Effects of storage temperature and duration on pollen grain viability and pollen-tube elongation in Chinese chinqapin (Castanea henryi Skan)

Effects of humidity and temperature on pollen viability of shahani dates

Gibberellin regulates pollen viability and pollen tube growth in rice.

Gibberellins (GAs) play many biological roles in higher plants. We collected and performed genetic analysis on rice (Oryza sativa) GA-related mutants, including GA-deficient and GA-insensitive mutants. Genetic analysis of the mutants revealed that rice GA-deficient mutations are not transmitted as Mendelian traits to the next generation following self-pollination of F1 heterozygous plants, alth...

Pollen and Pollen Tube Proteomics

Germinated pollen grains form pollen tubes that accomplish rapid polarized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more comprehensive understanding of proteins involved in pollen development, germi...

The effect of temperature on pollen germination, pollen tube growth, and stigmatic receptivity in peach.

Temperature is a major climatic factor that limits geographical distribution of plant species, and the reproductive phase has proven to be one of the most temperature-vulnerable stages. Here, we have used peach to evaluate the effect of temperature on some processes of the progamic phase, from pollination to the arrival of pollen tubes in the ovary. Within the range of temperatures studied, 20 ...

effects of temperature and storage time on different varieties of date pollen

pollen storage could facilitate the date palm hand pollination through saving time and space. the main concern is maintaining pollen viability, which is greatly cultivar dependent and is influenced by storage condition. in this study, to address this issue, the effects of cultivar, storage temperature, and time on pollen germination were investigated. a factorial experiment was laid out in a co...
