Avancer la date de r\u00e9colte sans sacrifier la qualit\u00e9 du fruit est l\u2019un des grands d\u00e9fis du viticulteur. Un essai r\u00e9alis\u00e9 sur raisin de table vari\u00e9t\u00e9 Krissy montre que Brixtoner Vital non seulement le rend possible, mais am\u00e9liore aussi de fa\u00e7on significative la teneur en solides solubles et l\u2019uniformit\u00e9 de couleur des grappes.<\/p>\n\n\n\n
Les r\u00e9sultats sont clairs\u00a0: des fruits plus sucr\u00e9s, \u00e0 la couleur plus uniforme et r\u00e9colt\u00e9s plus t\u00f4t. Trois avantages concurrentiels en une seule solution.<\/p>\n\n\n\n
L\u2019essai\u00a0: m\u00e9thodologie et contexte<\/h2>\n\n\n\n
L\u2019essai a \u00e9valu\u00e9 l\u2019effet de trois applications de Brixtoner Vital sur le d\u00e9veloppement de la couleur, la teneur en solides solubles et la pr\u00e9cocit\u00e9 de r\u00e9colte sur raisin de table vari\u00e9t\u00e9 Krissy. Le dispositif \u00e9tait un plan compl\u00e8tement al\u00e9atoire, avec un suivi de 25 grappes par traitement depuis la premi\u00e8re application jusqu\u2019au premier passage de r\u00e9colte.<\/p>\n\n\n\n
Le t\u00e9moin correspondait \u00e0 la conduite habituelle sans biostimulant.<\/p>\n\n\n\n
72\u00a0%<\/strong> de grappes en pleine couleur contre 44\u00a0% pour le t\u00e9moin<\/td>
+7,1\u00a0%<\/strong> de \u00baBrix par rapport au t\u00e9moin<\/td>

R\u00e9sultats\u00a0: trois am\u00e9liorations mesurables<\/h2>\n\n\n\n
1. Un d\u00e9veloppement de la couleur plus rapide et plus uniforme<\/h3>\n\n\n\n
\u00c0 la date de r\u00e9colte, 72\u00a0% des grappes trait\u00e9es<\/strong> avaient atteint la \u00ab\u00a0pleine couleur\u00a0\u00bb, contre seulement 44\u00a0% pour le t\u00e9moin<\/strong> \u2014 une diff\u00e9rence statistiquement significative (khi-deux de Pearson, p<0,05).<\/p>\n\n\n\n
La couverture de la charge fruiti\u00e8re totale a \u00e9t\u00e9 de 95,5\u00a0%<\/strong> avec Brixtoner Vital contre 86,1\u00a0% pour le t\u00e9moin<\/strong> \u2014 pr\u00e8s de 10 points de pourcentage, avec une significativit\u00e9 statistique (ANOVA, p<0,05).<\/p>\n\n\n\n
2. Une r\u00e9colte plus pr\u00e9coce et plus efficace<\/h3>\n\n\n\n
Au premier passage, 76,3\u00a0% des grappes trait\u00e9es<\/strong> ont \u00e9t\u00e9 r\u00e9colt\u00e9es contre 69,4\u00a0% pour le t\u00e9moin<\/strong>. Cet \u00e9cart de 6,9 points se traduit par moins de journ\u00e9es de r\u00e9colte, un co\u00fbt op\u00e9rationnel r\u00e9duit et une fen\u00eatre commerciale plus pr\u00e9coce.<\/p>\n\n\n\n
3. Une teneur en solides solubles plus \u00e9lev\u00e9e (\u00baBrix)<\/h3>\n\n\n\n
Les grappes trait\u00e9es ont atteint 21,05 \u00baBrix<\/strong> contre 19,65 \u00baBrix pour le t\u00e9moin<\/strong> \u2014 soit +7,1\u00a0%, statistiquement significatif<\/strong> (ANOVA, p<0,05). Un \u00baBrix plus \u00e9lev\u00e9 signifie une douceur plus perceptible pour le consommateur et une plus grande valeur commerciale.<\/p>\n\n\n\n
Brixtoner Vital a avanc\u00e9 la r\u00e9colte, am\u00e9lior\u00e9 l\u2019uniformit\u00e9 de couleur et augment\u00e9 la teneur en sucre du fruit de 7,1\u00a0%. Trois indicateurs cl\u00e9s de qualit\u00e9 et de rentabilit\u00e9 am\u00e9lior\u00e9s au cours d\u2019un m\u00eame cycle.<\/em><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n

Pourquoi Brixtoner Vital fonctionne<\/h2>\n\n\n\n
Brixtoner Vital est un biostimulant formul\u00e9 sp\u00e9cifiquement pour la phase de maturation des arbres fruitiers et de la vigne. Sa composition int\u00e8gre\u00a0:<\/p>\n\n\n\n
Du phosphore soluble (P2<\/sub>O5<\/sub> \u00e0 12\u00a0%), essentiel \u00e0 la mobilisation des sucres et \u00e0 leur accumulation dans le fruit.<\/p>\n\n\n\n
Des acides amin\u00e9s et des polysaccharides, qui agissent comme activateurs m\u00e9taboliques en fin de maturation.<\/p>\n\n\n\n
Du magn\u00e9sium, du zinc et du bore, impliqu\u00e9s dans la synth\u00e8se des pigments, la qualit\u00e9 de la couleur et l\u2019efficacit\u00e9 photosynth\u00e9tique.<\/p>\n\n\n\n
L\u2019association de ces composants acc\u00e9l\u00e8re les processus physiologiques de maturation, favorise l\u2019uniformit\u00e9 de couleur et renforce la concentration en sucres, sans alt\u00e9rer la fermet\u00e9 ni la dur\u00e9e de conservation apr\u00e8s r\u00e9colte.<\/p>\n\n\n\n
Applicable au-del\u00e0 du raisin<\/h2>\n\n\n\n
Brixtoner Vital est con\u00e7u pour \u00eatre utilis\u00e9 sur tout arbre fruitier ou vigne pendant la phase de maturation. Il est particuli\u00e8rement utile lorsque l\u2019uniformit\u00e9 de couleur, la teneur en sucres ou la pr\u00e9cocit\u00e9 de r\u00e9colte sont des param\u00e8tres commercialement d\u00e9terminants\u00a0: cerises, prunes, p\u00eaches, poires ou agrumes, entre autres.<\/p>\n\n\n\n
