ABSTRACT
Empowerment of wheat genotypes by application of growth regulators, compatible solutes and plant extracts under water restriction is an important strategy for getting sustainable yield. This study aimed to evaluate the effects of drought stress on the growth and yield of wheat genotypes and also monitor and compare the role of ABA, SA as well as moringa and mulbery leaf water extracts in improving drought tolerance of wheat genotypes. The work was performed at the research area of the Faculty of Agricultural Sciences, Ghazi University, Dera Ghazi Khan, Pakistan. Three wheat cultivars Aas-2011, Faisalabad- 2008 and Triple dwarf-1 were subjected to drought stress (skipping the irrigation at grain filling stage). The wheat genotypes were subjected to treatments viz., T1 i.e. All normal irrigation without application of abscisic acid (ABA), salicylic acid (SA), moringa (MLE) and mulberry leaf water extract (MBLE), T2 i.e. skipping the irrigation at grain filling stage and application of 2µM ABA, T3 i.e. skipping the irrigation at grain filling stage and application of 10 m mol SA, T4 i.e. skipping the irrigation at grain filling stage and application of 15% MLE and T5 i.e. skipping the irrigation at grain filling stage and application of 10% MBLE. The experiment was laid out in Randomized Complete Block Design with factorial arrangement and repeated three times. From this study it is concluded that Aas-2011 shown best result under drought condition by applying growth regulators and plant water extracts.
RESUMO
O fortalecimento de genótipos de trigo pela aplicação de reguladores de crescimento, solutos compatíveis e extratos vegetais sob restrição hídrica é uma importante estratégia para obtenção de produção sustentável. Trilha de campo foi realizada na área de pesquisa da Faculdade de Ciências Agrárias, Universidade de Ghazi, Dera Ghazi Khan, Paquistão. Três cultivares de trigo Aas-2011, Faisalabad-2008 e Triple anão-1 foram submetidas a estresse hídrico (pulando a irrigação no estágio de enchimento de grãos). Os genótipos de trigo foram submetidos a tratamentos, T1, ou seja, irrigação normal sem aplicação de ácido abscísico (ABA), ácido salicílico (SA), moringa (MLE) e extrato de água de amoreira (MBLE), T2¬, pular a irrigação em estágio de enchimento de grãos e aplicação de ABA 2µM, T3 ou seja, ignorando a irrigação no estágio de enchimento de grãos e aplicação de 10 m mol SA, T4 ou seja, ignorando a irrigação no estágio de enchimento de grãos e aplicação de 15% MLE e T5 ou seja, ignorando a irrigação no enchimento de grãos estágio e aplicação de 10% MBLE. O experimento foi exposto no delineamento de blocos completos casualizados com arranjo fatorial e repetido três vezes. A partir deste estudo conclui-se que Aas-2011 apresentou melhor resultado sob condição de seca, aplicando reguladores de crescimento e extratos de água de plantas.
