Hydrological transport and endosperm weakening mechanisms during dormancy release in Tilia henryana seeds.

Seed germination is a pivotal stage in the plant life cycle, with endosperm weakening and radicle elongation serving as crucial prerequisites for successful endospermic seed germination. Tilia henryana seeds exhibit deep dormancy, necessitating a period of 2-3 years to germinate in a natural environment, and the germination rate is extremely low. This study employed morphological and physiological approaches to dynamically analyzing the hydrological mechanism and the endosperm weakening process during the dormancy release of T.

The metagenomics of soil bacteria and fungi and the release of mechanical dormancy in hard seeds.

Persistence in the soil is a function of seed physiology, particularly non-germination and inherent lifespan. However, for seeds with mechanical dormancy, non-germination is also a function of the composition and activity of the soil microbiota. We attempted to screen out microorganisms in the soil that can specifically and rapidly decompose the hard fruit pericarps of Maxim.

Sulfuric Acid and Gibberellic Acid (GA) Treatment Combined with Exposure to Cold Temperature Modulates Seed Proteins during Breaking of Dormancy to Germination in Tilia miqueliana.

Tilia miqueliana produces woody seeds that exhibit deep dormancy. In this study, we used cell biology methods, including Paraffin section determination and Coomassie brilliant blue staining, as well as proteomics-based methods, including two-dimensional electrophoresis with matrix-assisted laser desorption/ionisation tandem time-of-flight mass spectrometry (2DE-MALDI-TOF/TOF), to examine the effects of HSO-GA and cold stratification (3 °C) treatment on proteins during dormancy release and germination in T. miqueliana seeds.
