The physiology of plagiotropic growth of rooted cuttings of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco]

Creator:: Starbuck, Christopher J.
Abstract:: Experiments were conducted to determine if the plagiotropic growth habit of rooted cuttings of Douglas-fir might result from a system favoring the accumulation of indoleacetic acid in the adaxial side of the shoot in response to vertical placement. Actively growing excised branch terminals were subjected to gravitational disorientation to determine...

Effects of inoculations with pathogenic and beneficial microorganisms and ammonium of nitrate fertilization on Easter lily growth

Creator:: Valenciano Mora, Jose Roberto
Abstract:: Although chemical fungicides are commonly used to control fungal soil-borne diseases of Easter lilies, Lilium longiflorum Thunb., in field production and greenhouse forcing, cultural and biological controls may be alternatives or complementary to chemicals for control of pathogens. The influence of inoculations with beneficial, symbiotic, and biocontrol microorganisms to enhance...

Effect of pruning and training time on yield components and cold hardiness of 'Marion' blackberry

Creator:: Bell, Neil (Neil Charles), 1961-
Abstract:: The effect of primocane removal and training time on yield components and cold hardiness of 'Marion' trailing blackberry was studied. In 1991, primocanes were either not cut, or cut at ground level from plants on a single occasion at one month intervals from late April to late July. Four canes...

Xylem discontinuity in Vitis vinifera L. berries

Creator:: Creasy, Glen L.
Abstract:: Several effects of xylem discontinuity in Pinot noir and Merlot grape berries were studied. There was a reduction in the amount of apoplastic dye (Eosin Y or azosulfamide) uptake through cut pedicels into soft versus firm berries, suggesting a reduction in maximal xylem flow at that time. Both greenhouse and...

Nitrogen partitioning and remobilization in field-grown apple trees

Creator:: Khemira, Habib
Abstract:: Uptake and cycling of nitrogen (N) in mature trees are not well understood. Fertilizer-N uptake, partitioning, and use-efficiency were studied in standard strain 'Topred Delicious' and spur strain 'Redspur Delicious' mature apple trees {Malus domestica Borck) on 'Malling 7A' (M.7A) rootstocks. The treatments consisted of a ground application in spring,...

The effects of light on photosynthesis and rooting of leafy cuttings of Pisum sativum L.

Creator:: Davis, Tim D.
Abstract:: The effects of light incident on leafy cuttings is quite complex because' light influences several factors which may affect root formation. One effect of light is to influence the carbohydrate status of the cutting by influencing photosynthesis. The role of current photosynthate in the rooting of leafy cuttings is uncertain....

Ripening pear flavor volatiles : identification, biosynthesis and sensory perception

Creator:: Suwanagul, Anawat
Abstract:: Volatile compounds of eight pear varieties were isolated and identified by GC/MS. A total of 112 components were identified from headspace of intact fruits, including 47 compounds reported for the first time in pear. The volatile profiles of these pear varieties were characterized by esters, alcohols, hydrocarbons, aldehydes and ketones....

Influence of photosynthesis and carbohydrates on adventitious root formation by leafy cuttings

Creator:: Davis, Tim D.
Abstract:: Many investigators have suggested that current photosynthate supply can limit adventitious root formation on leafy cuttings. Accordingly, studies were undertaken to determine the effects of altering photosynthesis and carbohydrate levels on adventitious root formation by leafy cuttings of a number of different species. Pea cuttings rooted at high CO₂ (1800...
