“…Assessing pollen germination of native Myrtaceae from southern Brazil, Franzon et al (2005) and Franzon and Raseira (2006) observed a similar germination rate to that of kiwi, with 60 to 80 % of germinated pollen grains in culture medium containing boric acid and 10 % sucrose. Similar results were reported for germination of peach pollen (Einhardt et al 2006).…”

“…The method of assessing the viability of pollen through germination in culture medium in vitro is practical and accurate (Einhardt et al 2006). In vitro germination tests were performed for different fruit species, such as Annonaceae (Rosell et al 1999, Bettiol Neto et al 2009), citrus (Pio et al 2007, Ramos et al 2008, apple (Nunes et al 2001, Dantas et al 2005, passion fruit (Cruz et al 2008) and native Myrtaceae (Franzon et al 2005, Franzon and. However, few studies have been published on in vitro viability and storage conditions of pollen grains of kiwi (Abreu and Oliveira 2004).…”

-Kiwi is a dioecious plant species, requiring cross pollination for fruit production. The objective of this study was to evaluate the in vitro viability and shelf life of pollen grains of two kiwi varieties. Flowers of the cultivars Matua and Tomuri were collected and the pollen germinated in vitro, in culture medium containing agar (1 %), sucrose (0, 5, 10, 20 and 40 %) and boric acid (0 and 50 mg L -1 H 3 BO 3 ). Pollen grains were stored in a BOD incubator (25.0 °C), refrigerator (4.0 °C), freezer (-18.0 °C) and in liquid N 2 (-196.0 °C), and evaluated after 0, 40, 120, 240 and 365

“…Consequently, the germination percentages and tube lengths of genotypes decreased along long storage period. It was found in such investigation that the feijoa pollen partially lost its viability after been stored for 90 days in a freezer and had a great loss after 150 days [28]. In present work, Germination percentages and tube lengths of MH10, MH26, MH30, MH31, MH34, MH41, MH43, MH46, MH48, MH55, MH57, MH58, MH60, MH61, MH66 and MH69 genotypes significantly decreased from sixth month to twelfth month, some of them completely lost their viabilities.…”

We examined the influence of storage time on germinability and tube growth of freeze stored pollens collected from 25 wild male plants in Actinidia eriantha variety. Pollens were stored in freezer at −20˚C for six months and one year periods to determine changing at germinability in time. In vitro germination was conducted in certain cultural medium defined for Actinidia genus. The results showed that the germination percentages and tube lengths of genotypes decreased at the end of storage period. MH22, MH45, MH47, MH56, MH67, MH70, MH71, MH72, MH74, MH55 and MH61 genotypes were evaluated as vigor genotypes, because they maintained their viability and germination capability displaying statistically insignificant decreasing although their tube lengths significantly decreased except MH67. This investigation provided to determine some robust wild male germplasm resources in A. eriantha in point of durability of pollens against long term conservation for using at future pollination and breeding programs.

“…Kakani et al (2005) claimed that the differences observed in the germination in vitro and pollen tube growth of 12 cotton cultivars (Gossypium hirsutum) were a reflex of the variability in the cultivars. Similarly, Frazon et al (2005) stated that there are differences between species and between cultivars within the species in terms of the conditions required of a medium for in vitro pollen germination. The variation in the growth rate of the pollen tube in angiosperms is extremely high (Baker and Baker 1979).…”
