influence of flower-functionality and pollination system
(Springer Heidelberg, 2009-06-25)
Twenty-five biotically pollinated plants of the Chaco Serrano Forest (Córdoba, Argentina) were studied in order to analyze whether ‘flower functionality’ is related to the relationship between pollen size and pistil length. ...
High temperatures during late floral bud stages decrease fertilization in strawberry (Fragaria ₓ ananassa): pollen-pistil interaction and anatomical evidences
High temperature (HT) effects on pistil tissues and female gametophyte have been scarcely investigated in crops species. During strawberry flowering, HT can induce fruit malformations due to poor pollen performance in ...
Flower and seed production as affected by axis category and shoot size in two patagonian nothofagus species
(National Research Council Canada-NRC Research Press, 2012-04-21)
Flower distribution within the tree crown may affect both pollination dynamics and the costs of flowering on tree growth. For Nothofagus obliqua (Mirb.) Oerst. and Nothofagus nervosa (Phil.) Krasser, the production of ...

Autophagy is associated with male sterility in pistillate flowers of Maytenus obtusifolia (Celastraceae)
(Csiro Publishing, 2018-01-01)
Programmed cell death (PCD) is defined as a sequence of genetically regulated events leading to controlled and organised cellular degradation. It plays a vital role in plant development; however, little is known about the ...
