Seed Vigor and the Uniformity of Emergence of Corn Seedlings

Crop Science, 2012
ABSTRACTSeed vigor is defined as those “seed properties that determine the potential for rapid, uniform emergence and development of seedlings under a wide range of field conditions.” Seedlings from high‐vigor seed lots are expected to emerge more uniformly than those from low‐vigor lots.

Improving the seedling vigor and seedling performance of glutinous corn by hydropriming

Ecology, Environment and Conservation
A study on hydropriming with different durations (4, 8, and 12 h) tested the seedling vigor of glutinous corn. Ambient conditions (temperature: 30 ± 2 ˆC; relative humidity - 65 ± 5%) were used as the growing conditions for the hydro primed and unprimed seeds (control).

Genetic Variation for Seedling Vigor Traits in Rice

Crop Science, 1996
Seedling vigor is important for stand establishmet in direct‐seeded rice (Oryza sativa L.) culture. Genetic variation for, heritability of, and relationships among seedling vigor traits in 27 diverse rice cultivars and two segregating populations from crosses between low‐ and high‐vigor cultivars were studied.

Seedling Rate of Development Index: Indicator of Vigor and Seedling Growth Response

Crop Science, 1990
Seedling growth analysis has been shown to be a useful tool to supplement the results of the standard viability test when evaluating seed lots for vigor. A number of indices have been proposed to describe the vigor of a particular seed lot. Few of these indices have been rigorously tested for their response to varying hypothetical emergence ...

Recurrent Selection for Seedling Vigor in Kura Clover

Crop Science, 2001
Kura clover (Trifolium ambiguum M. Bieb.) is a rhizomatous perennial forage legume that has outstanding persistence once established. Low seedling vigor presents a challenge to kura clover establishment. Kura clover seedlings partition a significant portion of their dry matter to below ground growth.

SEED SIZE AND SEEDLING VIGOR IN BIRDSFOOT TREFOIL

Canadian Journal of Plant Science, 1967
The relationship between seed size and seedling vigor in the field and greenhouse was determined for European-type birdsroot trefoil (Lotus corniculatus L).Sixty-four open-pollination progeny lines drawn from a nursery of 2,000 plants were grouped, on the basis of seed size, into eight classes each having eight lines.

Role of Growing Media on Seedling Vigor of Tomato

Environment and Ecology
Robust seedlings are the most important inputs for getting a good crop with high yield and quality. Tomato seedlings raised in plugtrays are considered better than those raised in conventional nursery, but the media on which they are raised determine the seedling vigor and quality.

SEEDLING VIGOR STUDIES IN MORSHANSK BIRDSFOOT TREFOIL

Canadian Journal of Plant Science, 1969
Progenies of 60 birdsfoot trefoil plants out of the Russian strain Morshansk which differed in maturity, seed load, and seed size were evaluated for speed of germination, seedling vigor, and rate of tillering.The results indicated that, first, seed load is unlikely to affect greatly the seed size and seedling vigor of the progeny; secondly, late ...

SELECTION METHODS FOR SEEDLING VIGOR IN BIRDSFOOT TREFOIL

Canadian Journal of Plant Science, 1971
In 1969, 72 large-seeded lines derived through open pollination were used to establish a seedling vigor test upon which three selection schemes were imposed. First, the best 16 lines were identified and their maternal parents intercrossed to form a selection-by-genotype group.

SEED SIZE, GERMINATION RESISTANCE AND SEEDLING VIGOR IN BARLEY

Canadian Journal of Plant Science, 1971
Marked differences in seedling vigor, as measured by dry weight two weeks after germination, have been demonstrated in F3 lines of a barley (Hordeum vulgare L. emend Lam.) cross between CI 5791 and Ming (CI 4797). These differences can be largely accounted for by differences in seed size, which is itself related to segregation for head type, and by ...
