The Effect Of Activator Application On The Anatomy, Morphology, And Viability Of Lycopersicon Esculentum Mill. Pollen, İlkay Öztürk Çali, Feyza Candan
Turkish Journal of Biology
The present study examined the effect of ACT-2, a K-vitamin group activator intensively applied to tomato (Lycopersicon esculentum Mill.), on the anatomy, morphology, and viability of tomato pollen from plants grown under greenhouse conditions. The activator was applied to tomatoes at the recommended dosage (150 cc/100 L of tap water) and double the recommended dosage (300 cc/100 L of tap water). Pollen width and length, exine and intine layer thickness, pore width and length, and crevice width and length were measured using an ocular micrometer. Reductions were observed in all the measured parameters in all application groups, except for pollen …

A Study Of Pollen Mitosis And Pollen Morphology Inhexaploid (2n=24) Bellevalia Edirnensisözhatay & Mathew, Feruzan Dane
Turkish Journal of Biology
: The pollen mitosis and pollen morphology of hexaploid (2n=24) Bellevalia edirnensis Özhatay & Mathew were examined. Microspores exhibited variation in size, and the exine and aperture developed before pollen mitosis began. During pollen mitosis, polarization, asymmetric styles and normal divisions were observed together with some abnormalities. During polarization of the microspore both nucleus migration and vacuole formation were common. The generative nucleus was in the proximal pole and the vegetative nucleus was in the distal pole. It was also determined that the mature pollens were 2-celled, the shape of the pollens was sphaeroidea, the type of the pollens was …
