1. The fungus-gardening ants and their fungi represent a highly co-evolved, vertically transmitted mutualism. Mutualisms such as these are thought to be reciprocal antagonisms, so that the ants and the fungus can be expected to have some conflicting interests. 2. This paper reports the results from a cultivar switch experiment that documented the effects of switching the native cultivar from th...

Background: Wheat (Triticum aestivum L.) is the most important cereal crop throughout India and other parts of world. In late sowing conditions variety selection, seed rate row spacing an factor for a better yield. Higher narrow are used in as compared to normal conditions. Methods: The present field experiment was conducted at Students Research Farm, Khalsa College, Amritsar, Punjab, during ra...

The effect of water deficit on stem reserve mobilization and sink activity in wheat (Triticum aestivum L.) cultivars, viz., C306 (drought tolerant) and PBW343 (drought sensitive) was studied. Drought was maintained in pot raised plants by withholding irrigation at 95 days after sowing (DAS), i.e. just five days before the initiation of anthesis. Drought induced a significant reduction in mean b...

It is shown that inverse quantum Zeno effect (IZE) may exist in a three-level system with Rabi oscillations between discrete atomic states. The experiment to observe IZE in such a system is proposed. PACS numbers: 03.65.Bz

Here, we present the chloroplast genome sequence of the Saccharum hybrid cultivar RB867515, the most planted sugarcane cultivar in Brazil.

An investigation was carried out with nine green leafy vegetables (GLV’s) with their popular varieties most commonly grown in India to determine their biochemical composition. Among leafy vegetables ascorbic acid was found maximum in Chenopod cultivar Bathua Local (60.6 mg/100 g fw.) followed by Pusa Bathua -1 (23.0 mg/100g fw.) and spinach cultivar PS-1 (51 mg/100 g fw.). Significantly high le...

Heterodera glycines is a cyst nematode that causes significant lost soybean yield in the U.S. Recent studies observed the aphid Aphis glycines and H. glycines interacting via their shared host, soybean, Glycine max. A greenhouse experiment was conducted to discern the effect of A. glycines feeding on H. glycines reproduction. An H. glycines-susceptible cultivar, Kenwood 94, and a resistant cult...
