Morphological characterization of 15 genotypes viz. Navona, Malesco, Litouwen, Black Out, Revenna, Pink Palace, Tiber, Conca-D, Nello, Yellow Diamond, Tresor, Rialto, Courier, Cobra, Pavia was carried out during year 2018 at Division Of Floriculture and Landscape Architecture SKUAST- K Shalimar with an objective to assess the response traits growth propagation ratio. On basis data maximum plant...

The genetic architecture of the total phenotype may substantially constrain or enhance the evolution of floral color within populations in response to multiple selection pressures. Using Claytonia virginica I previously identified opposing selection on floral color generated through herbivores and pathogens. Here I ask whether the evolution of floral color in this system is constrained or uncon...

In the last five decades, use of rootstocks and scions has changed, along with their systems cultivation. Associated climate change, fruit trees face new ecological phytopathological challenges. Rootstocks affect generative vegetative performance a scion, such as productivity, span nonbearing period, growth vigor, shelf-life quality fruits. According to recent study, they also frost tolerance f...

1. Many plants engage ants in defensive mutualisms by offering extrafloral nectar (EFN). Identifying sources of variation in EFN quantity (amount) and quality (composition) is important because they can affect ant visitation and identity and hence effectiveness of plant defence. 2. I investigated plant size and reproductive state (vegetative or flowering) as sources of variation in EFN quantity...

Abstract. Information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. Vetiver grass (Vetiveria zizanioides) is a non-native perennial grass that was introduced to the Iran in 2008. This plant is a multi use species that could be considered from different viewpoints. Thus, it...

Heterosis is important for agriculture; however, little is known about the mechanisms driving hybrid vigor. Ultimately, heterosis depends on the interactions of specific alleles and epialleles provided by the parents, which is why hybrids can exhibit different levels of heterosis, even within the same species. We characterize the development of several intraspecific Arabidopsis (Arabidopsis tha...

Diet and helminth fauna were analysed in Gallotia caesaris, a small lacertid lizard endemic to El Hierro (Canary Islands, Spain) in order to study the evolutionary and functional relationships between the two traits. This species is omnivorous but consumed a high proportion (82.13%) of plant matter including not only seeds but also leaves and other vegetative parts. Helminth fauna included many...
