Papaya pollen viability and storage
Scientia Horticulturae, 1989Abstract Papaya pollen viability, tube growth and storage were studied. Pollen germination on a drop of modified Brewbaker medium at 22–26°C closely reflected in vivo germination. Two vital stains gave pollen viability estimates that correlated closely with pollen germination percentage.

Hybrid Tea-rose pollen. II. Inheritance of pollen viability
Euphytica, 1977Pollen viability was evaluated in about 500 seedlings originating from 31 crosses between nine commercial Hybrid Tea-rose varieties. The data indicated that pollen viability was inherited additively.

Pollen production and pollen viability in male jojoba plants
Industrial Crops and Products, 2003Jojoba (Simmondsia chinensis (Link) Schneider) is a dioecious wind pollinated shrub native to the Sonora desert of the southwestern USA and Northern Mexico. A comprehensive program for the selection of female cultivars was conducted in Israel for many years. However, selection for male cultivars as pollen sources has largely been neglected. The current

Viability and storage of bromeliad pollen
Euphytica, 2002Several 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, 1994Declining 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, 1993Grain 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, 1958SUMMARY 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, 2012In 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 ...

POLLEN VIABILITY AND GERMINATION RATES OF 45 WATERMELON GENOTYPES
Acta Horticulturae, 2007This study was conducted at the Department of Horticulture, Faculty of Agricultureof Cukurova University in 2002. Eighty three watermelon accessions,collected from different regions and provided by the Turkish genebank (MenemenAgricultural Research Institute), were used for this study. Watermelon plants weregrown in the research greenhouses of Cukurova
