Benefits or feature :   Which cue stick is more effective on retail signs?Dr . B. Behe , Michigan State UniversityBetter understanding consumer behavior , preference , and trends is a key HRI research priority . This project addresses that direct . Dr. Behe antecedently discovered that younger customer are more likely to buy a branded plant – even when identical to a nonbranded works – and that consumers in general want more info on signs because they can not ascertain plant attribute by looking at it . Now Dr. Behe will take the next stride and quantify and profile what cues trigger plant option , including which benefits resonate best with which type of consumers .

Finding the ‘ Third Space ’ through gardening : strengthen kinship mutuality and lowering stress in the caregiver and tutelage receiver who has a disabling injury or illnessDr . A. Catlin , Kaiser Permanente Rehabilitation CenterCaregivers , whether it ’s a mate , partner , family member , champion , or neighbor , may fondly provide postulate upkeep to persons with a disabling sickness or impairment but often digest significant cost to their own genial and physical health in the process .

Dr. Catlin and her team will evaluate the remedial value of a shared gardening experience between the caregiver and the caution recipient .

underlying aspects of auxin foliar spray applications to woody plant cuttingsDr . R. Geneve , University of KentuckyApplying auxin as a foliar spray has several advantages over traditional quick free fall methods for settle cuttings , such as potential improved worker condom and coating efficiency . Foliar auxin sprays are also becoming an integral part of multiplication systems using automated , machine - assisted sticking robotics . However , not all woody species respond to foliar spray as well as a quick dip covering for rooting , and there are questions touch covering timing as well as the optimal routine of applications .   Basic questions about auxin movement in cuttings relate to spray volume , single vs. multiple applications , and use of a surfactant will be address .

Enhancing the performance of SSG as a biocontrol agent for ornamental plant disease mitigationDr . P. Kong , Virginia TechBoxwood blight , caused byCalonectriapseudonaviculata , is a huge business organization in the glasshouse and landscape direction industries . Control options are currently limited to cultural practice session and antimycotic agent . Biocontrol is a missing component . Bacterial endophytes ( being that pass at least part of their life history in flora roots ) have been name that show potential to reduceC.pseudonaviculatain culture . A squad led by Dr. Kong will further evaluate these endophytes for real humans applicability .

develop environmental and ethnic protocol for the production of containerized succulents in greenhouses and nurseriesDr . R. Lopez , Michigan State UniversityConsumers adore succulents . Statistics show a 79 % increase in output from 1998 to 2014 , in response to consumer demand . Over 1,000 genera of succulents ( 11,000 + coinage ) exist , and propagation and finishing needs vary greatly among them . Dr. Lopez and his team have identify cultivars of Aloe sp . , Aeonium sp . , Crassula sp . , Echeveria sp . , Gasteria sp . , Graptoveria sp . , Haworthia sp . , Kalanchoe sp . , Sempervivum sp . , Sedum sp . , and Senecio sp . to optimize propagation and the production growing environment to boil down growing metre and increase profitability .

A sustainable approach to Phytophthora - infested landscape painting beds : the lookup for resistant or resistive yearly and herbaceous perennialsDr . I. Meadows ; North Carolina State UniversityPhytophthora source rot and stem blight affects over 100 of the most democratic and most usually used landscape painting perennial and annuals , including annual vinca , petunia , and daylily , throughout the U.S. Current recommendation for infested landscape painting beds are either Laputan or not economically feasible for landscapers and homeowners . Previous research has given hope of reduce inoculant through the purpose of crop revolution with resistant plants . Dr. Meadows previously identified 14 cultivar of blossoming annuals and 8 cultivar of herbaceous perennials that performed good to excellent in landscape layer heavily infested with Phytophthora . The squad will test additional cultivar .

Using Grow Wise , Bee Smart and Oregon Bee Project Plant Picks to promote pollinator - attractive nursery plants in OregonDr . A. Melathopoulos , Oregon State UniversityPollinator wellness stay on to be a focus for our industry . Many cultivator have responded to public concerns and now adhere to HRI ’s recommended best management pattern geared to better protect pollinators during production . They have also shifted their harvest selection to let in more plants known to attract pollinator to meet consumer want . However , little research has been conduct to valuate the actual impact of these changes . Dr. Melathopoulos and his team will tax the impact of HRI ’s Grow Wise , Bee Smart and the Oregon Bee Project ’s Bee Plant Picks on the world ’s recognition of our industry ’s movement and increased sale and profits for growers .

Automation in container nursery weed controlDr . J. Neal , North Carolina State UniversityWeeds are problem . They vie with crop for water system , food , and quad . One estimate cites that a single large crabgrass plant can reduce the dry weight of a containerized Japanese holly as much as 60 % . Herbicides can help ; however , sufficient options do not survive to control broadleaves in container after emergence . Therefore , grower resort to hand Labour , that can be as much as $ 4000 / ac / class . Mechanization is a potential fix . Dr. Neal and his team contrive to develop and test a paradigm software system subject of deliver targeted postemergent or preemergent weed killer to the containers .

In defense of nativars : equate the conservation time value of native milkweed cultivars and square species for monarch butterfly , bees , and other pollinators in small gardensDr . D. Potter , University of KentuckyThe debate over the value of straight species vs cultivar of native plant ( called nativars ) has clouded consumers ’ understanding of the time value of certain plant to monarch butterfly . Nativars are var. of aboriginal species choose and vegetatively propagate for desirable attributes , such as plant stature , flower or leaf color , or blossom period . Do nativars of milkweed supply the same benefits to monarchs ? Dr. Potter and his team will help discharge the mental confusion and tone up the gardening industry ’s stance that native plant cultivars of milkweed can have the same or even higher preservation value than straight specie .

Biocontrol agents for the transmitter of rose rosette virusDr . I. Tzanetakis , University of ArkansasRose rosette disease ( RRD ) threatens landscape and production blush wine alike , particularly since it reemerged recently in California .
