In: Egyptian Journal of Agricultural Research 2009.v.87(1)SPSummary: Two field experiments were conducted at EI-Baramoon Experimental Farm of Mansoura Horticultural Research Station, Horticultural Research Institute, Agriculture Research Center during 2006-2007 and 2007-2008 late fall seasons, on snap bean plants cv. Poulista. The study aimed to investigate the effect of some natural compounds as a foliar applications to alleviate the adverse effects of low temperature tolerant (cold stress), yeast (5, 10 and 15 giL), vitamin B (25, 50 and 75 ppm) and adinosin-tri-phosphate (ATP) (50,100 and 150 ppm) in two different date planting times (20th October and 10th November). The obtained results showed that, first planting time was superior than the second one, also, all applied treatments ameliorated cold stress effects and significantly enhanced all growth parameters (plant height, number of branches per plant, number of leaves per plant, leaf area and plant fresh and dry weight), increased the concentrations of leaf mineral composition (N, P and K) of their plant foliage, beside improved pod yield and pod quality. The adinosin-tri-phosphate (ATP) at (150 ppm) concentration gave significant results in both planting dates in the two seasons.
