Previously the author carrid out the intravenous glucose tolerance test with rats, and reported that the glucose tolerance curve for the adrenalectomized animal returned to the pre-operative level on the administration of hydrocortisone acetate (Tobe, 1957). Recently new compounds representing modifications of cortisone and hydrocortisone have appeared. Fried and Sabo(1953, 1954)showed that hal...

In Citrus, water, nutrient transport and thereby fruit production, are influenced among other factors, by the interaction between rootstock and boron (B) nutrition. This study aimed to investigate how B affects the anatomical structure of roots and leaves as well as leaf gas exchange in sweet orange trees grafted on two contrasting rootstocks in response to B supply. Plants grafted on Swingle c...

THE most recent account of the digestive processes of the cockroach is that given by Swingle [1925], who employed the Common Cockroach (Blatta orientalis) in his experiments and whose conclusions are briefly as follows. The salivary glands produce only an amylase. The hepatic caeca of the midgut produce an invertase, maltase, lipase and protease. The remainder of the mid-gut (stomach) secretes ...

1. Indirect plant defences are well documented for the above-ground constituents of plants. Although less investigated to date, below-ground defences that mediate multitrophic interactions are equally important. Entomopathogenic nematodes (Steinernema diaprepesi) are attracted to herbivore-induced volatiles from Swingle var. (Citrus paradisi · Poncirus trifoliata) when fed upon by root weevil,D...

The length of citrus seedling development is determined by several factors, including the physical and chemical qualities substrate, which affect rootstock growth and, as a result, quality field seedlings. purpose this study was to see how ‘Swingle’ citrumelo developed with different substrate formulations. experiment carried out in nursery from seeding grafting, six treatments were out, follow...

This study was aimed to examine the antibacterial and antioxidative properties of seven edible plants from Thailand to develop alternative antibiotics as feed additives. The plants include Citrus aurantifolia Swingle (Lime) fruits and its leaves, Sesbania grandiflora L. (Agati sesbania) leaves, Piper sarmentosum Roxb (Wild betal) leaves, Curcuma domestica Valeton (Turmeric) roots, Morinda citri...

Three-year-old citrus trees were grown in the greenhouse to study the effects of fertilizer concentration and root herbivory on plant growth and mineral concentration. In separate experiments, sour orange (Citrus aurantium L.) and Swingle citrumelo (C. paradisi Macf. Poncirus trifoliate L.) plants were treated with a complete fertilizer diluted to provide 25, 100, 200, or 400 ppm N and grown fo...

The infectivity of five populations of Tylenchulus semipenetrans were compared and differentiated on 10 hosts (5 Citrus spp., 1 Poncirus trifoliata, and 4 hybrids of Citrus spp. X P. trifoliata). Differences in levels of infection and development (P = 0.01) occurred between Citrus spp. and P. trifoliata cv. 'Pomeroy' and their three hybrids, C. paradisi X P. trifoliata cv. 'Swingle' citruntelo ...

A morte súbita dos citros (MSC) é uma doença biótica de origem desconhecida, transmitida por vetores aéreos e borbulhas, que afeta cultivares laranjas doces tangerinas enxertadas nos limoeiros Cravo, Volkameriano Rugoso. As mesmas nas Cleópatra Sunki, trifoliata citrumelo Swingle são assintomáticas. O objetivo deste trabalho foi avaliar nove seleções quanto à tolerância MSC seus efeitos no dese...

based on the valuable antioxidant activity of citrus fruits, in present study the effect of ‎rootstock and the type of tissue on some fruit quality parameters including phenol, ‎flavonoid, antioxidant and the content of hesperidin and naringin of orange and mandarin ‎was studied. the experiment was conducted as a factorial design based on complete ‎randomized blocks with four replications. resu...
