Host Preference of (Hendel) (Diptera: Tephritidae) Among Fruits of Solanaceous Plants.

Host preference of (Hendel) (Diptera: Tephritidae), major chili and nightshade pest, was studied using seven host plant species of family Solanaceae. Two nightshade species, eggplant, L. and turkey berry, Sw.

Impact of the Ripening Stage of Wax Apples on Chemical Profiles of Juice and Cider.

Wax apple fruit ( Alston cv. Taaptimjan) is a tropical fruit with many nutritional bioactive compounds and high economic value. However, when fully ripe, the thin-skinned fruit is highly susceptible to physical damage and microbial spoilage that significantly reduce its commercial value.

Supplying nitrate before bud break induces pronounced changes in nitrogen nutrition and growth of young poplars.

Tree nutrient research concentrated on endogenous C and N remobilisation in spring has neglected to acknowledge the possibilities of significant effects of N uptake before bud break, especially on the quality of regrowth and N reserve remobilisation. To investigate this subject, experimental studies were performed on young poplars (Populus tremula×Populus alba, clone INRA 717-1B4) grown with a controlled nutrient supply: (i) without N, 'control'; (ii) N supplied throughout the course of the experiment, 'N-supply'; and (iii) N supplied only before bud break, 'N-pulse'. Results confirm the hypothesis that poplar scions can significantly take up nitrate before bud break, amounting to ~34% of the total N stored the previous year.
