Effects of Low Temperature Stress on Spikelet-Related Parameters during Anthesis in Indica–Japonica Hybrid Rice

open access: yesFrontiers in Plant Science, 2017
Poor spikelet fertility under low temperature (LT) stress during anthesis limits the possibility of high yield potential in indica–japonica hybrid rice, leading to reduced stability of grain yield. However, the cause for it is still unclear.

QTL mapping and identification of candidate genes using a genome-wide association study for heat tolerance at anthesis in rice (Oryza sativa L.)

open access: yesFrontiers in Genetics, 2022
Heat tolerance (HT) of rice at anthesis is a key trait that ensures high and stable yields under heat stress. Finding the quantitative trait loci (QTLs) and gene loci controlling HT is crucial. We used relative spikelet fertility (RSF) as a measure of HT.

Nocturnal and diurnal pollination in Copaifera coriacea, a dominant species in sand dunes of the Middle São Francisco River Basin, Northeastern Brazil [PDF]

open access: yesPlant Ecology and Evolution, 2021
Background and aims – Copaifera coriacea, a species in the resin-producing clade Detarioideae (Leguminosae), is an endemic and abundant species found in sand dunes in Brazilian Caatinga domain vegetation – a Quaternary paleodesert. We investigated floral

Use of consumer-grade cameras to assess wheat N status and grain yield [PDF]

open access: yes, 2019
Relationships between (a) fractional Intercepted PAR (fIPAR), and (b) aboveground biomass (Biomass) and (c) grain yield at harvest with the Normalized Difference Vegetation Index (NDVI) derived either from a spectroradiometer or a conventional camera at ...

Anthesis and pollen release: anthesis and pollen release of some plants of west bengal, india [PDF]

open access: yesGrana, 1992
Abstract The pattern and quantum of daily pollen release of thirty five plants of southern West Bengal were studied by counting their nature and time of anther dehiscence in one hour time interval in relation to meteorological condition. The results have been correlated with the atmospheric concentration of pollen grains in their surrounding ...

Rice seed quality development and temperature during late development and maturation [PDF]

open access: yes, 2011
The potential longevity of japonica rice (Oryza sativa L. subsp. japonica) seed is particularly sensitive to high temperature – and thus climate change – during development and maturation. Cultivar Taipei 309 was grown at 28/208C (12 h/12 h) and then

Delaying Anthesis of Staminate Pistachio with Paclobutrazol [PDF]

open access: yesHortScience, 1993
Anthesis of an important staminate pistachio (Pistacia vera L.) cultivar (B) in Greece was delayed by foliar paclobutrazol (PBZ) sprays applied in June or July the previous season. A September spray was ineffective.

Changes in the nutritional composition of okra fruit and seed during early development

open access: yesAnnals of Tropical Research, 2021
This study investigated the changes in nutrient content of the fruit and seed of Okra or Lady Finger during development and maturation. Okra flowers were tagged at flower opening or anthesis.

ps2, the gene responsible for functional sterility in tomato, due to non-dehiscent anthers, is the result of a mutation in a novel polygalacturonase gene [PDF]

open access: yes, 2009
The recessive mutation ps-2, which appeared spontaneously in tomato, confers functional male sterility due to non-dehiscent anthers. In this study, we isolated and characterized the PS-2 gene.
