Hidden Stigmas Enhance Heat Resilience: A Novel Breeding Trait for Sustaining Rice Spikelet Fertility Under Nocturnal Heat Stress [PDF]
AgronomyHeat stress during the flowering stage induces a remarkable decrease in rice spikelet fertility, mainly due to poor pollination manifesting as insufficient pollen deposited on the stigma.

Assessing the Genetic Improvement in Inbred Late Rice against Chilling Stress: Consequences for Spikelet Fertility, Pollen Viability and Anther Characteristics [PDF]
Agronomy, 2022 The development of varieties with strong tolerance is one of the important strategies to diminish the negative impact of chilling stress during heading on the spikelet fertility and yield formation of late-season rice.

High night temperature induces contrasting responses for spikelet fertility, spikelet tissue temperature, flowering characteristics and grain quality in rice [PDF]
Functional Plant Biology, 2014 Climate change is increasing night temperature (NT) more than day temperature (DT) in rice-growing areas. Effects of combinations of NT (24-35°C) from microsporogenesis to anthesis at one or more DT (30 or 35°C) at anthesis on rice spikelet fertility, temperature within spikelets, flowering pattern, grain weight per panicle, amylose content and gel ...

High temperature stress and spikelet fertility in rice (Oryza sativa L.) [PDF]
Journal of Experimental Botany, 2007 In future climates, greater heat tolerance at anthesis will be required in rice. The effect of high temperature at anthesis on spikelet fertility was studied on IR64 (lowland indica) and Azucena (upland japonica) at 29.6 degrees C (control), 33.7 degrees C, and 36.2 degrees C tissue temperatures.

Effects of Low Temperature Stress on Spikelet-Related Parameters during Anthesis in Indica–Japonica Hybrid Rice [PDF]
Frontiers 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.

Effect of high temperature and water stress on pollen germination and spikelet fertility in rice [PDF]
Environmental and Experimental Botany, 2011 In future climates, rice could more frequently be subjected to simultaneous high temperature and water stress during sensitive developmental stages such as flowering. In this study, five rice genotypes were exposed to high temperature, water stress and combined high temperature and water stress during flowering to quantify their response through ...

Pedicellate Spikelet Fertility in Big Bluestem from Eastern South Dakota [PDF]
Journal of Range Management, 1983 Within a nursery of big bluestem (Andropogon gerardii Wt.) from seed collections made in eastern South Dakota, 86% of the plants possessed fertile pedicellate spikelets. From 10 random culms of 462 plants representing 20 different collecetion sites, seed-bearing sessile and pedicellate spikelets were separated and weigbed.

The effect of alternate wetting and drying (AWD) on spikelet fertility, grain traits and the biosynthesis of 2-acetyl-1-pyrroline (2-AP) in rice grown under high temperature [PDF]
BMC Plant BiologyBackground High temperature attributed to climate change is a major obstacle to rice production. This study examined how alternate wetting and drying (AWD) irrigation can mitigate the effects of high temperatures on rice production.

Independent genetic factors control floret number and spikelet number in Triticum turgidum ssp. [PDF]
Frontiers in Plant ScienceWheat grain yield is a complex trait resulting from a trade-off among many distinct components. During wheat evolution, domestication events and then modern breeding have strongly increased the yield potential of wheat plants, by enhancing spike ...
