drought stress has been well documented as an effective parameter in decreasing crop production, developing and releasing new varieties which are adaptable to water deficit conditions can be a constructive program to overcome unsuitable environmental conditions. in order to evaluate the adaptation of rice genotypes to drought stress and to identify the tolerant and sensitive genotypes, 15 genot...
the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...
The aim of the paper is to study a global structure of solutions of four differential inequalities αiy i(t)yi+1 ≥ 0, yi+1(t) = 0 ⇒ y ′ i(t) = 0, i = 1, 2, 3, 4 , αi ∈ {−1, 1}, α1α2α3α4 = −1 with respect to their zeros. The structure of an oscillatory solution is described, and the number of points with trivial Cauchy conditions is investigated.
In [Paper, Algorithms 1 and 2] we need the gradient of the residuals dg(Y(ri),Yi) (here, Y(ri) is equal to X1(ri)) with respect to the base point Y(ri) in order to compute the jump conditions for the adjoint variable λ1. The residual measures the squared geodesic distance between the point Y(ri) on the fitted curve and the corresponding measurement Yi. To derive this gradient, we consider the c...
The averages {nSn = n −1 ∑n i=1 Yi} of many real-valued processes are known to satisfy the LDP, including {Yi} being i.i.d. random variables or satisfying mixing conditions that are broad enough to encompass Doeblin recurrent Markov chains (e.g. Bryc and Dembo [1]). If the tail of the distribution of Y1 decays no slower than an exponential, then the scale for the LDP is the number of summands, ...

Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
