Gulma merupakan tumbuh-tumbuhan yang keberadaanya tidak diharapakan dan tumbuh secara liar di lahan budidaya. Pertumbuhan gulma menyebabkan permasalahan pada perkebunan kakao karena menggangu hasil produktivitas, sehingga perlu dilakukan pengendalian. Tujuan dari penelitian ini yaitu mengetahui efektivitas herbisida berbahan aktif 2,4 – D Dimetil Amina tanaman menghasilkan PTPN XII Kendenglembu...
Function of leaf hamamelitol as a compatible solute during water stress treatment of Hedera helix L.
The role of light in cold acclimation of Hedera helix L. var. Thorndale appears to differ from that reported for winter annuals. Although light greatly enhances the degree of hardiness attained, cold acclimation is not obligatorily linked to a light requirement. Photoperiods, varying from 8 to 24 hours, received during the cold acclimation period were equally effective in promoting maximum hard...
It has been much disputed whether seasonal variations in proteins or in sugars are better related to cold hardiness changes in certain over-wintering plants (for example, 1, 2, 3, 8, 12, 14). But proteins have been difficult to study, since they are not easily extracted from such plants as our native winter-hardy trees. This is because such proteins are often precipitated by vacuolar substances...
Bio-inspiration for novel adhesive development has drawn increasing interest in recent years with the discovery of the nanoscale morphology of the gecko footpad and mussel adhesive proteins. Similar to these animal systems, it was discovered that English ivy (Hedera helix L.) secretes a high strength adhesive containing uniform nanoparticles. Recent studies have demonstrated that the ivy nanopa...
