Stigma structure and receptivity in Bromeliaceae

Scientia Horticulturae, 2016
Abstract Morphoanatomical characterization of the stigma of different species has provided important data for the taxonomy of Bromeliaceae. Stigma receptivity is fundamental for the effectiveness of reproduction in plants, and the production of hybrids by controlled pollination. This study aimed to characterize stigma morphoanatomy of 18 Bromeliaceae

Stigma-surface Esterase Activity and Stigma Receptivity in Some Taxa Characterized by Wet Stigmas

Annals of Botany, 1981
Stigma-surface esterase activity and stigma receptivity through a sequence of developmental stages of the pistil have been studied in four taxa characterized by having wet stigmas-Petunia hybrida, Nicotiana tabacum, Crinum defixum and Amaryllis vittata. The style is solid in the first two and hollow in the latter two taxa.

Pollen viability and stigma receptivity in Lilium during anthesis

Euphytica, 2017
Pollen viability and stigma receptivity are prerequisites for successful pollination and seed set in flowering plants. In this study, the pollen viabilities and stigma receptivities of nine Lilium genotypes (six cultivars and three species native to China) were assayed by in vitro pollen germination and the benzidine-H2O2 method, respectively.

Effective pollination period as related to stigma receptivity in apricot

Scientia Horticulturae, 1992
Abstract In the warm climatic conditions of the south Mediterranean area, where mean temperatures during blooming period are as high as 15–18°C and maximum temperatures frequently exceed 25°C the effective pollination period (EPP) of apricot cultivars is extremely short.

Pollen viability, stigma receptivity and seed set in Viola tricolor

2011 International Conference on Electrical and Control Engineering, 2011
Pollen viabilities and stigma receptivities of 19 accessions in Viola tricolor were assayed by in vitro pollen germination and benzidine-H 2 O 2 method in this paper respectively. The seed set through hand-pollinate selfing was also investigated. The results showed that the pollen germination percent of V.

The Receptive Surface of the Angiosperm Stigma

Annals of Botany, 1977
This paper reports upon a study of the characteristics of the receptive surfaces of angiosperm stigmas, covering almost 1000 species of about 900 genera of some 250 families. In both monocotyledons and dicotyledons the major subdivision is into those stigmas which are 'dry' at maturity, having a hydrated, proteinaceous extracuticular layer or pellicle ...

Elemental and biochemical markers of stigma receptivity in sunflower

Acta Physiologiae Plantarum, 2014
Stigma development in sunflower is accompanied with an accumulation of calcium (33 %), potassium (37 %) and boron (62 %) in mature stigma as compared to stigma at bud stage, thereby demonstrating their essential roles in attaining receptivity. Membrane-bound calcium accumulation is enhanced on the pellicle and is also evident in the cytoplasm ...

Stigma Receptivity and Seed Set in Protogynous Buffelgrass

Crop Science, 2000
Buffelgrass, Pennisetum ciliare (L.) Link syn = Cenchrus ciliaris L., is an important warm‐season perennial forage grass that is widely grown throughout the arid tropics. It has perfect florets, and emasculation is thought to be required to produce controlled hybrids. This is a tedious, difficult undertaking because of the small floret size.

THE PERIOD OF RECEPTIVITY OF RICE STIGMA

Madras Agricultural Journal, 1933
A knowledge of the natural pollination and fertilisation in cultivated crops is of extreme importance to the plant breeder in the matter of evolving successful techniques of artificial hybridisa- tion for crop improvement. In most of the crop plants, which are self fertilised, natural pollination occurs at the time of flower opening.
