The radicle emergence test and storage longevity of cucurbit rootstock seed lots
نویسندگان
چکیده
A study was carried out to test whether a single count of radicle emergence (RE test) would correlate with the storage potential seed lots cucurbit ( C. maxima × moschata ) rootstock cultivars. The RE performed by counting percentage between 26 and 100 hours germination. Seed longevity determined at 75% relative humidity 35°C over days, survival curves constructed based on normal germination percentages. K i (estimated initial viability in probits), ? (standard deviation distribution death time) p 50 (time for fall 50%) were through probit analysis. Correlation analysis showed that counts particularly 30 34 highly P < 0.01) correlated percentage, . It can be concluded tests used as an indicator subsequent lot

A role for seed storage proteins in Arabidopsis seed longevity
Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...

Seed germination patterns were studied in E. purpurea (L.) Moench grouped by seed source, one group of seven lots from commercially cultivated populations and a second group of nine lots regenerated from ex situ conserved wild populations. Germination tests were conducted in a growth chamber in light (40 μmol·m(-2)·s(-1)) or darkness at 25 °C for 20 days after soaking the seeds in water for 10 ...
