Define anthesis silking interval
Abstract when maize (zea mays l) is stressed at flowering because of deficits of water, light, nutrients, and sometimes by long photoperiods and lack of thermal adaptation, ear growth slows in relation to tassel growth and the anthesis-silking interval (asi) increases. Anthesis silking interval james rilling, associate professor of anthropology at emory university in atlanta 400 mg prezzo do not bolt out anthesis silking interval the room right after the baby is born to issue a press release. Increase in the anthesis-silking interval, which is an important cause of yield failures diverse strategies are used by breeding programs to improve drought tolerance conventional breeding has improved the drought tolerance of temperate maize hy-. During maize (zea mays l) growth and change of anthesis-silking interval (asi) is one of the most serious consequences to realize the genetic basis of asi, a . Finance graduate resume objectives anthesis silking interval best you most likely already know that finance graduate resume objectives anthesis silking interval best is one of the most popular issues on the net at this time.

In general, the ler models performed better than gblup for all datasets and particularly well for traits with a complex genetic architecture, ie, generated by a large number of genes with small effects, eg in the maize dataset, for growing degree days to anthesis (gdd_dta) and to silking (gdd_dta), anthesis-silking interval and plant height . This shorter anthesis silking interval may mitigate the impact of drought stress during pollination for more on the pollination process in corn check out the following abendroth, lj, rw elmore, mj boyer, and sk marlay 2011. Asi is defined as anthesis silking interval somewhat frequently this definition appears somewhat frequently see other definitions of asi other resources: .
The longer anthesis-silking interval are undesirable for grain yield production as the male and female parents do not synchronize well on the other hand, materials . Combining, earliness, short anthesis to silking interval and yield based selection indices under intermittent water stress to select for drought tolerant maize kahiu ngugi, juma ogeto collins, sicily muchira. Anthesis silking interval term accession: to:0000463 aspect: plant_trait_ontology synonyms (3) antskit, asi, flwslkinter definition: a difference of the average . X e mean squares observed for anthesis-silking interval, grain yield, plant height, root lodging and plant stand makes these traits more reliable as part of an index for the selection of.
In maize (zea mays l), progress towards pistillate flower maturity (silking) is highly dependent upon the environmental conditions around floweringunder conditions that inhibit plant growth, female flower development is delayed relative to that of the male flowers resulting in an increase in the anthesis–silking interval (asi). Means for anthesis to silking interval, ears per plant, kernel weight, grain yield, days to anthesis and days to silking of parental genotypes planted in 2009 long-rains season at kiboko research centre. When maize (zea mays l) is stressed at flowering because of deficits of water, light, nutrients, and sometimes by long photoperiods and lack of thermal adaptation, ear growth slows in relation to tassel growth and the anthesis-silking interval (asi) increases. And female (silking) floral maturity, referred to as the anthesis–silking interval (asi) many studies have shown that maize yield also is a function of crop growth rate around flowering. Stress is a delay in silking resulting in an increase in the anthesis-to-silking interval (asi), incomplete or nil fertilization, and decreased or nil kernel development (hall et al, 1984) by evaluating maize that is moisture-.

Means for anthesis to silking interval, ears per plant, kernel weight, grain yield, days to anthesis and days to silking of parental genotypes planted in 2009 long . Anthesis silking interval synonyms: asi definition: a difference of the average number of days between the maize tassel flowering and the first visible silk . The anthesis-silking interval (asi) was calculated as the days to 50% silking minus days to 50% anthesis some plots under severe mois- ture stress failed to reach 50% silking approximately 30 to 40 d after 50% anthesis, and were declared missing values.

Full-text paper (pdf): anthesis to silking interval usefulness in developing drought tolerant maize. Delay in silking leads to a long anthesis to silking interval (asi) and therefore poor kernel set a study was conducted in 2008/2009 at kiboko and kabete field station and the objectives were: (i) to evaluate parental lines under managed stress environment and (ii) to select genotypes from segregating populations using earliness and anthesis .
