The rice white tip nematode (RWTN), Aphelenchoides besseyi and the chrysanthemum foliar nematode (CFN), Aphelenchoides ritzemabosi are migratory plant parasitic nematodes that infect the aboveground parts of plants. In this research, Arabidopsis thaliana was infected by RWTN and CFN under indoor aseptic cultivation, and the nematodes caused recognizable symptoms in the leaves. Furthermore, RWTN...

Computer simulations similar to actual trees were constructed using simple branching rules. Branch orientation with respect to the direction of gravity was a fundamental consideration. In Cornus kousa BUERG. ex HANCE, several types of branches develop from winter buds, varying from orthotropic shoots to plagiotropic ones. Based on actual observations and measurements of branching structures wit...

This paper describes a prime and easy-touse protocol for large-scale production of plant lets through shoot tip culture of Lantana camera, the plant having phytoremediation potential and the method is useful for the ex-situ conservation of other species important for phytoremediation. A simple micro-propagation method from nodal and shoot tip explants were reported here for Lantana camera, at c...

Demand for therapeutic honey is driving establishment of Leptospermum plantations. This study developed micropropagation methods two species – polygalifolium Salisb. and L. scoparium J.R.Forst. & G.Forst. The determined how shoot proliferation adventitious rooting were influenced by the original explant position on seedling concentration benzyladenine (BA) in medium. Hormone-free node cultu...

Studies were conducted to relate the influence of the physical characteristics, leaf nutrient content and phloem sap amino acid concentration of citrus flush shoots on the densities of various Diaphorina citri life stages. Adult D. citri preferentially selected young shoots for feeding and numbers of D. citri immatures were positively correlated with flush shoot softness. Young flush shoots had...

ture and needle morphology on the distributions of light and nitrogen within a Pacific silver fir (Abies amabilis (Dougl.) Forbes) canopy. Specifically, we investigated the role of morphological shade acclimation in the determination of resource use efficiency, which is claimed to be optimal when the distribution of nitrogen within the canopy is directly proportional to the distribution of inte...

Studies were conducted in early 2003 to determine the effect of root source and length on yield of adventitious shoots and plant yield from root cuttings of Arkansas-developed thornless blackberries. In the first study, roots from ‘Arapaho’ and ‘Apache’ plants grown in an aboveground bed containing commercial potting soil were compared to field-grown roots. Bed-grown roots averaged 6.9 shoots p...

We studied the effects of variation in shoot structure and needle morphology on the distributions of light and nitrogen within a Pacific silver fir (Abies amabilis (Dougl.) Forbes) canopy. Specifically, we investigated the role of morphological shade acclimation in the determination of resource use efficiency, which is claimed to be optimal when the distribution of nitrogen within the canopy is...
