Cavitation fatigue and its reversal in sunflower (Helianthus annuus L.).
"Cavitation fatigue" is the increased susceptibility of a xylem conduit to cavitation as a result of its prior cavitation. It was investigated whether cavitation fatigue induced in vivo could be repaired in intact plants. Sunflowers (Helianthus annuus L.) were subjected to soil drought in the greenhouse. Native embolism and vulnerability to cavitation was measured in well-watered controls and a...
متن کاملIntraspecific variation in embolism resistance and stem anatomy across four sunflower (Helianthus annuus L.) accessions.
Drought-induced xylem embolism is a key process closely related to plant mortality during extreme drought events. However, this process has been poorly investigated in crop species to date, despite the observed decline of crop productivity under extreme drought conditions. Interspecific variation in hydraulic traits has frequently been reported, but less is known about intraspecific variation i...
متن کاملTOLERANCE OF SUNFLOWER (Helianthus annuus L.) TO IMAZETHAPYR
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activ...
متن کاملCombining ability analysis for seed yield and its components in Sunflower (Helianthus annuus L.)
Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...
متن کاملMetal accumulation by sunflower (Helianthus annuus L.) and the efficacy of its biomass in enzymatic saccharification
Accumulation of metal contaminants in soil as a result of various industrial and anthropogenic activities has reduced soil fertility significantly. Phytoextraction of metal contaminants can improve soil fertility and provide inexpensive feedstock for biorefineries. We investigated the hyperaccumulation capacity of sunflower (Helianthus annuus) biomass by cultivating these plants in various conc...
