In maize (Zea mays L.) large decreases in kernel number result when low water potentials (Psi(w)) and high temperatures occur during pollination. To gain insight into the basis for the decreased seed set, silk, pollen, and ear-leaf Psi(w), the capability for silk osmotic adjustment, and pollen appearance were measured to determine their relationship to seed set. A multiple-eared or prolific (hi...

Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS) alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage. Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and increasing yield than other treatments. However, considering cost b...

Insect pollinations of tree species with high-density populations have rarely been studied. Since the density of adults can affect effective pollen dispersal, short-distance pollination, even by insects, may frequently occur in high-density populations. To test this prediction, we investigated pollination patterns in a high-density population of the insect-pollinated canopy tree species Castano...

Methods for ranking the importance of nodes in a network have a rich history in machine learning and across domains that analyze structured data. Recent work has evaluated these methods through the "seed set expansion problem": given a subset [Formula: see text] of nodes from a community of interest in an underlying graph, can we reliably identify the rest of the community? We start from the ob...

Crown rust, caused by the fungal pathogen, Puccinia coronata Corda var. avenae W.P. Fraser Ledingham, reduces kernel quality and grain yield in oat (Avena sativa L.). Partial resistance is considered to be a durable form of rust resistance. This study sought to evaluate the feasibility of simultaneously improving partial resistance to crown rust, grain yield, and seed weight in an oat populatio...

The purity of waxy corn seed is a very important index of seed quality. A novel procedure for the classification of corn seed varieties was developed based on the combined spectral, morphological, and texture features extracted from visible and near-infrared (VIS/NIR) hyperspectral images. For the purpose of exploration and comparison, images of both sides of corn kernels (150 kernels of each v...

In India, groundnut is gown on 5.7 million hectare with a production of 4.7 million tonnes, with an average productivity of 0.8 tons haduring the rainy season and in the post-rainy season it is grown on 0.9 million hectare with a productiop of 1.5 million tonnes, and an average productivity of 1.6 t ha(Radhamani and Singh, 2008). The productivity in India is low with low seed quality. It is att...

1. Plant fecundity and seed dispersal often depend on environmental variables that vary in space. Hence, plant ecologists need to quantify spatial environmental effects on fecundity and dispersal. 2. We present an approach to estimate and model two types of spatial environmental effects: source effects cause fecundity and dispersal to vary as a function of a source's local environment, whereas ...

The seed kernel of Balanites roxburghii Planch., an underutilized species, yields a substantial amount oil and has impressive fatty acid profile. Both cake have the potential to be rich nutritive sources. With this view, in present study, profiling including HPLC quantification tocopherols phytosterols been done. Further, total phenolic content antioxidant activities also analyzed. showed good ...

We consider the spatially inhomogeneous Moran model with seed-banks introduced in [20]. Populations comprising active and dormant individuals are structured colonies labeled by Zd,d≥1. The population sizes sampled from a translation-invariant, ergodic, uniformly elliptic field that constitutes static random environment. Individuals carry one of two types: ♡ ♠. Dormant individual resides what is...
