“…The presence of four zones was detected in the in vivo growing pollen tubes of Mimulus aurantiacus as reported by Cresti et al (1977), Ciampolini et al (1982) in their in vitro and by Cresti et al (1979Cresti et al ( , 1980, Uwate and Lin's (1980) in vivo studies. In general, the constitution of organelles in various zones in vitro and in vivo are quite similar as also seen in Lycopersicum (Cresti et al 1977), (Cresti et al 1980), in Malus (Speranza et al 1982, in Prunus avium (Cresti et al 1979), in cherry , and in Conospermum (Stone et al 2004).…”

“…Apical and subapical zones are active zones because they are rich of organelles such as: mitochondria, well-developed dictyosomes and lipid bodies. We also observed areas which would be designated as smooth and rough endoplasmic reticulum zones (Uwate and Lin 1980). Our micrographs showed small vesicles arising from the well-developed dictyosome cisternae.…”

“…Besides playing a major role in the carbohydrate metabolism, dictyosomes have functioned as sorting and dispatching station for the ER products (Dupree and Sherrier 1998). According to Uwate and Lin (1980), these vesicles have been arisen from smooth endoplasmic reticulum cisternae, and rough endoplasmic reticulum circumscription of vacuoles. Lipid bodies were visible in various zones in our study.…”

“…Initial studies have been done in Petunia (Solanaceae) (Sassen 1964), (Cresti and Van Went 1976) and Lilium longiflorum (Liliaceae) (Rosen et al 1964). Few reports have appeared in 1980s, concerning the fine structure of the pollen tubes in Lycopersicum peruvianum (Solanaceae) (Cresti et al 1977), (Cresti et al 1980), Prunus avium (Rosaceae) (Cresti et al 1979), (Uwate and Lin 1980), Prunus sp. (Rosaceae) , Nicotiana alata (Solanaceae) (Lancelle et al 1987).…”

“…Those studies were generally on the ultrastructure of in vitro pollen tubes except the studies with Prunus avium (Cresti et al 1979), (Uwate and Lin 1980). It is too hard to perform and to follow the development of in vivo pollen tubes, so these studies are very important and restricted.…”

The aim of this study is to give information on ultrastructure of in vivo pollen tubes of Mimulus aurantiacus which were collected from the Botanical Garden of the University of California at Berkeley. Materials were prepared according to electron microscopy methods and examined under Zeiss electron microscope. Four zones were examined in the pollen tubes of Mimulus aurantiacus. Apical zone: Mitochondria, smooth endoplasmic reticulum, rough endoplasmic reticulum, dictyosomes and secretory vesicles were observed. Subapical zone: This area contained abundant rough endoplasmic reticulum and occasionally some smooth endoplasmic reticulum. The polysomes, mitochondria, proplastids that contain starch, small vacuoles and a few lipid bodies were detected. Nuclear zone: Both generative and vegetative cell nuclei lie in this zone. The vegetative cell nucleus was large and long. Rough endoplasmic reticulum, mitochondria, ribosomes, dictyosomes, and amyloplasts that are rich of starch were observed. Vacuolation and plug formation zone: Cytoplasm of the tubes was full of large vacuoles. Few organelles such as mitochondria, dictyosome and rough endoplasmic reticulum were detected along their periphery.

Both internal anatomy andexternal morphology ofthe mature pollen grain of Nicotiana alata have been studied, together with pollen activation and tube emergence and its cytological zonation.A peculiar feature of mature pollen is the occurrence in the vegetative cell cytoplasm of a large quantity ofstacked cisterns of rough endoplasmic reticulum, which thendissociate during pollen activation.Pollen tubeemergence generally occurs 2hr 30minafterhydration, while cytological zonation is complete 4 hr 30 min after hydration when the first callosic plug is formed.
