Polyploidy and polyembryony in Anemopaegma (Bignonieae, Bignoniaceae)
, 2015 Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Polyploidy is a key process in plant evolution, with the asexual formation of embryos representing a way through which polyploids can escape sterility. The association between polyploidy

DOUBLE HAPLOIDS FROM TWO-EMBRYONIC SEEDS OF PEPPER (Capsicum annuum L.)F1 HYBRID
Acta Scientiarum Polonorum: Hortorum Cultus, 2021 The results of the investigation proved the gametophytic origin of diploids derived from two-embryonic seeds of pepper C. annuum L. hybrid. During the germination of seeds harvested from the red fruited hybrid (C. annuum L. ATZ × C. annuum L.`Sono`) F1,

Polyembryony in citrus: does the largest embryo in the seed develop a nucellar seedling?
Scientia Agricola, 2021 : A generalized concept in the Citrus genus is that highly polyembryonic varieties produce only a small number of hybrids. Small zygotic embryos congregate primarily near the micropyle, while nucellar embryos organize near or away from the micropyle.

Polyembryony ability of jackfruit (Artocarpus heterophyllus) seed [PDF]
, 2013 Polyembryony is common in jackfruit but which part of the seed responded to polyembryony is the main issue. The development of multiple embryos within the same seed is defined as polyembryony.

, 2023 Polyembryony is a type of sporophytic apomixis common in citrus species. Previous studies discovered that embryo traits relate to their sexual or asexual origin. Smaller embryos at the micropyle end are considered zygotic embryos, whereas larger embryos are nucellar.

The evolution of reproduction in Ediacaran–Cambrian metazoans
Biological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Closed Loop Phosphorus Recovery and Recycling for Sustainable Hydroponic Farming
Journal of Sustainable Agriculture and Environment, Volume 4, Issue 3, September 2025.The proposed closed loop recovery and recycling method achieves a 40% reduction in commercial fertiliser use with recycled nutrients, which can be integrated seamlessly within the existing hydroponic systems with minimal capital investment. Stable EC/pH levels enhance nutrient stability and operational efficiency, and achieve 33% fertiliser cost saving.

Environmental effects on chemical composition and physical properties of polyembryonic maize grain
TIP Revista Especializada en Ciencias Químico-Biológicas, 2020 Polyembryony has been reported in maize (Zea mays L.) since the 20th century. This trait is defined as the appearance of two or more seedlings from a germinated seed and has been associated with improvements in the nutritional content of the grain. Maize
