Researches About the Influence of Reducing the Assimilation Surface on Number of Grains/Cob Corn at Some Maize Hybrids

Researches About the Influence of Reducing the Assimilation Surface on Number of Grains/Cob Corn... Abstract In this work it was analyzed the influence of reducing leaves surface on the number of grains/cob corn at four maize hybrids created at The National Institute for Researches and Development Fundulea. The results show that in the phenological phase of formation of stigmata, at studied hybrids, the most important factor which influenced the number of grains/cob corn were the last three leaves under panicle. On average, leaf removal produced losses in the number of grains /cob corn compared with the control values for all variants tested. Losses ranged between 12 and 26% compared to the control variant. The most obvious reduction in the number of grains / cob corn for analyzed hybrids were recorded in the variant where the leaves are removed from the top of the corn cob and remained only the leaf under the panicle. (74 % of control). In phenological phase of 15 days after stigmata formation, the lowest value of this character was recorded in experimental version which have been removed all the leaves above the cob corn, respectively 80 % of controls, and the maximum value of the analyzed hybrids was registered in experimental version which have been removed all the leaves below the corn cob. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annals ”Valahia” University of Targoviste - Agriculture de Gruyter
