Seed Physiology And Biochemistry (vol.2: Seed Dormancy And Germination) Hb NEW
The dormancy is favourable for wild types and few cultivated species.
To preserve the genetic diversity of crops species dormancy is found to be beneficial for wild types.
While in cultivated species, this existence protects the seeds from insitu germination under unfavourable climatic condition if not harvested at right time of physiological maturity and the best example is wheat, rice, etc.
Dormancy induction, maintain and release mechanisms are induced by many factors and one among is the plant hormones, ABA and GA.
ABA sensitive mechanism favours dormancy induction and induction, whereas GA sensitivity releases dormancy, which induces germination of non-dormant seed.
Besides hormones, the substances like NO, HCN and �-mannanase mediate dormancy release.
Factors such as water, oxygen, temperature etc.
play a paramount role in germination mechanisms which involve imbibition, GA de nova synthesis that triggers enzyme production.
The hydrolytic enzymes helps in breakdown of complex food materials into simpler ones which are transported in to scutellum and supplies to the growing radicle and plumule.
The cell cycle acting in the post-germination phenomenon that leads to cell division.
In order to understand, the physiology and biochemistry of dormancy mechanisms and release as well as the mechanisms end process of germination the book �Physiology and Biochemistry of Seeds: Volume 2 � Seed Dormancy and Germination.
This volume acts as a guide to researchers, scientists, teachers and students of seed science and technology and crop physiology.
Dr. (Prof.) Vanangamudi K
Dr. K. Vanangamudi former Dean
(Agriculture), is now working as a Professor of Seed Science and Technology. He
was the Co-Principal Investigator of the ICAR NAIP scheme on Development of
e-course materials for B.Sc.,(Ag) Degree programme. He is the Principal
Investigator of GOI-NIMI schemes on Development of Instructional materials for
ITI students in Agriculture sector and Development of Instructional materials
for COE both BBBT and advance modules. He was the former Dean (Agriculture),
Agricultural College and Research Institute, Tamil Nadu Agricultural
University, Coimbatore from March 2006 to July 2009, former Dean of AP
Agricultural College, TNAU, Kalavai, Vellore district from September 2003 to
February, 2006 and former Professor and Head of Dept. of Seed Science &
Technology, TNAU, Coimbatore -3 from March 2001 to August 2003.
During his tenure as Dean
(Agri) he started three new UG degree progarmmes namely B.Tech (Bioinformatics)
in 2006-07, B.Tech (Agricultural Information Technology) in 2007-08 and BS
(AgriBusiness Management) in 2007-08.
As a faculty Dean of TNAU, Dr.
Vanangamudi is having a rich experience in e-education. Introduced e-learning,
e-teaching, e-class, e-registration, e-attendance, e-communication,
e-assignment, online examination and e‑evaluation
in UG education of TNAU. This is implemented for 12 UG degrees being offered at
10 constituent and 4 affiliated colleges.
He established e-learning lab,
e-class room, e-examination hall and WiFi connectivity in the boys and girls
hostels of all the colleges of TNAU. Owning of laptop is the mandatory for all
UG students.
He encouraged the teachers to
develop webnotes and hosted in the TNAU website. He also introduced interactive
method of teaching, off class mode of teaching, videoconferencing and video
streaming. The teachers lecture presentations in the class room are video
captured, edited and hosted in TNAU website. He introduced many new courses
including Nanotechnology in UG degrees. He is trained in e-learning and web
based teaching at University of California, Davis and Cornell University, USA.
