waterlogging is one of the problems of cotton-growing in rainy regions which affects adversely plant growth in the early stages. so that rainfall causes waterlogging in early to mid spring in the fields without proper drainage. also, rainfall declines soil and environment temperatures. to investigate the effects of waterlogging period duration and temperature on vegetative properties and glycol...

Common features in the time-course of expansion of leaves which considerably differed in final area, due to phytomer position, growing conditions and genotype, were identified. Leaf development consisted of two phases of exponential growth, followed by a third phase of continuous decrease of the relative expansion rate. The rate and the duration of the first exponential phase were common to all...

Nitrogen deficiency severely inhibits leaf growth. This response was analysed at the cellular level by growing Lolium perenne L. under 7.5 mM (high) or 1 mM (low) nitrate supply, and performing a kinematic analysis to assess the effect of nitrogen status on cell proliferation and cell growth in the leaf blade epidermis. Low nitrogen supply reduced leaf elongation rate (LER) by 43% through a sim...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Festuca L. comprises perennial herbs and about 450 species. It belongs to the tribe Poeae R. Br. (= Festucaceae Dumort), subfamily Pooideae of Poaceae. These species are different in leaf size, life duration and lamina width. The genus is divided into two groups based on lamina width: fine-leaved and broad-leaved. In this study, leaf anatomy of F. akhanii, F. elwendiana,F. heterophylla, F. sulc...

BACKGROUND Breast engorgement is a condition that affects breastfeeding mothers early in the postpartum. The discomfort and tenderness as a result of the engorgement is a major contributing factor to the early cessation of breastfeeding. Many treatments for breast engorgement have been attempted and explored. OBJECTIVE To examine the effectiveness of cabbage leaf treatment on pain and hardnes...

Leaves show a wide range of shapes that results from the combinatory variations of two main parameters: the relative duration of the morphogenetic phase and the pattern of dissection of the leaf margin. To further understand the mechanisms controlling leaf shape, we have studied the interactions between several loci leading to increased dissection of the Arabidopsis leaf margins. Thus, we have ...

The speech synthesis system described in this paper uses a set of speaker-dependent decision-tree state-clustered hidden Markov models to automatically generate a leaf level segmentation of a large single-speaker continuous-read-speech database. During synthesis, the phone sequence to be synthesised is converted to an acoustic leaf sequence by descending the HMM decision trees. Duration, energy...
