Identification of IPT9 in Brachiaria brizantha (syn. Urochloa brizantha) and expression analyses during ovule development in sexual and apomictic plants [PDF]

Molecular Biology Reports, 2023
Abstract Background In Brachiaria sexual reproduction, during ovule development, a nucellar cell differentiates into a megaspore mother cell (MMC) that, through meiosis and mitosis, gives rise to a reduced embryo sac. In aposporic apomictic Brachiaria, next to the MMC, other nucellar cells differentiate into aposporic ...

How does the condition of the pasture in late winter influence the plant and animal responses in the subsequent seasons?

Bioscience Journal, 2022
This study aimed to test the hypotheses: (i) the deferred pasture with lower height in late winter has greater herbage accumulation rate (HAR) and better structure, which facilitates the animal selective grazing during the subsequent spring and summer ...

Number and morphology of tiller age groups during summer in Marandu palisadegrass pastures previously used under deferred grazing

Bioscience Journal, 2020
The relative contribution of young, mature and old tillers in the canopy influences the production and structure of the pasture. The objective with this work was to evaluate the balance between tiller appearance and tiller death (BAL) during spring and ...

Does amount of cut vegetal residue on the canopy influence growth and the structural characteristics of marandu palisadegrass?

Bioscience Journal, 2022
The pasture mowing in late winter removes the old forage, improving the pasture structure in spring and summer. However, the residue after mowing can affect tillering, thus limiting forage production and the structural characteristics of pasture.
