“…These results showed that seed moisture content generally declined with increasing age and that, when seeds were subjected to the more rapid drying conditions of the glasshouse, with increasing age of seed at harvest the percentage viability increased and the percentage mortality shown by viable seeds in soil decreased. Similar observations have been made on maize by Rush & Neal (1951). More recently, Oelke, Ball, Wick & Miller (1969) found that the germination percentage of rice increased and predisposition of grain to fungal mould decreased as grain moisture at harvest declined; that is, :as seeds were harvested later.…”

A series of harvests from field plots of peas showed that the younger seeds were at the time of harvest the lower was their percentage viability and the greater their percentage mortality in soil. Young seed also showed a high degree of solute leaching into steep water and had a high moisture content at harvest cornpared with older seeds. Heavy rainfall just prior to harvesting reduced the percentage viability of the dried seed and increased the moisture content of the seed at harvest as well as the leaching of solutes from the dried seed into steep water. Comparisons of moisture content at harvest and seed condition after drying suggested that cotyledons and embryo axes were only able to withstand enhanced drying after removal from the plant if the seed moisture content had already begun to decline whilst the seed was still on the plant.

O presente trabalho teve como objetivo básico estudar comparativamente quatro métodos para a condução do teste de frio, visando a avaliação do potencial fisiológico das sementes de milho. Para tanto, foram utilizados dois cultivares de milho (AG 3010 e AG 5011), cada um representado por 5 lotes com potenciais fisiológicos distintos. Amostras de sementes de todos os lotes foram submetidas a quatro procedimentos do teste de frio, a saber: "terra" (mistura de terra e areia) em caixas empilhadas (método tradicional); "terra" em caixas dispostas lado a lado; bandeja com "terra"; bandeja com "terra" + papel toalha. Estes procedimentos foram comparados com os testes de germinação padrão, envelhecimento acelerado e emergência das plântulas em campo. O teste de frio em bandeja oferece maior facilidade para padronização e permite a obtenção de resultados mais consistentes do que o teste de frio utilizando-se "terra" em caixas, inclusive quanto à relação com a emergência das plântulas em campo.

“…Kinittle and Burris reported that single cross seeds reached a maximum seed vigor (as measured by shoot and root weight) at an SMC level ranging from 33.1% to 37.3% 17 . Rush and Neal concluded that double cross seeds achieved maximum CTG at approximately 35% SMC 29 . Thus, these works confirmed that seeds reached the IHT at a stable SMC level of approximately 35%.…”

To identify the ideal harvest time (IHT) for the seed production of XY335 and ZD958, six seed-related traits were evaluated in seeds harvested at 11 harvest stages in 8 environments. Standard germination (SG), accelerated aging germination (AAG) and cold test germination (CTG) were vigor traits; hundred-seed weight (HSW) and seed moisture content (SMC) were physiological traits; and ≥10 °C accumulated temperature from pollination to harvest (AT10ph) was an ecological trait. All the traits were significantly affected by harvest stage. The responses of SG, AAG, CTG and HSW to postponing harvest stage fit quadratic models, while SMC and AT10ph fit linear models. The IHT (indicated by the last date to reach maximum SG, AAG and CTG) were 57.97 DAP and 56.80 DAP for XY335 and ZD958, respectively. SMC and AT10ph at IHT were 33.15% and 1234 °C for XY335, and 34.98% and 1226 °C for ZD958, respectively. The period to reach the maximum HSW was 5 days later than the IHT. Compared to HSW and SMC, AT10ph had a closer relationship to the seed vigor traits. Together with the fact that AT10ph was less affected by environment, these results suggested that AT10ph may be a novel indicator for determining the IHT.
