in this research, possibility of bulblet production from different cuttings including leaf, leaf-bud and leafy-stem of lilium oriental hybrid cv. ‘star gazer’ evaluated under different levels of indole-3-butyric acid (iba) with 0, 250, 500, 750 and 1000 mg per liter (ppm). the cuttings were taken from stems which grown from cold treated bulbs in early october. a factorial experiment was done in...

this study was performed to evaluate the efficacy of injection of essential oil of eugenia caryophyllata in the kid horn buds, as a new chemical technique for disbudding. five-day-old healthy goat kids from both sexes (n = 16) were divided randomly into 4 equal groups. in groups 1, 2 and 3, 0.2 ml of clove essence and in group 4 (control) 0.2 ml of normal saline was injected into the left horn ...

background: the purpose of dehorning in cattles is to decrease injuries and increase security in farms. besides breeding managements, different chemical and physical methods are used for dehorning of livestock, depending on their age, each of which has advantages and disadvantages. objectives: this study was performed to evaluate the effects of clove oil on disbudding new born calves following ...

primary bud necrosis in grapevine is a physiological disorder observed in the compound buds. this study was conducted to investigate the anatomical changes in cv. askari grapevine in winter dormant buds. bud samples were taken from askari grapevine at sisakht vineyards, south-western of iran. compound buds were dissected and assessed under a binocular microscope at 10-40x magnification and a di...

In this work, the grafting of maleic anhydride onto two types of linear low density polyethylene with hexene-1 comonomer (LLDPE-H1) and butene-1 comonomer (LLDPE-B1), in the presence of styrene monomer (St) and dicumyl peroxide initiator (DCP) has been studied. The combined influences of MAH, St and DCP on the grafting efficiency via a melt reactive mixing process have been investigated using r...

BACKGROUND AND AIMS In trees, bud development is driven by endogenous and exogenous factors such as species and climate, respectively. However, knowledge is scarce on how these factors drive changes in bud size across different time scales. METHODS The seasonal patterns of apical bud enlargement are related to primary and secondary growth in two coexisting Mediterranean oaks with contrasting ...

A new sort of combinatorial generating system, called bud generating system, is introduced. Bud generating systems are devices for specifying sets of various kinds of combinatorial objects, called languages. They can emulate context-free grammars, regular tree grammars, and synchronous grammars, allowing to work with all these generating systems in a unified way. The theory of bud generating sy...

it is necessary to determine the amount of chilling requirement of present cultivars and also to produce new low chill cultivars through breeding programs because of the global warming phenomenon and tendency to grow temperate fruit in warm climate. in this study, the amount of chilling requirement in ‘askari’, ‘rotaby’, ‘yaghuty’, ‘rish baba’ and ‘monaga΄ were evaluated. uniform cuttings of me...

Wintering flower buds of cold hardy Rhododendron japonicum cooled slowly to subfreezing temperatures are known to undergo extraorgan freezing, whose mechanisms remain obscure. We revisited this material to demonstrate why bud scales freeze first in spite of their lower water content, why florets remain deeply supercooled and how seasonal adaptive responses occur in regard to extraorgan freezing...
