Drought-induced changes in anthesis-silking interval are related to silk expansion: a spatio-temporal growth analysis in maize plants subjected. Anthesis silking interval (asi) was calculated with ff − mf growing degree days (gdd) at each location were calculated using the model of. Phosphorus fertilization improves growth analysis traits and reduces anthesis-to- silking interval leading to increased grain yield in maize renu pandey. In maize, a major effect of water stress is a delay in silking, resulting in an increase in the anthesis-silking interval, which is an important cause of yield failures. Introducing adaptability traits to high plant density like short anthesis-silking interval (asi) and earlier silking (dts), to the egyptian maize hybrids is of utmost.
In over 90% of the trials, ears plant−1, kernels plant−1, weight kernel−1, anthesis- silking interval (asi), tassel branch number and visual scores for leaf angle,. It corresponded to the anthesis‐silking interval used by breeders to silk emergence out of the husks is delayed while anthesis is largely. Plant density delayed days to 50% silking of maize crop ritchie and alagarswamy (2003) stated that lengthening of the time interval between anthesis and. Anthesis silking interval (asi) was computed as the interval in days between dates of silking and anthesis plant and ear heights were measured in centimeter .
Drought stimulates a protandrous pattern of development, increasing the anthesis-silking interval because maize has a short period of flowering and pollen. Qtl mapping for controlling anthesis-silking interval based on ril population in maize x liu, z zheng, z tan, z li, c he, d liu, g zhang, y luo.

The importance of the anthesis-silking interval in breeding for drought tolerance in tropical maize j bolafios , go edmeades maize physiologists, cimmy~.
The anthesis to silking interval (asi) is highly correlated to grain yields under drought stress as shown by experiments conducted at cimmyt,. Days to 50% silking, anthesis-silking interval, plant height, ear height, number phenotypic correlation with anthesis-silking interval (rg = 094, p = 001 and (rp. The anthesis to silking interval (asi) is highly correlated to grain yields under drought stress as shown by experiments conducted at cimmyt, mexico this study.

Minimum (57 days, 59 days, 2 days and 94 days) days to anthesis, days to silking , anthesis to silking interval (asi) and days to maturity was recorded by azam-3,.
Plant height, asi (anthesis to silking interval), panicle length, and the weight of 100 seeds have been used to test maize tolerance to sub-optimum conditions  . A short anthesis-silking interval (asi) (ribaut et al 1997) is an indicator of these effects and has been used effectively in selection for improved yield under. To 50% tasselling, pollen shed and silking anthesis-silking interval, anthesis- silking interval was estimated as the difference between.
Among these, anthesis silking interval, plant height, ear height, kernel rows per cob, cob length and cob diameter are significantly important [6. Among the yield components revealed the significantly positive association of grain yield with anthesis silking interval, ear length, ear girth,.
Of the anthesis-silking interval (asi) a short asi has been identified as an easily measured, visual trait which may identify enhanced drought tolerance in maize. Emergence, results in increasing anthesis silking interval (asi) this asynchrony between male and female flowering time is regarded to be. Asynchrony of pollen shed and silking • silk elongation requires high water potential― drought stress can delay silking and increase the anthesis-silking interval.
