Rambutan ( Nephelium loppacum L.) is a fruit native to Indonesia with the nature of seasonal fruit . Production outside of rambutan season still has not been done in scale commercial venture . Rambutan trees will naturally be difficult to bear fruit twice a year ,
due to the induction of flowering depends on environmental factors to
grow .
On entering the phase rproduktif , rambutan able to generate a lot of interest . Relationship usually appear on Poster tersebut.malai formed in flower has many ramifications . In each branch appears a lot of interest . Flowers grow on the ends of the twigs are often found growing along with the emergence of new leaves . 7 years old rambutan tree is able to produce 600-800 panicles of flowers per tree , in a panicle panicles are about 17-28 children . Each individual flower panicles containing 500-1700 ( liferdi , 2000)
Induction of flowering of rambutan can be done in various ways among the trunks and crates of water stress . The application of these methods is strongly influenced by local weather conditions / microclimates and reserve status in plant foods , since both strongly affected the flowering and fruiting rambutan . In Indonesia, rambutan fruit only once a year , with harvest season ranges from December - February . In areas with continuous musimhujan pattern , irregular flowering time . The intensity of flowering is closely linked to the level and duration of plant water stress .
Rambutan tree trunk slices are given treatment and followed by treatment with KNO3 spraying as much as 40 g / liter capable of flowering 30 days earlier compared to control trees . The success of this treatment greatly influenced when does the stem slices . Stem slices were made at the time of going into the phase of slow-growing tree , which has been active Trubus telewati , will be able to induce flowers , while the slices are done on a tree trunk that trubusnya still active ( young vegetative shoots ) berdeda flowering time is not real with control trees ( Poerwanto and Irdiastuti , 2003) . Treatment crate can also induce flowering stems off season -on-year during the off season and rambutan flowering during the off year . Treatment rod crate should only be performed on physically healthy trees . Pengeatan twice in two consecutive years could jeopardize the survival of the tree due to scar tissue filter area is difficult to form.
In addition to water stress treatment stem slices can be used to stimulate flowering because ramputan give a positive response to a brief period of kekereingan necessary for flower formation . Flowering intensity associated with the level and duration of plant water stress . Flower emergence is closely linked to the presence of the dry season that followed once the rain once . Liferdi research results ( 2000) showed that the rambutan requires a dry period before flowering . After experiencing a dry spell for a month , rambutan flowers appear about two weeks after a rain or after watering down again .
Paklobutrazol rambutan can induce flowering in off year mas . Rambutan treated paklobutrazol 1.5 g / tree and 3 g / plant significantly increased the number of generative shoots and increase the chlorophyll content of leaves which underpins the fruit compared to control trees . The optimum dose to induce flower is 1.5 g / tree because the dose is not menyebebkan dormant buds , while a dose of 3 g / tree causing dormant buds that need to be followed by administration of dormancy -breaking agents , KNO3 .
