Improving seed vigor in response to cold stress is an important breeding objective in maize that allows early sowing. Using two cold tolerant inbred lines 220 and P9-10 and two susceptible lines Y1518 and PH4CV, three connected F2:3 populations were generated for detecting quantitative trait locus (QTL) related to seed low-temperature germination ability. At 10°C, two germination traits (emerge...

the present research was conducted under laboratory and field condition to determine seed priming effects on maize inbred line's germination, emergence, and grain yield. seeds of two maize inbred lines include of mo17 (as paternal line) and b73 (as maternal line with cytoplasmic sterility) in the laboratory conditions were subjected to hydropriming for 12, 24, 36 and 48 h, or osmoticprimin...

Abstract This study aimed to evaluate the effect of fruit maturation stages and pre-germination treatments with plant regulators on physiological quality seeds cv. BRS Mel do Cerrado. Two experiments were carried out, germination emergence, installed in a completely randomized design 3 x 2 factorial arrangement, three (1-partially ripe fruits; 2-fully fruits 3-senescent fruits) two (1. [GA4+7 +...

in order to evaluate the effect of freezing stress on electrolyte leakage of three mooseers’ (allium altissimum regel.) ecotypes (shirvan, kalat and tandoureh), a factorial experiment based on completely randomized design with three replications was carried out under the controlled conditions in the faculty of agricultural, ferdowsi university of mashhad, iran, during 2009. plants were grown in...

Feather lovegrass [Eragrostis tenella (L.) Beauv. Ex Roemer & J.A. Schultes] is a C4 grass weed that has the ability to grow in both lowland and upland conditions. Experiments were conducted in the laboratory and screenhouse to evaluate the effect of environmental factors on germination, emergence, and growth of this weed species. Germination in the light/dark regime was higher at alternating d...
