Three independent recessive mutations at the SPINDLY (SPY) locus of Arabidopsis confer resistance to the gibberellin (GA) biosynthesis inhibitor paclobutrazol. Relative to wild type, spy mutants exhibit longer hypocotyls, leaves that are a lighter green color, increased stem elongation, early flowering, parthenocarpy, and partial male sterility. All of these phenotypes are also observed when wi...

David P. Horvath USDA–Agricultural Research Service, Plant Science Research, 1605 Albrecht Boulevard, Fargo, ND 58105-5674 Signals from both leaves and apical or axillary meristems of leafy spurge are known to inhibit root bud growth. To test the hypothesis that carbohydrates and growth regulators affect root bud growth, decapitated leafy spurge plants were hydroponically treated with glucose, ...

Aplikasi paclobutrazol pada tanaman padi untuk mengurangi tinggi batang merupakan strategi adaptasi terhadap perubahan iklim yakni agar lebih tahan rebah. Namun demikian, pengaruh aplikasi kualitas beras masih jarang diteliti. Penelitian bertujuan mengkaji mutu dari empat varietas yang diberi perlakuan paclobutrazol. dilaksanakan bulan Februari-Juli 2021 di Kebun Percobaan Sawah Baru IPB, Bogor...

The effect phytohormones dry herbage yield harvest found sig...

Tomatoes are a horticultural commodity that has the potential to be developed because it high economic value and great export potential. The increase in tomato needs is often not offset by increased production so Indonesia been able meet of national tomatoes, addition issue food quantity shifted quality safety using natural ingredients. This study aims determine concentration paclobutrazol can ...

Practices to promote tree root growth have been sought in arboriculture for many years, especially as a treatment for trees that are stressed or in decline. Tree fertilization is a common practice in arboriculture. A few research reports have shown that nitrogen fertilization can increase fine-root density in localized areas of soil where the fertilizer has been applied, but the effect on the w...

Objectives—The dominant route of occupational exposure to pesticides in horticulture is dermal. However, preventive measures are seldom used when handling plant cultures recently treated with pesticides, thus causing significant dermal exposure and potential absorption. Assessment of exposure often depends on biological monitoring of blood or urine samples. The skin often acts as a temporary re...

Small Shorea stenoptera Burck. (Dipterocarpaceae) trees of reproductive age growing in an arboretum in west Java were studied to determine the pattern of vegetative shoot development, the time and method of floral initiation and the effect of paclobutrazol on floral enhancement. Vegetative buds were enclosed by two stipules between which was a leaf primordium, a small axillary vegetative bud an...

BACKGROUND AND AIMS Gibberellin stimulates negative gravitropism and the formation of tension wood in tilted Acacia mangium seedlings, while inhibitors of gibberellin synthesis strongly inhibit the return to vertical growth and suppress the formation of tension wood. To characterize the role of gibberellin in tension wood formation and gravitropism, this study investigated the role of gibberell...
