The effect of three salicylic acid (0, 50 and 100 mg l-1) and K2SO4 (0, 0.1 and 0.2 %) levels on some characteristics nut and physiological parameters of pistachio trees cv. ‘Owhadi’ were investigated. Treatments were applied at endospermic growth stage of seed and cotyledons appearance. The results showed that potassium increase yield, splitting percentage; nut fresh mass and kernel dry mass a...

Petroleum ether extract of Caesalpinia bonduc L. (Roxb) seeds (Family: Caesalpiniaceae) was evaluated for its anti-inflammatory activity in rats. Wistar rats (120-150 g) of either sex were pretreated with petroleum ether extract of seed kernel of C. bonduc. Inflammation was induced in rat paw by injecting 0.1 ml of carrageenan (1% w/v) in subplantar region of right hind paw. Inflammation induce...

environmental friendly pesticides with a natural origin can be used as an alternative to chemicals in plant pests control programs. from this perspective, the extract of ginkgo biloba l. plant is important. in this study which was conducted in 2010, the ethereal extract of exocarp and kernel of g. biloba seed was analyzed using a gas chromatograph mass spectroscope. the components included gink...

Detasseling is used in hybrid corn (Zea mays L.) seed production to ensure harvested seeds have the desired genetic complement. Both mechanical and hand detasseling result in loss of some leaf tissue and plant N. The objective of this study was to determine if seed yield and quality and N content of grain and stover were affected by leaf removal during detasseling. The treatments evaluated were...

The metabolism of (14)C-labeled fatty acids and triacylglycerols was followed in intact germinating oil palm seedlings as well as in tissue slices. In the germinating seedling, the shoot contained a normal pattern of membrane fatty acids (mainly C(16), C(18:1), C(18:2)) but the kernel contained about 68% C(12) and C(14) fatty acids. Haustorium fatty acids were intermediate between the two. [(14...

The distribution of many tree species is strongly determined by the behavior and range of vertebrate dispersers, particularly birds. Many models for seed dispersal exist, and are built around the assumption that seeds undergo a random walk while they are being carried by vertebrates, either in the digestive tract or during the process of seed storage (caching). We use a PDF of seed handling (ca...

cotton (Gossypium hirsutum L.) and related species all contain gossypol, a polyphenolic compound that is an integral part of the cotton plant’s self-defense system against insect pests and possibly some diseases. gossypol also has been reported to have antitumor activity, medicinal effects, and contraceptive properties. However, the compound can be toxic to animals, which limits the usefulness ...

The opaque-2 (o2) mutation of maize increases lysine content, but the low seed density and soft texture of this type of mutant are undesirable. Lines with modifiers of the soft kernel phenotype (mo2) called "Quality Protein Maize" (QPM) have high lysine and kernel phenotypes similar to normal maize. Prior research indicated that the formation of vitreous endosperm in QPM might involve changes i...

Seed yield of any hybrid maize (Zea mays L.) variety emerges depending on parental characteristics inbred lines used. Even though, traits each line are recorded there is no clear information about that contribute to and associations among those characters. The present study was conducted using 14 at Bako National Maize Research Centre in 2018/2019 based Randomized complete block design w...
