-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
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
