The effect of pollen storage temperatures on pollen viability, fruit set and fruit quality of six date palm cultivars

Scientia Horticulturae, 2018
Asynchronous maturation of male and female flowers in date palm trees is frequently occurs, making pollen storage operation necessary to ensure pollination.

Viability and storage of bromeliad pollen

Euphytica, 2002
Several bromeliad species from two different subfamilies, were used to develop a reliable method to evaluate pollen viability. Pollen germination on a medium containing 20% sucrose, 0.001%H3BO3 and 0.5% agar was comparable to germination on a compatible stigma. Maximum germination was reached within 2 to 10 hours depending on the species. Based on this

Declining viability and lipid degradation during pollen storage

Sexual Plant Reproduction, 1994
Declining viability of pollen during storage at 24° C in atmospheres of 40% relative humidity (RH) and 75% RH was studied, with special emphasis on lipid changes. Pollens of Papaver rhoeas and Narcissus poeticus, characterized by a high linolenic acid content, were compared with Typha latifolia pollen which has a low linolenic acid content.

Effects of Boron on Pollen Viability in Wheat

Plant and Soil, 1993
Grain set failure in wheat, caused by boron (B) deficiency, is associated with poorly developed pollen and anthers. This paper presents results of a study of the effect of B on pollen viability when it was supplied “internally” through the roots and externally in an agar medium for in vitro germination.

A SIMPLE POLLEN VIABILITY TEST

Australian Forestry, 1958
SUMMARY A simple method of determining the germination of pine pollen is described. It consists of Ousting the pollen to be tested on a slide which is placed over water in a petri dish, which is kept at about 25°C for 72 hr. The use of cotton blue stain applied 'at the time of examination assists counting the germinated grains, especially when they are

Air quality biomonitoring through pollen viability of Fabaceae

Environmental Monitoring and Assessment, 2012
In this study, pollen viability and germination of three plant species, Cercis siliquastrum L., Robinia pseudoacacia L., and Spartium junceum L., belonging to the Fabaceae family, was evaluated in sites with different intensity of road traffic, constantly monitored with continuous analysers for air pollutants (carbon monoxide (CO), sulphur dioxide (SO ...
