Lateral development in roots and shoots of Pinus radiata seedlings
… in this thesis. Responses of pine seedling shoots to root-applied growth substances were studied. These experiments, along with some interesting observations on the proliferation of short-shoots, and some preliminary results on rooting of cuttings and the ability of mycorrhizal fungi to …

Needleless shoots and loss of apical dominance in greenhouse-grown loblolly pine (Pinus taeda L.)
… in the form of multiple apical and needleless shoots. Seedlings that exhibit growth abnormalities are of questionable value in the evaluation of progeny tests. The use growth data from this seedling material could result in biased and erroneous or invalid conclusions about individual tree or …

Nutritional and Bioactive Characterisation of Faba Bean (Vicia faba L.) Green Shoots as a Protein-Rich Leafy Vegetable
… and biochemical characterisation of faba bean shoots (Vicia faba L.), hereafter referred to as faba greens, to investigate their potential as a sustainable, nutrient–rich alternative to imported leafy vegetables. Although faba beans are traditionally grown for their mature seeds in …

Comparison of soil properties and Kentucky bluegrass shoots mineral composition prior to and after 10-11 years irrigation with recycled water
In Colorado, fresh water is one of the most valuable and limited natural resources. Due to population growth, an increase of fresh water withdrawal has been reported by U.S. Geological Survey. Irrigation with recycled water has been utilized as a means to alleviate the stress on potable water …

Variation in growth, nutrition and phytochemicals of sequentially harvested shoots and fruits, and genetic studies of Lagenaria siceraria landraces in South Africa
… source with edible plant parts such as leaves, shoots, fruit pulp, and seeds. However, studies on L. siceraria regarding the relationship between shoot, peduncle and fruit traits during growth; nutritional and phytochemical composition of sequentially harvested shoots and fruits; as well as …

The life history of Grimmia pulvinata (Hedw.) SM. and Tetraphis pellucida Hedw. in the laboratory and in the field
… intensity although internode lengths of leafy shoots were not affected. Quantitative studies of cultures from single gemmae grown under coloured filters suggested a complex interaction of photosystems in the protonema. Study of shoots grown on agar with added glucose or mannitol suggested that …

The effect of 6-benzylamino purine on axillary bud growth of Ilex crenata Thunb. 'Rotundifolia'
… resulted in a 68% increase in total numbers of shoots per plant over control plants. Applications of BA at 600 ppm and 800 ppm to individual shoots resulted in swelling of the terminal 4-5 cm section of treated stems and development of a red pigment followed by growth of numerous axillary shoots …

Comparisons of three popular rose (Rosa Hybrida L.) cultivars
… 10 and 25 days after pinch, and at flowering, 5 shoots from each bench location were destructively sampled for leaf (node) number, stem length, stem diameter, and fresh and dry weights of stem, leaves, flower bud, and total. Time to visible bud, to color, and to flower from pinch were recorded as …

The biology of poplar rust in the South Western Cape with special reference to the carbon physiology of the host-biotroph relationship
… morphological changes in the leaves of infected shoots suggested that the rust was a benign obligate biotroph which, in the absence of its alternate hosts, appears to be adapted to a compatible existence with one host. The ready availability of poplar stands in the South Western Cape which are …

Rapid multiplication of cassava (Manihot esculenta Crantz.) as a potential method to provide disease-free plant materials
… LIMO and AMM solid phase, taller (3 cm), single shoots with $>$3.5 roots per explant were produced, while with APM and GA$\sb3$ cultures were shorter, multiple shoots but without roots. Double phase medium of either AMM or APM with GA$\sb3$ in the LIMO, induced $>$5 dissectable nodes vs 2 nodes …

In vitro micropropagation, evaluation of disease resistance and hardiness of several new rose cultivars
… of these cultivars were the source of explants. Shoots obtained from axillary buds proliferated when they were cultured on a modified MS medium supplemented with combinations of BA and TDZ. Leaves and roots of 'Carefree Beauty', 'Prairie Youth' and 'John Frobisher' failed to regenerate shoots in …

Stability of 'Thornless Evergreen' Blackberry in Vitro and Ex Vitro (Tissue Culture, Chimera, Variability, Somaclonal Variation, Rubus)
… of cells with a thorny genotype. Adventitious shoots from roots are always thorny, and gametes carry the thorny gene. Via micropropagation, pure thornless plants were selected from rapidly propagated shoot tips. These pure thornless plants had shortened internodes and a characteristic "bent …

Seasonal Changes in Biomass of Two ComFreshwater Wetland plants: storage of nutrients
… contained larger amounts in roots than shoots, and the opposite was observed in the control specimens. Also, dosed specimens of T. latifolia contained higher amounts of potassium in roots compared to shoots/leaves, whereas the control specimens contained higher amounts of potassium in …

Development of a Laboratory Protocol for the Micropropagation of Monterey Pines (<i>Pinus Radiata</i>), Año Nuevo Stand
… used in the trial that induces the growth of new shoots. The final protocol developed in this project describes, step-by-step, the media preparation for the initiation, plant material collection, surface sterilization of plant material, plating in media and initiation of shoots on explants. The …

De novo morphogenesis on tomato thin cell layers and variation for genetic recombination among plantlets regenerated from tissue culture
De novo shoots, roots, and flower buds were regenerated on thin cell layer explants excised from pedicel tissue of tomato. Direct shoot organogenesis was greatest when media contained 10µM kinetin and 0.001µM indole-3-acetic acid (IAA); however, shoot regeneration was increased in subsequent …

The effect of phosphorus fertilizer and bradyrhizobium innoculation on grain yield and nutrients accumulation in two chickpea (Cicer aritienum L.) genotypes
… of nutrients accumulation in the rhizosphere, shoots and grain of chickpea, especially when determined at different growth stages in the African continent. This study contributes knowledge on this crucial aspect which will likely lead to more other similar research reports in other settings. …
