The APase activity was influenced by SA concentrations and was significant (p 0.001) in both years (Table 2 and Fig.
The effect of SA concentrations was significant (p>0.001) in terms of APase activity at all three phenological stages in both seasons (Table 2 and Fig.
Table 1: Mean squares from the analyses of variance and coefficient of variation (C.V.) of activities of APase (umol p!nitrophenol released min-1 mg-1 protein) in pea (Pisum sativum L.) varieties treated with SA by different modes of application at phenological growth stage BBCH 73 (30% of pods have reached average maximum length), BBCH 77 (70% of pods have reached average maximum length), BBCH 83 (30% of pods ripe, dry and hard) and BBCH 88 (80% of pods ripe, dry and hard) during year 2003-2004 and 2004-2005
Table 2: Mean squares from the analyses of variance and coefficient of variation (C.V.) of the activities of APase in pea (Pisum sativum L.) varieties treated with SA concentrations by different modes of application during year 2003-2004 and 2004-2005 at phenological growth stage BBCH 01 (beginning of seed imbibition), BBCH 03 (seed imbibition complete) and BBCH 05 (radicle emerged from seed)
There was a significant difference between modes of application of SA in terms of APase activity (p > 0.001) at all three phenological stages during year 2003-2004 and 2004-2005 (Table 2 and Fig.
Different developmental processes that cause APase induction include flowering and senescence (De Leo and Sacher, 1970; Lal and Jaiswal, 1988), fruit ripening (Kanellis et al., 1989) and seed germination (Gibson and Ullah, 1988).
Although [R.sup.2] is reasonably high for several of the responses (0.7 for APase, 0.9 for cells, 0.7 for protein), [Q.sup.2] is low (0.35, 0.3, and 0.35, respectively).
APase activity was monitored as the formation of para-nitrophenol (p-NP) from the substrate para-nitrophenyl phosphate (p-NPP).
The rate of p-NP formation by APase in crude extracts prepared from roots of R.
Inhibition of APase activity was measured at saturating substrate concentration (15 mM) in the presence of increasing TA concentration.
The effects on TA levels and APase activity of added PVP were measured.
Many authors have noted that plants starved for phosphorus typically exhibit elevated APase activity (Ascencio 1997; Dinkelaker and Marschner 1992).
