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 ...

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 ...

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,

Pollen Viability of Selected Diploid Watermelon Pollenizer Cultivars [PDF]

HortScience, 2008
In the Spring and Fall 2006, the pollen viability of four diploid watermelon pollenizers was evaluated in Quincy, FL. Triploid watermelon plants [ Citrullus lanatus (Thunb.) Matsum. & Nakai.] do not produce sufficient viable pollen to pollenize themselves and a diploid cultivar must be ...
