Abstract Decomposition of leaf litter is a central process energy and nutrient cycling in forests, which arthropods hold important roles. Thus, safeguarding the diversity organisms including increasingly being considered contemporary forestry, not least to facilitate continued ecosystem functioning. Retention forestry tries achieve biodiversity conservation by preservation tree structural eleme...
Strong latitudinal patterns in leaf form are well documented in floristic comparisons and palaeobotanical studies. However, there is little agreement about their functional significance; in fact, it is still unknown to what degree these patterns were generated by repeated evolutionary adaptation. We analysed leaf form in the woody angiosperm clade Viburnum (Adoxaceae) and document evolutionaril...
Suboptimal levels of phosphorus (P) strongly inhibited leaf expansion in young cotton (Gossypium hirsutum L.) plants during the daytime, but had little effect at night. The effect of P was primarily on cell expansion. Compared to plants grown on high P, plants grown on low P had lower leaf water potentials and transpiration rates, and greater diurnal fluctuations in leaf water potential. Hydrau...
Rice (Oryza sativa) is a staple crop that supports half the world's population and an important monocot model system. Monocot leaf matures in a basipetal manner, and has a well-defined developmental gradient along the longitudinal axis. However, little is known about its transcriptional dynamics after leaf maturation. In this study, we have reconstructed a high spatial resolution transcriptome ...
grain yield loss in rice (oryza sativa l.) caused by blast disease, magnaporthe grisea (hebert) barr, is a major concern of rice growers worldwide. blast is considered as the most injurious disease of rice in iran, resulting in severe loss especially to susceptible rice cultivars. in order to assess yield loss caused by blast pathogen and develop an appropriate model, different disease onsets a...
The main focus of the study is to implement and evaluates the DCT based plant leaf disease recognition using subtractive clustering for automatic recognition and classification. The proposed methodology of the study includes image processing and recognition by classification. The method consists of four phases: First, capturing plant leaf disease images and perform color space transformation, i...
In recent years leaf curl disease of cotton has become a major limiting factor in the production of cotton, which is an important fiber cash crop. In the last two decades or more, leaf curl disease in cotton took on epidemic proportions in Pakistan. In the early 1990’s cotton leaf curl disease (CLCuD) appeared in the bordering parts of India in the states of Rajasthan and Punjab and spread to e...
