reproductive organ of angiosperms. The development of anthers, the parts of the stamen where pollen is produced, is a delicate and complex process that includes the formation of the anther wall tissue (with a protective function) and pollen (with a reproductive

by the S locus, which contains the genes that control the pollen and pistil specificities. The pistil determinant of the three families is S-RNase , which encodes a basic glycoprotein with ribonuclease activity that is present in the extracellular

Self-incompatibility is a genetic mechanism that exists in flowering plants to prevent a plant from being pollinated by its own pollen and to promote cross-pollination. Gametophytic SI (GSI), one form of SI, has been extensively studied and S

for use in the production of industrial hemp fiber and grain. Male and monoecious plants are problematic for CBD production because of their pollen, which is produced in copious quantities because hemp is a wind-pollinated species ( Small and Naraine

tolerated by ornamental pepper plants as they mature ( Stummel and Bosland, 2007 ). Yellowing and leaf drop are caused by low temperatures and light and insufficient moisture or nutrients ( Stummel and Bosland, 2007 ). In addition, pollen vitality and fruit

deleterious mutations. Reliable protocols for haploid induction based on in situ parthenogenetic haploid induction by irradiated pollen have been published for some species of Cucurbitaceae. Obtaining haploids by in vitro rescue of parthenogenetic melon

studies regarding pollen amount and pollen germination from China ( Guo and Shan, 2010 ; Han et al., 2008 ; Liu and Peng, 1992 ), but no such studies in the United States. Phenology provides basic information about a fruit species introduction and is

an economically viable crop requires improvement of many traits, such as rubber yield and plant vigor. Male sterility is characterized by a lack of functional pollen and has been identified in over 600 species including many agriculturally important

‘Eta’ and ‘Theta’ are two new hazelnut ( Corylus avellana L.) pollenizer cultivars. They were released by the Oregon Agricultural Experiment Station in Jan. 2009 as pollenizers for the late-flowering ‘Jefferson’. They have a very high level of
