“…In field corn, the relation between seed size and emergence, growth and yield has been extensively studied. There was a significant positive correlation between seed size (as indicated by 1000-seed weight) and plant vigor parameters under low temperature (Gubbels 1974). Seed size effect on field corn performance has shown a tendency for small seed classes to produce smaller plants than those from large size classes (Hicks et al 1976).…”

Enhanced Sweet Corn Propagation: Studies on Transplanting Feasibility and Seed PrimingSweet corn hybrids with high-sugar genotypes (sh2) has inherent problem of low seed emergence and stand in the field. This study was conducted to determine the effect of seed size, tray cell size and growing media components on sweet corn transplant transplanting. Other objectives were to evaluate the effect of priming sweet corn seeds on germination in the field. Bio-priming withTrichodermaandBacillus, osmopriming with KNO3, and hydro-priming with H2O have been tested. The results indicated that transplanting sweet corn is feasible with high quality transplants from seeds that germinate well in disease-free environment. Large sweet corn seeds, large tray cells, and vermiculite-based growing media proved to gave higher germination percentages. While same factors did not show pronounced effect on seedling performance in terms of root and shoot length and fresh weight. In the priming experiment, the bio-priming treatment showed the highest germination of seeds percentage among other priming treatments and the control. Sweet corn seeds treated withBacillus megateriumgerminated 50% higher than seeds treated withTrichodermaspp. as bio-control agents.Aspergillus niger, andPenicilliumrepresented 65% of pathogens responsible for failure of sweet corn seed germination. The results of this study demonstrated the feasibility of enhanced sweet corn seed propagation through transplanting and seed priming to improve emergence and field stand.

“…Many studies have shown the existence of genetic variability for germination of maize at low temperatures (P1NNELL, 1949;POLLMER, 1969;GROGAN, 1970;PESEV, 1970;MOCK & EBERHART, 1972 ;GUBBELS, 1974). Most early studies emphasized reliability of germination in the presence of seed-rotting microorganisms, however, the development o feffective fungicidal seed treatments has reduced the need for genetic resistance to these microorganisms (POLLMER, 1969;MOCK & EBERHART, 1972).…”

“…In a subsequent experiment using a selection index which included these two characters, plus seedling growth characters, a positive response to selection was obtained for percentage emergence, but not emergence rate (Mock & BAKR1, 1976). GUBBELS (1974), working with a small number of cultivars, found that time to emergence was significantly correlated with weight and oil concentration of the seed. He suggested that a large seed with a high linoleic acid concentration might be a feature of genotypes with superior ability to emerge under cool conditions.…”

INDEX WORDSZea mays L., maize, genetic variation, low temperature emergence. SUMMARY Full-sib, paternal half-sib and S1 families were derived from a population of maize, Pool 5, with a wide germplasm base. These families were used to study genetic variation for germination percentage, emergence percentage and time to emergence at 10 'C.Genotypic variances were large for all characters, and the best families from the population were markedly superior to hybrids used as checks. Maternal effects appeared to be of overwhelming importance for germination percentage, but variances due to males were significant for emergence percentage and time to emergence. Inbreeding depression at the seedling level was also important for these two emergence characters. Germination and emergence characters were not correlated with seed weight.We concluded that Pool 5 should be a valuable source of genes for improving germination and emergence of maize at low temperatures.

“…Differences in seedling height can be attributed to genetics, as many studies have shown genetic variability for germination of maize at low temperatures (Pinnell 1949, Pollmer 1969, Grogan 1970, Pesev 1970, Gubbels 1974. Stamina positively influenced seedling height across all lots at Point A; however there was a seed lot by treatment interaction (Figure 2).…”
