To determine the time elapsed between the appearance of the floral bud until anthesis, 30 floral buds among 12 plants were randomly selected and identified with colored ribbons, with size of approximately 0.5 cm in length of growing branches.
In this sense, the objective of this study was to study the flora biology aspects of passion fruit cultivars in Tangard da Serra region, Mato Grosso State, Brazi at different evaluation times, based on the following hypotheses: 1) the sugar volume and concentration in the nectar vary among cultivars and evaluation schedules; 2) pollen viability decreases throughout the anthesis and 3) there is synchrony between stigmatic receptivity and pollen viability for the cultivars analyzed.
The SP and F treatments had also earlier spike emergence and anthesis stage.
Marked plants were observed to identify the dates in which 50% of the plants were in anthesis (R4) and physiological maturity (R9) (Counce et al., 2000).
According to the authors, pollen viability decreased from 6 hours after anthesis, and only a very small percentage of pollen germinated after 1 to 3 days.
In 2012-2013 and 2013-2014 seasons, the green leaf area was measured by passing the leaves through a LI-3100 leaf area meter (LiCor, Lincoln, NE, USA) at 7-day intervals after peak anthesis. The gas exchange analysis was conducted in the LPD and HPD populations of two varieties using a Portable Photosynthesis System (LI-6400; LiCor) on the leaves from 09:00 to 11:00.
In all four crosses dominance gene action was found to be important in the inheritance of both days to anthesis and silking.
The experiment was carried out in split plot design with two treatments (non-stress and stress at anthesis) in four replications.
It was all too fierce for my wannabe-Parisienne palette, the anthesis of less is more, it's more 'Kylie on tour' than nonchalant French style.
