The production of H2O2 in two week-old soybean unifoliate
leaves was examined 12 h after application of EplT4 (10 mg) or H2O (negative control).
Such articulation reflects the unifoliate
condition of the leaves in Berberis.

The treatments were: 1) control (plants with no injury); 2) removal of one cotyledon; 3) removal of both cotyledons; 4) removal of both cotyledons and one unifoliate
leaf; 5) removal of both cotyledons and both unifoliate
leaves; 6) removal of one unifoliate
leaf; 7) removal of both unifoliate
leaves; 8) cut below the unifoliate
leaves; 9) removal of the trifoliate leaf sprouts; 10) total defoliation (including trifoliate leaves); and 11) total defoliation with additional removal of the apical bud.
Emergence and plant density were determined by counting the number of plants in a plot at the V2 stage, when the trifoliate at the node above the unifoliate
was fully developed (Fehr and Caviness, 1977).
15), two first instar nymphs were placed together on the abaxial side of a unifoliate
leaf of four different [V.
A disease survey conducted in Saskatchewan, 2002, indicated that cultivars with fern leaves were less susceptible to Ab than those with unifoliate
leaves (Chongo et al.
(UN37, UN56, UN88, UN113, UN162, UN173, UN179) Vicia faba L.
Surutato-77 is a unifoliate
kabuli type cultivar developed and released in Mexico, and FLIP 85-58 is a Ascochyta blight resistant germplasm line provided by K.
Schnieder (1984) suggested an alternative method of determining FD using mean unifoliate
internode length (UIL) of seedlings is an indirect measure of internode contraction, and strong positive relationships between UIL and FG (Schneider et al.
A 1 to 6 scale was used to measure wilting, where 1 = no wilting symptoms visible, 2 = one leaf with wilting symptoms (the two unifoliate
leaves were rated together as one leaf and the three leaflets of a trifoliate leaf were rated together as one leaf), 3 = two leaves with wilting symptoms, 4 = three or more leaves with wilting symptoms, 5 = petioles collapsing, 6 = main stem (total plant) collapsing.
