![]() At the same time they show a high stomatal conductance leading to unrestricted rates of transpiration and a lack of capacity to optimize water use efficiency ( WUE). bryopteris plants show a very poor mechanism for its stomatal regulation in response to high light, high temperature, high VPD, high CO 2 and to ABA treatment. With SigmaPlot, you can produce high-quality graphs without spending hours in front of a computer. SigmaPlot graphing software from SYSTAT takes you beyond simple spreadsheets to help you show off your work clearly and precisely. The stomatal sensitivity in response to vapor pressure deficit ( VPD), was maximum at 25 ☌ temperature while at temperatures from 30 to 35 ☌ it was low. SigmaPlot software helps you quickly create exact graphs. bryopteris displayed broad temperature optima for net photosynthesis from 28 ☌ to 37 ☌. This suggests that there was a complete recovery of PSII efficiency during the late evening hours. The effective quantum yield of PSII (Δ F/ F m′) showed an inverse relationship with light and recovered to its maximum at sunset. The diurnal gas-exchange studies under natural conditions showed a bell shaped net photosynthesis curve. These plants have small sized stomata that occur in higher density than in other fern species. ![]() Selaginella bryopteris is a spike-moss lycophyte species with resurrection capability. ![]()
