this study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-d and naphthalene acetamide application on yield and quality of date palm of ‘kabkab’ cultivar. the inflorescences sprayed with 2, 4-d isopropylester (0, 10, and 20 mg l-1), naphthalene acetamide (0, 80, and 120 mg l-1), putrescence and spermidine (0, 0.1, and 1.0 mm), three or six weeks after pollin...

in present research the effects of four levels (0, 0.5, 1, 2 mm) of each of salicylic acid and putrescine treatments on the quality improvement of granny smith apple fruit were studied. factorial experiment in randomized complete block with three replications on 16 trees, eighteen years in researcher station of agriculture university of tehran was designed. for this purpose the trees were spray...

Three different injectors, each 25 mm in length and with diameters of 6, 4, and 3 mm, respectively, were tested with low-pressure injections of 250 ml of water into 23 different species of fruit-trees, woodland and ornamental trees at different times of year. The 6 and 4 mm injectors performed well, yielding uptake of 75±100% of water volume 1 or 48 h after injection, depending on the species; ...

Crassocephalum rubens is a wild, economic and medicinal plant that is now threatened by genetic erosion in Nigerian ecosystem. The scarcity of the plant is due to indiscriminate collection from the wild and the difficulty in germinating the seeds. This study provides protocols for in-vitro propagation of C. rubens to supplement natural propagation, contribute to conserve the plant genetic resou...

The purpose of this study was to characterize olive core collection with amplified fragment length polymorphism (AFLP) markers and fruit traits and to determine AFLP markers significantly associated with these fruit characters in olive. A total of 168 polymorphic AFLP markers generated by five primer combinations and nine fruit traits were used to characterize relationships between 18 olive cul...

this investigation was carried out in a commercial orchard in ashtian city, markazi province. the effect of n-phenyl-phthalamic acid and nutrition on fruit quantity and quality of plum cv. maragheh was studied with the aim of increasing yield. the n-phenyl-phthalamic treatments (concentrations, 0, 500 and 1000 mg/l) were performed at full bloom (80 % flowering) on 29 march. also, nutrition was ...

The efforts were made to study the impact of vermicomposted and composted farmyard manure (FYM) along with some combination of NPK fertilizers, on field crop of garlic (Allium stivum L.). A total of six experimental plots were prepared: T1 (recommended doze of NPK), T2 (vermicompost @ 15t/ha), T3 (20 t/ha vermicompost), T4 (15t/ha vermicompost + 50 % NPK), T5 (15t/ha farmyard manure), and T6 (f...
