Abstract Water is essential for the growth period of crops; however, water unavailability badly affects the growth and physiological attributes of crops, which considerably reduced the yield and yield components in crops. Therefore, a pot experiment was conducted to investigate the effect of foliar phosphorus (P) on morphological, gas exchange, biochemical traits, and phosphorus use efficiency (PUE) of maize (Zea mays L.) hybrids grown under normal as well as water deficit situations at the Department of Agronomy, University of Agriculture Faisalabad, Pakistan in 2014. Two different treatments (control and P @ 8 kg ha⁻¹ ) and four hybrids (Hycorn, 31P41, 65625,… More >

Abstract Pinus maximartinezii (Rzedowski) is an endemic endangered species, confined to a single population of approximately 2000 to 2500 mature trees. It covers about 400 ha in southern Zacatecas, Mexico. The success of tissue culture techniques for germplasm preservation depends on regeneration of cultures. The objective of this study was to achieve an in vitro proliferation protocol using organogenesis technique for Pinus maximartinezii. Mature seeds were surface sterilized in 6% H2O2 v/v. Isolated cotyledons and zygotic embryos were cultured on shoot induction media. DCR and GD media were supplemented with 0.3 and 0.5 mgl-1 BAP; 0.01 mgl-1 ANA and vitamin solution.… More >
