Effects of Transplant Container and Solanam Rootstocks on the Incidences of Overgrowth and Unmarketable Fruits in Tomato Plants Planted with Plug Seedlings.

Abstract

The incidences of overgrowth and unmarketable fruits were compared between tomato autografts planted with 50 mL plug and those with 800 mL pot (control), and the regulation of such incidences were tried with Solanum rootstocks. Planting with plug promoted the early growth of tomato plants and the growth was regulated by Solanum rootstocks. S. melongena rootstock suppressed the overgrowth and kept vigor similarly to that of the control autograft, whereas S. integrifolium and S. torvum rootstocks decreased the growth more than S. melongena. Thickening and aerial rooting at scion base, phenomena of graft incompatibility, were observed in the heterograft on S. torvum. Marketable fruit weight was lower in planting with plug than that with pot in tomato autografts, but unmarketable fruit weight, especially cracking fruits, markedly increased by planting with plug. Among grafts on various rootstock species, marketable fruit weight was the largest in S. melongena rootstock and the smallest in S. torvum rootstock. The marketable fruit weight of the heterograft on S. melongena planted with plug was similar to that of control plants. Planting of the tomato plugs decreases marketable fruit yield through cracking of the fruits. However, such deteriolation is ameliorated by S. melongena rootstock.

EFFECT OF DIFFERENT ROOTSTOCKS ON GROWTH, CHLOROPHYLLAFLUORESCENCE AND MINERAL COMPOSITION OF TWO GRAFTED SCIONS OF TOMATO

“…These results confirm previous data obtained by Oda et al (2000), who studied the effect of different rootstocks on tomatoes in which the growth of scions was depressed and where stems at the graft union thickened markedly 18 weeks after grafting. In contrast, another study (Oda et al, 2005) indicated that little or no effect of rootstocks species appeared on the growth of tomato plants scions except for an increase of stem thickening at the graft union.…”

Compatibility Evaluation and Anatomical Observation of Melon Grafted Onto Eight Cucurbitaceae Species

“…'Hongmianmiyou' and 'Huangjinmiyou' were grafted onto Poncirus trifoliata (Gong et al, 2016). Tomato/pepper healing junction showed the asynchronous stem bulging 30 days after grafting (Masayuki et al, 2000;Thomas et al, 2021), which was also observed in graft incompatible melon (Cohen et al, 2007;Zhou et al, 2018).…”

Analysis of Plant Growth and Yield in Varieties of Tomato (Solanum lycopersicum L.) Grafted onto Different Eggplant Rootstocks

“…e idea of grafting tomato onto eggplant is not new and has been successfully performed in the past in tropical conditions [12]. Moreover, it can increase marketable yield [13], manage soilborne diseases [14], and improve alkalinity tolerance [15], in accordance with the specific characteristics and problems of each agroecosystem. e selection of compatible rootstocks using local genetic resources is expected to address local issues and be more practical than using imported resources.…”
