The experimental factors were: A - nitrogen fertilization: A1 - 60 kg N*ha-1, A2 -120 kg N*ha-1; B - bioregulators application: B1 - NPH, B2 - TE, B3 - CCC, B4 - TE + NPH, B5 - CCC + NPH, B6 - no bioregulators (control).
These authors found that the effects of the biostimulant on plants change under stress conditions, which indicates that a set of ecophysiological factors, together or separately, may interfere with the performance of bioregulators (Albrecht, Braccini, Scapim, Avila, & Albrecht, 2012).

Despite numerous studies on thiourea acting as effective bioregulator imparting resistance to crop plants against abiotic stresses (Srivastava et al., 2009; Anjum et al., 2011; Perveen et al., 2013); to the best of our knowledge, no study has been conducted to elucidate the influence of exogenously applied thiourea on membrane stability and antioxidant defense system of wheat under heat stress.
SA is responsible for aspirin's renowned effects in relieving pain and inflammation, and, according to the new study, it may be the first in a new class of bioregulators.
Azimi et al [1] indicated that SA bioregulator can increase 1000-kernal weight by change in photosynthesis through increase in photosynthetic pigments.
Since seeds' treatment has been increasingly used and the level of seeds' vigor may interfere with the action of regulators present in the Stimulate[R] of stored corn seeds, the objective of this present study was to assess the effects of the bioregulator Stimulate[R] about seed treatment on physiological quality of maize seeds in different periods of storage.

Bacillus are recognized as bioregulators and natural antagonists of several phytopathogens, in addition to promoting growth and inducing resistance in plants (MAHDY et al., 2001; VONDERWELL et al., 2001; ONGENA & JACQUES, 2007; RUSSI, 2012).
They present a combination of desirable attributes as bioregulators such as their wide host range, the ability to cause high insect mortalities, their environmental friendliness, their facile production at different scales by methods both in vivo and in culture, and the compatibility with various chemicals and other bioregulatory agents (Shapiro-Ilan and Dolinski 2012).
