The systematic significance of floral morphology, nectaries, and sugar nectar concentration in epiphytic cacti of tribes Hylocereeae and Rhipsalideae (Cactaceae). Nectar volume, sugar concentration and sugar production were measured at daily intervals from bud opening until the fading of flowers. This article is missing information about Miscanthus hybrids (miscanes). One of the fundamental questions in plant biology concerns the nature of the signals that bring about the transition from vegetative to reproductive growth. Sugar production peaked on the second day, coinciding with the male phase. Special type: Ficus, Salvia, Euphorbia.

The first spikelet to flower is generally in the middle third of the spike and usually near the upper part of this section; the flowering progresses rather rapidly upwards, downwards a little slower. floral biology of onion from perspective of pollinator activity. Save to Library. It is a reproductive unit in angiosperms. The rachilla, sterile lemmas and the rudimentary glumes allsupport the floret. Create Alert. These results are excellent compared to natural flowering, but the infrastructure investment (AUD 620 000 per facility, present value) begs the question whether managed flowering can be further optimised. The floral biology and the development of fruits and seeds were also determined. The larger protective glume covering the floret is called thelemma and the smaller one is referred to as the palea. Standard package of practices was followed. The popular onion cultivar Arka Pragathi was used in the study. to their pollination biology and ecology. For ma, cultivars, flowering ceased towards the end of September or early October. Cymose: Cotton, Jasmine, Calotropis. Floral visitors: floral visitors were sampled using an insect net (diameter = 30.5 cm) from April 25 to 29 2003. The present paper reveals the floral biology, breeding system and pollination of Oxystelma esculentum (L.f.) Sm. Flowers were protogynous, and the thick, fleshy petals remained almost closed, thus forming a pollination The perianth is greenish-white and the stamens numerous, producing abundant pollen.
