An unknown Vincetoxicum species has recently been discovered in eastern Thailand. It is a twiner that resembles its morphology flexuosum s.l., variable taxon widely occurring from tropical Asia to Australia. Morphological examination showed despite similarities growth habit, leaf shape, gross appearance of inflorescence structure and flower colour, these two elements exhibit substantial differe...

Abstract. Fridayanti N, Widajati E, Ilyas S, Budi SW, Palupi ER. 2023. Phenology of flowering and seed development jernang rattan (Daemonorops spp.). Biodiversitas 24: 349-358. Jernang has a high economic value due to its resin content in the exocarp, as raw material dyes, medicines, cosmetics. The is highest immature fruit skin (exocarp); therefore, fruits are harvested before germinable. As c...

due to physiological disorder, primary bud necrosis (pbn) in grapevine is a great problem in vineyards, resulting in reduced yield. primary bud necrosis (pbn) is physiological disorder resulting in the death of the primary bud. the present study conducted through a light on this critical problem in a vineyard of cisakht region. a factorial experiment with three levels of cold temperature (-10, ...

Herbaceous peony (Paeonia lactiflora Pall.) is an important ornamental plant worldwide. In its natural state, P. often manifests traits like rapidly elongating internodal growth, loose types, and soft inflorescence stems. However, very little has been known about the measures for controlling these traits. This study investigated effect of applying paclobutrazol (PBZ) on growth flower quality in...

Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...

The anatomy of leaves and inflorescence axes of Spathanthus (2 spp.), Rapatea (2 spp.), Cephalostemon (1 sp.), and Duckea (1 sp.) (Rapateoideae, Rapateaceae) was studied to identify useful characters for taxonomy. The cross-section shape of inflorescence axis differentiates the genera, while the cross-section shape and structure of leaf midrib has a specific value. The following characteristics...

The aerodynamics of wind pollination selects for an intimate relation between form and function in anemophilous plants. Inflorescence architecture and floral morphology vary extensively within the Poaceae, but the functional implication of this variation remains largely unknown. Here we quantify associations between floret, culm, and inflorescence characteristics for 25 grass species in Kananas...
