Acúmulo de carboidratos no desenvolvimento de tomateiro tratado com produtos químicos

This work had the purpose to study the physiological effects of pyraclostrobin, boscalid, plant growth regulators and plant extract on the accumulation of carbohydrates during the development of tomato plants (Solanum lycopersicum L.), hybrid Giuliana, in protected environment conditions. The treatments were: T1- control; T2- pyraclostrobin 0.2 g L-1; T3- boscalid 0.075 g L-1, T4- pyraclostrobin 0.2 g L-1 + boscalid 0.075 g L-1, T5- IBA + GA(3) + kinetin 375 mg L-1, T6- GA(4+7) + benzylaminopurine 100 mg L-1 and T7- plant extract 100 mg L-1. The carbohydrate accumulation curve was accomplished with 5 samples, at 20-day intervals between evaluations, the 1st evaluation being carried out at 30 days after transplantation, on the day of the first treatment application. At each sampling the plants were separated in stem, leaves and fruits, of which the contents of total soluble sugars, reducing sugars and saccharose were evaluated. The effects of the treatments on chlorophyll content and gas exchanges were also evaluated. The experimental design was completely randomized, with 4 repetitions and 6 destructive evaluations during the development, with 1 plant per experimental unit for each sampling. The pyraclostrobin and boscalid applied in isolation and/or combined favor the increase of carbohydrates in leaves, stems and fruits of tomato hybrid Giuliana.

Performance of cucumber hybrids cultivated in coconut fiber and soil

The objective of this work was to evaluate the performance of three Japanese group cucumber hybrids, which were cultivated in two cultivation systems. The experiment was designed in a split-plot randomized block design with two cultivation systems (coconut fiber and soil) for commercial Japanese cucumber hybrids ('Tsuyataro', 'Yoshinari' and 'Nankyoku'). After harvesting the cucumbers, we evaluated the number of marketable fruits per plant, the average fruit length, the mean fruit diameter, the bottom fruit diameter, the marketable production of fruits per plant and the marketable yield per hectare. There were significant interactions between the cultivation system and the hybrid, as indicated by the number of marketable fruits. The Nankyoku hybrid had the highest average (14.54 fruits pl(-1)), although it did not differ from the Yoshinari hybrid when grown in coconut fiber. In soil culture, the Yoshinari hybrid had the highest average number of fruits per plant (10.12 fruits pl(-1)) and did not differ from the Tsuyataro hybrid. Cultivation in coconut fiber provided better results for production traits and plant productivity. 'Yoshinari' and 'Nankyoku' were the most productive hybrids. Based on the cucumber cultivation results from a protected environment, the cultivation of hybrid Japanese cucumbers and Yoshinari and Nankyoku hybrids in coconut fiber is recommended.

Teores de macronutrientes em plantas de pimentão enxertadas sob fertirrigação

This study aimed at determining the levels of macronutrients (N, P, K, Ca, Mg and S) in grafted plants by contact methods such as bevel, cleft grafting by full rift and approach, as compared to non grafted plants. Analyses were performed in different parts of the plants under fertigation in a greenhouse. The hybrid and rootstock were AF 7125 and AF 8253, respectively. The nutrients were supplied via fertigation during the 150-day cycle. The experiment was carried out at the Teaching, Research and Production Farm in São Manuel city, SP which belongs to FCA-UNESP Campus in Botucatu city/SP. A total of 4 treatments and 5 replications were used. Each plot consisted of 12 plants. Chemical analyses were performed in one plant per plot at 35, 85, 112 and 143 days after transplantation to determine nutrient concentrations. The results showed that the macronutrient concentrations in a decreasing sequence in the vegetative parts (leaf + stem) were as follows: K > N > Ca > Mg > S > P; and in the fruits: K > N > P > S > Mg > Ca. Macronutrient concentrations were similar among grafted plants as compared to ungrafted plants, and the rootstock may have influenced absorption and translocation of minerals in grafted plants.
