We present an algorithm and an implementation to insert broadleaves or needleleaves into a quantitative structure model according to an arbitrary distribution, and a data structure to store the required information efficiently. A structure model contains the geometry and branching structure of a tree. The purpose of this work is to offer a tool for making more realistic simulations of tree mode...

Twenty-two isolates of Sclerotium rolfsii causing spotted leaf rot from Varanasi, India were grown on 6% Cyperus rotundus rhizome meal agar (CRMA) medium for the induction of athelial stage (Athelia rolfsii). Only one isolate obtained from Sphaeranthus indicus formed basidial stage on CRMA medium while the other 21 isolates did not. Basidial stage was also produced in S. indicus isolate at diff...

one of the most important practices in flue-cured tobacco farming is topping and sucker control at the right time. topping cause's development and root growth, drought tolerance, reduce deployment pests, increased synthesis of nicotine. this study was conducted in randomized complete block design (rcbd) with 10 treatments in 3 replications over two years (2008-2009) at tirtash research and educ...

In this study, the differences in reactive oxygen species (ROS) generation and abscisic acid (ABA) accumulation in senescing leaves were investigated by early-senescence-leaf (esl) mutant and its wild type, to clarify the relationship among ABA levels, ROS generation, and NADPH oxidase (Nox) in senescing leaves of rice (Oryza sativa). The temporal expression levels of OsNox isoforms in senescin...

Temperature is one of the main environmental factors involved in global warming and has been found to have a direct effect on plants. However, few studies have investigated the effect of higher temperature on tropical crops. We therefore performed an experiment with a tropical crop of Habanero pepper (Capsicum Chinense Jacq.). Three growth chambers were used, each with 30 Habanero pepper plants...

BACKGROUND AND AIMS The mechanisms involving light control of vitamin C content in fruits are not yet fully understood. The present study aimed to evaluate the impact of fruit and leaf shading on ascorbate (AsA) accumulation in tomato fruit and to determine how fruit sugar content (as an AsA precursor) affected AsA content. METHODS Cherry tomato plants were grown in a glasshouse. The control ...

To evaluate the cultivar variation in photosynthetic rate (Pn) of mango, observations were taken in 25 cultivars representing different agro-climatic region of the country at two stages i.e. full bloom (March) and developed fruit stage (May). Seven cultivars, Papatio, Lucknow Safeda, Neelam, Mulgoa, Khas-ul-khas, Himsagar and Nisar Pasand showed the higher Pn rate at both the stages, while nine...
