Phylogenetic trends in TZ staining analysis of six deep dormancy seeds.
The assessment of seed quality and physiological potential is essential in seed production and crop breeding. In the process of rapid detection of seed viability using tetrazolium (TZ) staining, it is necessary to spend a lot of labour and material resources to explore the pretreatment and staining methods of hard...Peng, Chen Yin ; Wu, Yu ; Huang, Wen Hui ; Deng, Zhi Yun ; Sun, Xiao Rui …

New species and a revision of the genus Peperomia (Piperaceae) in Thailand.
We update the descriptions of seventeen native species of Peperomia in Thailand, including a new species, P. ranongensis, and a detailed morphological description for the uncommon species P. kotana based on Thai specimens. We provide a generic description, a key to all the species and provide lectotypifications for P. bavina,... -

Pollen morphology of the Sapotaceae from Thailand and its taxonomic implications.
The external pollen morphology of the family Sapotaceae in Thailand was examined using the acetolysis method to determine its taxonomic significance. Pollen of 39 specimens belonging to 32 species was investigated by means of light and scanning electron microscopy. Pollen grains are found to be monads, isopolar, colporate, lalongate, and...Kunasit, Pongsakorn ; Chantaranothai, Pranom
