Studies on the Tillering Primordium and Tillering Bud in Rice seedlings : (7) Developmental process of the tillering primordium and tillering bud

open access: yesJapanese Journal of Crop Science, 1958
1) This investigation was undertaken to determine the developmental process of the tillering primordium and tillering bud in rice seedlings. 2) Rice seedlings used in this study were nursed in sand culture from the sowing to the stages of the third foliage leaf, and after then in water culture. Harvested samples were fiked in mixtured fluid of Formalin,

Regulation of tillering in sorghum : genotypic effects

open access: yes, 2010
Background and Aims Genotypic variation in tillering can be caused by differences in the carbon supply-demand balance within a plant. The aim of this study was to understand and quantify the effects of genotype on tillering as a consequence of the ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

AN EVALUATION OF COMMON SPRING WHEAT GERMPLASM FOR TILLERING

open access: yes, 1988
A diverse collection of spring wheat (Triticum aestivum L.) germplasm was evaluated for tillering capacity, spikes m−2, and tiller mortality under both space-planted and solid-seeded conditions.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
