Evaluasi Galur Haploid Ganda Pelestari Hasil Kultur Antera untuk Perakitan Galur Mandul Jantan pada Padi [PDF]

, 2009
Hybrid rice has been proven to be the key factor to increase food supply in highly populated countries such as China and India. The success has encouraged the government of Indonesia to intensify research and development on hybrid rice using cytoplasmic ...

Principal component analysis of morpho-floral traits in Oryza sativa × Oryza longistaminata advanced backcross lines of rice [PDF]

Hybrid rice technology substantially improves the food security of South Asian countries where rice (Oryza sativa L.) is a staple food. Several traits contribute to hybrid seed production efficiency, among which stigma exsertion is crucial for enhancing ...

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

The spatial distribution of a hummingbird‐pollinated plant is not strongly influenced by hummingbird abundance

American Journal of Botany, Volume 112, Issue 5, May 2025.
Abstract Premise Many angiosperms have evolved specialized systems that promote pollination by specific taxa. Therefore, plant distributions may be limited by the local abundance of their specialist pollinators. In eastern North America, Lobelia cardinalis is thought to be pollinated solely by Archilochus colubris, the only hummingbird species found in

Pengaruh Aplikasi Asam Giberelin (Ga3) Terhadap Hasil Benih Padi Hibrida [PDF]

, 2014
Hasil benih padi hibrida sistem tiga galur memiliki kelemahan, yaitu rendahnya eksersi malai dan tingkat penyerbukan silang,sehingga hasilnya rendah. Percobaan terdahulu menunjukkan bahwa aplikasi GA3 dapat meningkatkan hasil melalui peningkatan eksersi ...

Handbook of protocols for standardized measurements of floral traits for pollinators in temperate communities

Methods in Ecology and Evolution, Volume 16, Issue 5, Page 988-1001, May 2025.
Abstract Floral traits describe organs or structures directly related to plant reproduction, and they are essential to understanding plant–pollinator interactions, notably for conservation purposes. The growth of plant trait‐based approaches lies in the availability of data shared by the international research community on dedicated platforms, as well ...

Exploiting Genetic and Genomic Resources to Enhance Heat-Tolerance in Tomatoes [PDF]

, 2019
High temperature is one of the most detrimental abiotic stresses in tomatoes. Many studies highlighted that even small increases in temperature can alter the plant reproductive system, causing a significant reduction in tomato yield.

Enhancing entomophilous pollination for sustainable crop production

The Plant Journal, Volume 122, Issue 4, May 2025.
SUMMARY Successful fertilization of insect‐pollinated crops hinges on a delicate interplay of olfactory and visual signals of pollinator attraction, the chemical complexity of nectar and pollen rewards, and the physical interaction between insects and flower anatomy for efficient pollen transfer.

Quantitative assessment of kernel set and risk of out-crossing in maize based on flowering dynamics [PDF]

, 2004
Pollination in maize can occur only if airborne pollen shed by the staminate flowers on the tassel is captured by the stigmas of the pistillate flowers borne on the ear.

Registration of Tx3499–Tx3503 sorghum germplasm resistant to acetyl‐coenzyme A carboxylase‐inhibiting herbicides

Journal of Plant Registrations, Volume 19, Issue 1, January/April 2025.
Abstract The sorghum [Sorghum bicolor (L.) Moench ssp. bicolor] germplasm lines Tx3499–Tx3503 (Reg. no. GP‐948–Reg. no. GP‐952, PI 706257–PI 706261) were developed by the Texas A&M AgriLife Research sorghum breeding program in 2024. These lines are resistant to acetyl‐coenzyme A carboxylase (ACCase)‐inhibiting herbicides used for post‐emergence control
