Pollen limitation, resource limitation, fruit abortion, and predation have all been proposed as factors explaining low fruit set in hermaphroditic plants. We conducted a 5-year study combining field observations and pollination experiments to determine the causes of the low fruit set in Aristolochia paucinervis, a Mediterranean species with a specialized pollination system in two populations in...

Total soluble solid (TSS) content is commercially used as fruit quality index because of its high positive correlation with sugar content. In the present study, The effect of foliar application of naphthalene acetic acid (NAA) with different concentrations (0, 25, 50, and 100 mg.L-1) at 4 true leaf and fruit set stages and plant training (pruning and thinning) on TSS and soluble sugar (i.e. suc...

in order to study adaptation ability of 15 commercial olive cultivars, this experiment was carried out using a randomized complete block design with three replication during the period from 2007 to 2009 in dry-warm climate of sar-pol-e-zehab dallaho olive station of kermanshah province. in this experiment, vegetative and reproductive traits were measured according to i.o.o.c. descriptors. flora...

Background & Aim: Deanaie thyme (Thymus daenensis Celak.), a member of the Lamiaceae family.  Thymus in one of the most important medicinal and aromatic plants that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. Recent studies have showed that thyme have strong antibacterial, antifungal, spasmolytic and antioxidant acti...

Self-compatibility of local olive (Olea europaea L.) accessions and of the cultivars "Frantoio" and "Leccino" was investigated in Garda Lake area, northern Italy. Intercompatibility was determined for "Casaliva," "Frantoio," and "Leccino," as well as the effects of foliar Boron applications (0, 262, 525, or 1050 mg.L(-1)) applied about one week before anthesis on fruit set, shotberry set, and o...

Apple is one of the fruit species in which self-incompatibility seen. For economical apple production, pollination and fertilization are required. In this study, it was aimed to determine effect different pollinators on set ratios some characteristics varieties genotypes originating from Kyrgyzstan by hybridization breeding method 2020 year. According results, highest ratio obtained with combin...

Indole Acetic Acid 9 (IAA9) is a negative auxin response regulator belonging to the Aux/IAA transcription factor gene family whose downregulation triggers fruit set before pollination, thus giving rise to parthenocarpy. In situ hybridization experiments revealed that a tissue-specific gradient of IAA9 expression is established during flower development, the release of which upon pollination tri...
