In vitro pollen germination and pollen viability study in brinjal [PDF]

, 2022
Abstract For hybrid seed production, it is prerequisite to know the floral biology of the crop and pollen biology is an integral part of flower biology of any crop to understand artificial hybridization more efficiently. After pollination, germination of the viable pollen is important for proper fertilization of ovary and to develop optimum ...

Higher Temperature at Lower Elevation Sites Fails to Promote Acclimation or Adaptation to Heat Stress During Pollen Germination

Frontiers in Plant Science, 2018
High temperatures associated with climate change are expected to be detrimental for aspects of plant reproduction, such as pollen viability. We hypothesized that (1) higher peak temperatures predicted with climate change would have a minimal effect on ...

The estimation of pollen viability of snowdrop (Galanthus nivalis L.)

International Journal of Horticultural Science, 2000
In the present experiment pollen viability of snowdrop were tested using four vital dyes (TTC, Baker' procedure, MTT and FDA) to determine their potential to differentiate fresh living pollen from pollen heated for 12 hours at 80 °C (killed pollen).

Metabolomic and transcriptomic analyses reveal that sucrose synthase regulates maize pollen viability under heat and drought stress

Ecotoxicology and Environmental Safety, 2022
Maize pollen is highly sensitive to heat and drought, but few studies have investigated the combined effects of heat and drought on pollen viability. In this study, pollen's structural and physiological characteristics were determined after heat, drought,

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications

Advanced Robotics Research, EarlyView.
A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward

Screening for male fertility status in selected banana genotypes

Electronic Journal of Plant Breeding, 2019
In the present study, twenty-five banana cultivars (eight diploids and seventeen triploids) were screened for their male fertility status with reference to the pollen output per anther, pollen size and pollen viability.
