Seed vigor is an important attribute of quality for successful food production ( Rajjou et al., 2012 ). Bell pepper ( Capsicum annuum L.) multiplication is performed by seeds, which are characterized by slow germination and low uniformity of
). Mechanical scarification using a scarifier is a more practical method of scarification than other techniques ( Hicks et al., 1989 ). Vigor tests are more accurate in determining field crop performance of a seed lot than standard germination tests and their
the rate of germinated seeds on the 20th day. Germination index was GI = Σ(Gt/Tt), where Gt is the number of germinated seeds in Day t and Tt is the time corresponding to Gt in days. Vigor index was VI = GI × shoot height on the 25th day. MGT was
found to result in the most promising improvements according to the data displayed in Table 1 . Table 1. Germination percentage of I. indigotica seeds according to different priming treatments under 100 m m NaCl stress. The germination index, vigor
period is very long. Therefore, the M. sprengeri has low seed vigor and long germination time as well as long seedling emergence time under natural environment. Improvement of the seed germination rate and seedling establishment can be helpful to
to reach 50% of final germination percentage (GT 50 ), and seed length vigor index (SLVI) in black cumin after 30 d in culture during Oct. 2018 at the farm of Kafrelsheikh University (Kafr El-Sheikh, Egypt). The impermeability of resistant seeds
conditions are near optimum, the standard germination may predict relative seedling emergence potential of the lot in the field. However, field conditions are often suboptimal. Seed vigor is composed of various features of seed quality and is indicative of
Sealer (Clamco Corp., Cleveland, OH). Nontreated and nonstored caryopses were used as controls. Slant tests were used to determine seed vigor ( Smith et al., 1973 ). One cut germination blotter No. 385 of 75 × 120-mm size was placed into each
categorized as either seeded or parthenocarpic. For the studies evaluated in 2004 and 2005, initial F 1 hybrids were generated from 10 field-grown families, and better performing clones were selected and retained. Selected clones (based primarily on vigor
