Advanced flowering plants

Ebook "The dawn angiosperms: Uncovering the origin of flowering plants" discusses the controversial and conflicting hypotheses on the origin of angiosperms, which was generally assumed to be restricted to the Cretaceous and later ages. Since publishing the first edition of “The Dawn of Angiosperms” in 2010, several important advances have been made in this field of science.

Ebook "Epigenetic memory and control in plants" highlights recent advances in our understanding of epigenetic mechanisms as a major determinant through which internal and external signals, such as those occurring during hybridization, flowering time, reproduction and response to stress, communicate with plant cells to bring about activation of multiple nuclear processes and consequently plant growth and development. The outcome of these processes may persist for generations long after the initial cues have expired and may contribute to plant evolution.

In this review we have discussed a few important hi – tech practices in the fruit crop mango. The novel techniques that cab be adopted to improve the mango productivity are High Density Planting, fertigation technology under UHDP, mulching, canopy management, using of growth regulators, floral manipulation by application of exogenous plant hormones, induction of off – season flowering, ethylene spray, paclobutrazol and top working of old and senile orchards for rejuvenation. When all these techniques are integrated and practiced, there will be remarkable increase in productivity of mango.
