Physiological Basis of Stagnant Flooding Tolerance in Rice

Parameters and Secondary Characters for Selection of Tolerance Rice Varieties under Stagnant Flooding Condition

“…Genotypes with moderate stem elongation had higher survival and yield under flooding conditions. As mentioned by (Kuanar et al, 2017) many different types of traditional rice varieties are being grown by the farmers. The local landraces adapted to extreme in water availability could be the sources of new gene(s, medium elongation is important for higher plant productivity under SF.…”

“…The ability of rice adaptation to long-term stagnant flooding depends on combination of morphological and physiological adaptation (Kuanar, Ray, Sethi, Chattopadhyay, & Sarkar, 2017)many different types of traditional rice varieties are being grown by the farmers. The local landraces adapted to extreme in water availability could be the sources of new gene(s. The selection of secondary characters was considered effective if they were expressed constitutively, could be observed as early as possible such as in seedlings or vegetative stages.…”

Yield and photochemical activity of selected rice cultivars from Eastern India under medium depth stagnant flooding

“…Overexpression of two genes, such as SNORKEL 1 (SK1) and SNORKEL 2 (SK2), allows rice to outgrow the rising floodwaters (Hattori et al 2009) and thus, plants escape complete inundation. However, under medium depth (≈ 50 cm water depth) conditions, such extensive elongation is not warranted (Kuanar et al 2017, Singh et al 2017. Extensive elongation leads to heavy yield penalty.…”

“…Extensive elongation leads to heavy yield penalty. In order to adapt to medium depth water stagnation in addition to slow elongation, numbers of morphological, anatomical, and physiological changes are necessary even in rice (Striker 2012, Kuanar et al 2017.…”

Predicting Some Physicochemical Properties of Octane Isomers: A Topological Approach Using <em>ev</em>-Degree and <em>ve</em>-Degree Zagreb Indices<strong> </strong>

“…Octane isomers have been used widely in QSPR studies. The role of octane isomers in QSPR studies, we refer the interested reader [1][2][3][4] Very recently, Chellali, Haynes, Hedetniemi and Lewis have published a seminal study: On ve-degrees and evdegrees in graphs [5]. The authors defined two novel degree concepts in graph theory; ev-degrees and ve-degrees and investigate some basic mathematical properties of both novel graph invariants with regard to graph regularity and irregularity [5].…”
