Pentacyclic triterpenes are secondary plant metabolites widespread in fruit peel, leaves and stem bark. In particular the lupane-, oleanane-, and ursane triterpenes display various pharmacological effects while being devoid of prominent toxicity. Therefore, these triterpenes are promising leading compounds for the development of new multi-targeting bioactive agents. Screening of 39 plant materi...

The nutritional economy of the fruit of cowpea (Vigna unguiculata (L.) Walp cv Vita 3) was assessed quantitatively from intake and utilization of carbon, nitrogen, and water. Fruits failed to make net gains of CO(2) from the atmosphere during daytime, although pod photosynthesis did play a role in the fruit's carbon economy by refixing a proportion of the fruit's respired CO(2). Of every 100 un...

for evaluation of iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 iranian onion morphotypeswere collected from east azarbaijan (redazarshahrmorphotypes), tehran (red rey morphotypes), razavi khorasan (red neyshaboormorphotypes) and zanjan (gholyghese morphotypes). these onion morphotypes were planted inrcbd design in four replications in seed and p...

development of ultrasound technique has not been progressing for evaluating the internal quality of fruits as fast as that of processed foods. in this research for quality assessment of pear fruit (shah miveh variety) an ultrasonic measurement system was constructed to transmit and receive the ultrasonic waves. the apparatus included a pulser-receiver, a pair of 75 khz ultrasonic transducers wi...

BACKGROUND AND AIMS Dry fruits remain around the seeds at dispersal in a number of species, especially the Brassicaceae. Explanations for this vary, but usually involve mechanisms of innate dormancy. We speculate that, instead, a persistent fruit may give additional protection through control of dehydration, to species growing in arid or Mediterranean environments where water is sporadic. MET...

Dry matter, oil content and fatty acid composition of avocado fruit (Persea americana, cv. Fuerte and Hass) were examined with respect to the harvesting and post-harvest ripening period. Fruits were harvested in November, December, and January at onemonth intervals. Samples were kept for 8 days under ambient conditions to ripen. Dry matter and oil content of both cultivars increased significant...

To improve the yield of sweet peppers in Japan, we investigated relationships between plant growth characteristics and fruit yield, with a particular focus on dry matter production. Fruit fresh weight (i.e., yield) was highly correlated weight. Aboveground production both light use efficiency intercepted photosynthetically active radiation. Although number fruits set ratio, no correlation found...

the objective of the present field experiment was to examine how plant density and enhanced source, i.e. thinning treatments, may affect grain yield and its components for a non-prolific maize hybrid, sc704. the environment of the hybrid maize crop was changed at intervals over its life cycle by removing every other plant in rows equispaced at 75 cm apart with a population of 13.34 plants m...
